Guide to Detect and Solve Car AC Compressor Not Turning On Problem


The car AC compressor doesn’t turn on is an annoying problem. Here, you can find how to detect this problem and the best solution you can use to return the AC system works well like before

Guide to Detect and Solve Car AC Compressor Not Turning On Problem

Is your car ac compressor not turning on? This condition could lead to many critical problems with the car AC system. For that reason, we have a guide on how to deal with the problem. So, keep reading and find out more about everything you need to know about car AC compressor problems.

Car AC Compressor Explanation and What It Does

A car AC system consists of several parts. They are the compressor, evaporator, condenser, receiver-dryer, refrigerant, and expansion tube. The compressor is the core of the entire AC system cooling process. It creates a cycle that processes the air and cools it down, creating a comfortable environment inside a car.

The car AC compressor works as its name implies, it compresses and gives pressure to the refrigerant. Then, it sends the refrigerant to the condenser, which will lower the air temperature. It creates the cool air that comes out from the AC hole inside a car.

As you can see, if the car AC compressor doesn’t work, the AC system won’t get the refrigerant that works as the cooling element. Therefore, it is not surprising, if you face a problem with the air from AC, such as a car air conditioner blowing hot air.

Therefore, when you have a problem with the AC and take your car to the workshop, they will check the compressor first. If it doesn’t work, then this is the main culprit of the AC problem. Other than that, the leaking refrigerant or damaged condenser also could be the cause of a car air conditioner not blowing cold air.

The Symptoms of Car AC Compressor Problem

There are several signs you can notice for a car’s AC compressor that doesn’t work as it should be. By noticing these signs, you can fix the compressor as soon as possible before it causes the biggest problem. So, here are the symptoms of a problem that happens to the AC compressor, one of the essential parts of a car air conditioner.

         High Temperature of the Car Interior

A damaged or not-working AC compressor will make the AC system unable to create a cooling cycle involving refrigerant. That means the car AC system can’t produce cool air. Instead of cool air, the AC produces hot air because the air it sucks from the outside doesn’t get cooled down by refrigerant. Plus, it goes through the engine room, which has a high temperature.

You can feel the temperature inside your car gradually increase. Even though you have blasted on the AC, it is not getting cool. Instead, you feel it getting hotter.

This condition happens because of a broken compressor. However, the other two factors cause car AC to blow hot air instead of cold air. It could be a leaking refrigerant or a low level of refrigerant. You need to bring your car for repair or have a car air conditioner recharge.

         Noise from AC

The noise when you turn on the HVAC system of your car is normal. That is the sound of the system starting its process. However, when you switch the AC on and you hear a loud noise, different from normal noise that could be a sign of a damaged compressor.

A car compressor has several chambers with a sealed bearing that will turn around to provide pressure to the refrigerant. It should work smoothly to provide optimal performance. However, when one of the parts is broken or damaged, it will fall from its ideal size. Thus, when it turns on, it will hit the chamber wall and cause a loud noise.

You should replace the whole internal bearing to solve this problem. Do not keep it too long, otherwise, it will damage the whole compressor. Or, for safety and better value, we recommend changing the whole AC compressor. The new AC compressor will work well and last longer, which means you save more money on its maintenance.

         Car AC Smell Bad

Another symptom of a bad compressor is when a car air conditioner smells like chemicals. The smell comes from the forcefully compressed leaking refrigerant. When the compressor did that, it will spread the chemical smell on the entire AC system. It will affect the air that comes out from the AC.

It means that the problem is not only on your AC compressor that has too strong pressure. The leaking refrigerant also causes this problem, which requires more attention and repair. Some people deal with this problem by installing a car air freshener or deodorizer. Yes, that could cover the smell, but the chemical substance is still in the air and can cause a health problem.

Therefore, it is necessary to fix this problem as soon as possible for your driving safety. Fix the broken compressor and deal with the leaking refrigerant. Once you do that, the smell will go away and your car AC will work well without any problem.

         Car AC Produces Weak Cool Air

Your car AC still produces cool air. However, cool air volume and pressure are not as strong as they used to be. This also could be a sign of a bad car ac compressor, especially a problem with the compressor clutch.

The clutch keeps the compressor running and provides refrigerant pressure to flow it through to the AC system. It is the core of the entire AC system cycle. Therefore, when the clutch is broken, damaged, and not moving, it won’t produce the force that the AC system requires to create cool air. And, that weak cool air problem happens.

Ask for help from a mechanic to check your AC compressor. When they find its clutch has a problem, they will change it with the new one. Fortunately, you can ask for a new clutch part replacement only. That means you can save more money on your car air conditioner repair.

         Circuit Breaker Tripping

The circuit breaker tripping problem could also happen when the AC compressor doesn’t work properly. The cause of the tripping is overheating problems. Why does it happen?

The AC system will keep drawing power when the car ac compressor not turning on. It is necessary to produce more pressure than it needs to flow the refrigerant. Now, because after more power users and it can’t produce the cool air as it should, the AC system keeps drawing more power. That can cause the circuit to break.

The AC system will be turned off automatically. Thus, you can only use the car AC for a short time. Then, it doesn’t work anymore for a while until the power is stable.

Many people fix this problem by resetting the circuit breaker. You shouldn’t do that. That only makes it return to its previous condition and the problematic AC compressor is still there. It doesn’t fix anything.

When you use the car AC after you reset it, there is only one thing that could happen. It will trip again, which means you need to do the same on the AC system breaker. That shows that the breaker works well protecting your vehicle’s electric car air conditioner system from potential fire hazards. So, fix the AC compressor instead to stop this symptom from happening again.

         Suction Lines Problem

The broken AC compressor also can cause a blockage inside the suction lines. It could happen because it does provide enough power for moving the refrigerant. Thus, the accumulated refrigerant in one part will block the suction lines.

For this problem, you need to repair the AC compressor. The mechanic knows which part they must replace and fix to make the compressor work again. After that, you need to unblock the suction line. In most cases, you might not need to replace the section lines.

         Damaged Wire

You can only find this symptom when you regularly maintain and check every part of your car AC system. Therefore, we can say that this symptom can only be found by car owners with proper knowledge about car mechanics and such. If you only did standard maintenance, it will be hard to find the AC compressor damaged wire.

Of course, the damaged wire will affect the performance of the car compressor. So, at least one or two symptoms mentioned above will occur when you use the AC. So, without knowing the damaged wire, you can still detect that your car’s AC compressor has experienced some kind of problem. Visit the car workshop and let the mechanics have a thorough check to find the cause, and then fix it.

The Cost to Repair the Damaged Car AC Compressor

Depending on the condition, the cost of fixing your vehicle’s AC compressor is different. To replace the AC compressor, you must prepare at least $800 to $1,200. The actual price for a new AC compressor is around $650 to $1,000. You need to pay the labor fee for the mechanics for replacing and installing the new car AC compressor, which is starting from $150 to $200.

During the inspection, you might also find other problems, which come from the damaged AC compressor. For example, it can cause blockage and another critical situation with the car air conditioner condenser. That might cost you more, so prepare more budgets.

Of course, if you opt to replace the damaged part, such as the internal bearing part only, you might need a lesser budget than that. But, as we mentioned, replacing it with a new AC compressor is a better option. That will help you use the car AC system for much longer.  

Temporary Solution

Replacing the AC compressor with the new one is the best solution to deal with this problem. However, there are times when you have limited budgets to spend on replacing the compressor. As we explained above, the price to replace the AC compressor is somehow high.

What kind of temporary solution can you use? The answer is a portable car air conditioner. You can buy the portable AC for your car while preparing the budget for replacing the compressor.

The price for one unit of portable car AC is not that high. You can get a good one for just $30. There are the much better and expensive ones, which are around $100. It can work like your original car AC system and might be even better because of its portability feature.

Because it is a temporary solution, choose a high-quality portable AC for the car. For that reason, you should consider several factors before getting this moveable AC, such as:

         AC power – a high-power portable car AC is the best choice if you use a big-sized car, such as an SUV or another family car type. But, if you use a small-sized vehicle, choose one with enough power.

         Functions – currently, you can find various products of portable AC with different features. The standard one is the product with a cooling function. But, if you need more, you also can find the product with more functions, like heating, dehumidifier, and many more.

         Size – even though this car Air Conditioner is a portable product, it comes in various sizes. Choose one that fits with the interior of your car. Compact size is a good choice, but if you have a big vehicle, like an RV, you can use a bigger portable AC as it has more space where you can use it.

         Maintenance – choose the portable car AC with the easiest maintenance process. You don’t want to replace the filter for car air conditioner too often. Find one that has the best durability and is easy to maintain. After all, you will use your original car AC once you fix the AC compressor.


Car AC problems lower the driving and journey experience levels. Therefore, all car owners must solve the AC problem as soon as possible. Of course, if the problem is related to the AC compressor, you know how to deal with it. We hope you never have to deal with an annoying problem, like a car ac compressor not turning on. tin pan

A Guide to Identify and Solve the Car AC Blowing Hot Air Problem


A Guide to Identify and Solve the Car AC Blowing Hot Air Problem

You are driving in the middle of the hottest day of summer. Naturally, turn on the AC in your car to fight against the heat. But, what happened then? Instead of cold and fresh air, it blows hot air. This incident ruined your trip. You can’t enjoy it and it could be dangerous because it can lower your focus when driving. Why is car ac blowing hot air? This article will reveal everything about this car’s AC problem and the solution for them.

The Cause and Solution for Car AC Blowing Hot Air Problem

So, why is my car ac blowing hot air? Many factors can cause this car’s AC system problem, such as:

car ac blowing hot air problem

Leaking Car Refrigerant

A refrigerant is the core of the car AC system. This liquid circulates through the car’s AC system removing heat and humidity from inside the car. A car’s AC system can only work properly when it has proper refrigerant levels. Therefore, if it drops its level or decreases because of the leak, the AC system won’t work. Instead, the car AC system will bring in and blow out the hot air because it didn’t cool down by the refrigerant. And then, the car ac blowing hot air all of a sudden problem is happening.

It happens a lot on old cars or cars without proper maintenance. Mostly, it causes the problem, like car ac blowing hot air when stopped. When your car is in idle mode, the engine will increase the temperature of the air around it before entering the AC system. That’s because the hot air comes out from your car’s AC system.

SolutionHow to fix car ac blowing hot air because of the refrigerant leak? The first thing you should do is detect whether or not the leaking refrigerant is the cause of your car’s AC problem. Unfortunately, it is not easy to detect this problem. Most car owners don’t realize this because they miss one spot to see, which is under the car. You can easily spot this problem when you see a puddle of liquid under the car. That is one of many signs of a leaking refrigerant problem.

To fix this problem, simply bring your car to the car workshop. Let the expert repair car ac blowing hot air problem and diagnose your car AC system. In most cases, they will inject the dye liquid into the AC system to track the leak. They can find the location this way, then fix and patch the leak. After that, the car’s AC system will work properly, blowing in cold air like what you want.

Faulty Condenser

Another factor that causes the car ac blowing hot air problem is the faulty condenser. As mentioned earlier, the refrigerant will absorb the heat and humidity from the air the AC system bring in. But, it can’t work continuously because the temperature of the air affects the refrigerant. This is where the condenser shows its important role. The condenser will keep the refrigerant cool enough to do its job properly.  

When the condenser can’t work well, the problem will occur. Therefore, it is not surprising if you find the car ac blowing hot air after recharge problem. Even if you recharge the AC system, it still can’t work properly because it can’t cool down the refrigerant, so it keeps blowing hot air.

A faulty condenser also can happen because of dirt or debris. You can find this part in front of the car, right between the grille and the radiator. The condenser uses the airflow from the grille to help the cooling process. When something or debris blocks the condenser, it gets no air for cooling function. That makes it unable to cool down the refrigerant and causes a problem.

Solution: To identify this problem, look through the grille to see if there is any debris. Or, if the hot air problem occurs after you bump into something and bend the grille or fender, it also could be a sign of a faulty condenser. The solution is cleaning the condenser of debris. If it is damaged, you might need to replace it with a new condenser. Take it to the car workshop to get the new condenser. The car ac blowing hot air cost is not that expensive. It is around $150 to $300.

Broken Compressor

The compressor is responsible for circulating the coolant or refrigerant to the whole AS system and passing through the condenser to lower its temperature. So, if this part is broken, the refrigerant won’t be able to cool down the air. Thus, it causes the car ac blowing hot air when idle problem.

Why is this part broken? As usual, poor maintenance is the main culprit. However, it also could happen when you use no AC for a long time, such as in winter. Therefore, the latest car has a defrost mode that keeps the condenser and compressor active for the entire year.

Solution: How to identify that your car has a broken compressor problem? There are two signs you can notice, which are car ac blowing hot air and making noise. In some cases, it can cause the car ac blowing hot air on driver side problem. It means that part has the worst problem because of the broken compressor.

The solution is replacing the compressor with the newest one with better durability. You can fix it, but it will break easily, which costs you more money to fix it. It would be better to replace it with the new one that works for a longer time.


Those three are the common cause of the hot air problem in the car’s AC system. Other factors also cause this problem, like electrical system problems, broken cooling fans, and more. You can find more accurate information by asking for help from the expert at the car workshop. That is everything you need to know about the cause and solution of car ac blowing hot air problem. tinpan

Car AC Stops Working When Hot Outside: Causes and Solutions!


An absolute horror if you have to drive your car on a hot day and the air conditioning stops working or doesn’t cool the car off enough. We are confident that you won’t want to drive while the engine is heating up and continuously pushing hot air into your car while the temperature outside approaches 100 degrees.

These are the reasons why you need to track down those responsible for any AC-related issues. What are the reasons why your car’s air conditioning stops functioning when it’s hot outside, and how can you fix it? Let’s read the article together and discover the truth!

Why Car AC Fails When It’s Hot Outside

A car’s air conditioner is either not cool or only sometimes cool.

One of the most typical issues is when it is hot outside. This indicates that there are issues with the car’s air conditioning system. To prevent the problem from getting worse, shortening the lifespan of numerous crucial components, increasing fuel consumption, and degrading your driving experience, the reason must be identified and handled quickly.

When traveling in hot weather, your air conditioner may encounter any of the following issues:

  • Poorly functioning air conditioning system: This is when the air conditioner is on full blast, but you still don’t feel cool while driving, and there may also be times when the air leaving the cabin smells unpleasant.
  • Even if the cooling system has been turned on, the air conditioner loses its ability to cool entirely in this situation.

7 Reasons Why Your Car’s AC Is Not Working Well in Hot Weather

When it’s hot outside, your car’s air conditioning may cease working for a variety of reasons, including the following:

Clogged filter

A blocked air conditioner filter is frequently one of the reasons why the air conditioner stops operating or keeps running but does not provide adequate cooling.

A Dirty Outdoor Unit

The outside unit is often mounted in front of the engine fan and radiator. This component serves as a heat exchanger, dissipator, and heat discharger. Too much dirt buildup on the component may result in poor heat dissipation, which can significantly reduce cooling effectiveness and render your AC inoperable.

Blocked Condenser

The condenser’s job is to transform Freon gas into liquid form. It takes place during a heat exchange procedure in which the refrigerant’s heat is forced out and exchanged with ambient air. The refrigerant will cease flowing if the condenser is broken, which will stop the flow of cool air.

Refrigerant Problem

Your AC system has a gas shortage since it hasn’t had a gas refill in a while. The air conditioner will work inefficiently as a result of this circumstance and won’t pump cool air into your car.

A refrigerant gas leak is also a scenario that might cause your air conditioner to stop working. The AC system will stop functioning when the pressure falls below the normal range.

AC Lines Freezing Up

The inside unit is in charge of absorbing and lowering the air’s temperature as it passes through. But with time, this area becomes dusty, conducive to the growth of germs and mold, and emits foul aromas. Over time, the interior unit will get frozen, with thick ice adhering to the louvers and holes and restricting airflow.

Faulty Electrical Systems

The circuit is in charge of regulating the functioning of the whole system; if the circuit or other electrical parts fail, the air conditioner will not function. Users should thus examine the circuit, the capacitor, and other components to determine the precise cause.

Problem with Cooling Fan

Your car’s air conditioning system may stop working when it’s hot outside for a variety of reasons, one of which is a cooling fan issue. The following factors might be at blame if the blower is turned on but is weak or not cool: shorted-circuit fan motor, defective capacitor, harmed contactor coil, or damaged electrical circuit

What to Do If Your Car AC Fails In Hot Weather?

Here are some things you can do if the case happen.

Clean and Change the Air Conditioner’s Regularly

Filters that are dirty will restrict the flow of air, which will impede the air conditioner’s ability to cool. Users should thus be mindful of routine cleaning to guarantee efficient device performance. Drivers may think about changing the air filter with a new one if there is an excessive buildup of dirt.

Based on operational circumstances and manufacturer guidelines, the replacement interval should be determined. Typically, car owners should change their air filter with a new one after 16,000 to 24,000 kilometers.

Drive Less in Hot Weather

You should avoid driving during the warmest parts of the day while it’s hot outdoors to save your AC system from stress.

Check The Whole AC System

Drivers should bring their cars to a dealer so that a specialist may examine every component and determine the problem’s root, fixing the issue that causes the car’s air conditioning to malfunction in hot weather.

To guarantee that the device’s operability is restored, the interior components also require a thorough cleaning. If a broken compressor is the root of your air conditioner’s inability to cool, you must fix or replace it. The kind of car and the air conditioner compressor’s manufacturer determine how much it will cost to replace the old one.

Routine Maintenance

An essential treatment for the condition of the car air conditioner not cooling is routine maintenance, particularly when the vehicle must frequently operate in a dusty area. Once a year, drivers should do maintenance on it to inspect and repair any damage.

Things you Need to Know About Car Air Conditioner


Do you know your Car Air Conditioner Components? Here is the Basic Guide for You

Things you Need to Know About Car Air Conditioner

No one wanted long hours of a road trip without an air conditioner. It is one of the car’s crucial parts. You might have felt and experienced a bigger air conditioner in your house or office. The car air conditioner works pretty much the same. Today we are going to cover the basics of a car air conditioner. Including the important elements and how it works.

Air Conditioner System

Air conditioner commonly works by converting high-pressure Freon gas to a high-pressure liquid that could be cooled down and then distributed to the car’s cabin. It consists of several elements, just like the regular air conditioner in your house. Each element works hand in hand to produce cool air. 

Air Conditioner Components


An air conditioner wouldn’t work without its main element, the refrigerant. Also known as Freon, this element carries heat from inside the cabin and delivers it outside. It is the element that will change states from gas to liquid and back to gas throughout the cooling system. It will first absorb heat inside the car and then the heat is pushed outside. Then it will change back to the gas form and travel back inside to repeat the cooling process. This process results in the cool wind you feel in the car’s cabin.


The first in the line of the air conditioner is the compressor. Compressor’s principle uses a combination of Boyle’s, Charles’, and Gay Lussac’s gas law. It will pressurize the refrigerant and therefore raise the temperature. Firstly it will squeeze the gas tightly together. The reason is to get the refrigerant’s temperature higher than the outside temperature. It’s important because we know that temperature flows from hotter to cold places. If your car ac compressor not turning on or what causes ac compressor to not turn on, guarantee the rest will not work either.


The condenser is located in the front part of the car. You can pop the hood and see this component standing in front of the car’s radiator. It is the opposite of the evaporator. While the evaporator stores cold refrigerant, the condenser is in charge of storing the hot refrigerant. That’s why it is located in front of the radiator to facilitate heat transfer to the outside environment. It is also a part of the air conditioner that breaks easily because of the location in the car.

Expansion Valve

Before the refrigerant passes to the evaporator, it is cooled down in the expansion valve. It depressurized the liquid to also decrease the temperature. This component also controls the amount of refrigerant that goes into the evaporator. With an expansion valve, the car air conditioner could transform the liquid state of a refrigerant to vapor that will be managed by the evaporator.


The evaporator is the one that picks up heat from inside your cabin to transform it into cool air. It will depressurize the liquid refrigerant from the expansion valve and absorb heat. Again, it uses the principle of the second law of thermodynamics. This component also relies on the blower, which just as the name stated, will help blow air over the evaporator. As the refrigerant absorbs heat, it then forms a vapor.

That is all you need to know about a car air conditioner. This basic knowledge can help you to determine if there is a leak or damage in your car’s air conditioner system. It also helps you to communicate with the technician in an auto shop so they can fix the problem quickly for you. Knowing these is also important so you can check them up before going on a road trip. Always make sure to do a periodical check-up to keep your air conditioner system working well.

5 Tips On How To Keep Your Car air Conditioner Stay Longer And Cool


In this article, we’ll show you how to take care of your car air conditioner to keep it cool.If your air conditioner is working optimally, it can reduce the temperature in your car or interior.

Keeping Your Car’s Air-Conditioning Cool – In this article, we’ll show you how to take care of your car air conditioner to keep it cool.If your air conditioner is working optimally, it can reduce the temperature in your car or interior. 

Therefore, drivers and passengers can feel comfortable during the trip. Of course, a properly functioning air conditioner is very necessary, especially when using a car in a hot city.

Also, you should know that the car air conditioner also plays an important role during the rainy season. When it rains, the windshield fogs up due to the temperature difference between the inside and outside of the car. 

Therefore, to overcome this, drivers are advised to keep the air conditioning on. Therefore, the dew naturally disappears, and the driver’s visibility is improved.

Given that air conditioners have important functions and roles, car owners should know how to properly care for their car air conditioners. Here, we provide the information.

Tips To Keep Your Air Car Conditioner Cool

1. Keep your car clean

Regardless of the type of vehicle used, maintaining cabin cleanliness is a must for any vehicle owner. If the inside of the car is dirty, dust will get into the AC filter, the AC car compressor not turning on – car ac compressor won’t kick on and it will not work as well. This makes it difficult to feel cool inside the car even with the air conditioner on.

2. Do not open the car window with the air conditioner on

The next way to care for your air conditioner is to avoid opening the windows when the air conditioner is on. It must be remembered that car air conditioners are not designed to cool large rooms. 

Opening your car windows will improve the performance of your air conditioner. In addition, dust and dirt fly and enter the air conditioner filter, which may adversely affect the performance of the air conditioner.

3. Please refrain from smoking in the car

For some people, smoking in the car becomes necessary for certain reasons, such as getting rid of boredom or drowsiness. However, this should be avoided.

Smoking in a car not only leaves an unpleasant odor in the car but also pollutes the air conditioning circulation with smoke. Cigarette smoke can enter and settle in the air conditioning circulation system. As a result, the air coming out of the air conditioner is contaminated with nicotine.

In addition, cigarette smoke may adhere to the evaporator of the air conditioner, which may reduce its effectiveness. An AC evaporator, also known as a refrigeration unit, serves to evacuate cold air from inside the vehicle. If the evaporator breaks, you will feel hot air in the cabin.

4. Regularly clean the air conditioner condenser

Alternating currents contain different components. One of them is a capacitor. As the name suggests, AC condensers convert high-pressure gases (freons) into condensate or liquid. If you want your car air conditioner to last longer and stay cool, you need to perform regular maintenance on this AC condenser.

5. Keep the cabin filter clean

A cabin filter is an air filter located inside the vehicle. On Japanese or Korean-made cars, this cabin filter is usually mounted on the AC system blower and is located behind the dashboard tray.

Basically, the function of this filter is to prevent dust and dirt from entering the evaporator. Therefore, the cabin filter should also be kept clean.

However, this cabin filter usually becomes dirty over time. If conditions are not very favorable, the cabin filter should also be replaced so that the air conditioner can work optimally and cool the cabin space.

These are some ways you can take care of your car air conditioner. With a well-maintained, it will last longer. You and other passengers can feel the cool air while driving, so you can feel more comfortable.

Get to Know Parts of a Car Air Conditioner


Get to Know Parts of a Car Air Conditioner

It is always important to know the parts of a car air conditioner. Naturally because by knowing all the parts, you can do a little inspection in case of damage. We all know that an air conditioner works to convert refrigerant into cool air that blows into your car cabin. Having a long trip without a well-working car air conditioner is surely uncomfortable. Here are all the parts that you need to recognize in your car air conditioner.

Do you know all the Parts of a Car air conditioner? Get to know them so you can easily spot Damage in the Future

  1. Compressor

The compressor is the first on the line. It works to pump and distribute Freon to other parts of the air conditioner system in the car. When it is first distributed, it will be in the form of high-pressure gas. Besides the compressor, there is also a compressor clutch. If the compressor itself is connected to the crankshaft, then the clutch is the one providing the electricity that drives the compressor.

When a car AC compressor not turning on – auto ac compressor not turning on, it is most likely that there is a problem with the electric system. The magnetic spool in the compressor clutch could be malfunctioning, so the compressor can’t suck in any Freon and deliver it to other parts.

  1. Condenser

After getting the high-pressure Freon gas, the condenser will transform this gas into a high-pressure liquid. The condenser pipe is curved and equipped with fins. It is also equipped with a fan to help the heat absorption process. All of these parts need to be cleaned periodically so that they can work smoothly all the time. 

  1. Pressure Switch

If you think that the car air conditioner doesn’t have a safety function, then you are completely wrong. The pressure switch controls

the work of the compressor by adjusting the performance of Freon gas. Inside it is a liquid sensor that works automatically according to Freon’s gas pressure and engine temperature.

  1. Filter Drier

Dirt and dust are inevitable. That’s why you got a filter drier as one of the parts of a car air conditioner. Its main objective is to filter dirt, dust, and even water that the Freon carried all the way from the compressor. Any water should immediately be removed since it could freeze inside the expansion pipe and create a problem for the AC system. It is also a temporary storage for liquid Freon.

  1. Evaporator

Evaporator works to absorb additional heat that the Freon carries while passing through the expansion valve. Among other components of car air conditioners, an evaporator is most likely to have a leakage problem.

  1. Ventilation Blower

Located under the car’s dashboard and in the top middle of the car’s cabin, this component works to blow Freon and air throughout the car cabin. To keep your air conditioner always cold, you need to clean this part often. Easily take a brush and brush off any dirt.

  1. Expansion Valve

The last component of a car air conditioner is the expansion valve. It will change back the liquid Freon to its initial form, which is gas. It also helps regulate the amount of Freon that flows. It is a small channel between the filter dryer and the evaporator.

That is all the parts of a car air conditioner. Now you know whom to blame if your car air conditioner is not working properly. All of these components work in sync to produce cool wind that blows throughout the car. You can easily tell if one component broke down, it will affect the others. Most of the time you could tell by hearing the sounds or by the hot air instead of the cool wind.

How to Maintain Car Air Conditioner Condenser


Want to take good care of your car air conditioner system? Here are all the things you need to know to maintain your car air conditioner condenser.

How to Maintain Car Air Conditioner Condenser

The air conditioner is a crucial element of a car. It is composed of many components that have their own job to blow cool wind throughout the cabin. We all know the air conditioner system works by converting high-pressure gas to high-pressure liquid. It then gets streamed to the Receiver dryer and continues its journey to the expansion valve. One of AC’s many components is the car air conditioner condenser.

Condenser Function

The main function of a condenser is to lower the temperature of the refrigerant. The refrigerant is first pumped by the air conditioner compressor. Condenser works to absorb heat in the Freon that has been compressed from the gas form into liquid form.

If you are wondering where this component is located, open up the hood of your car. Commonly, you can see it in the front of the car radiator. This position is risky especially since a dirty condenser could affect the cooling process heavily.

What Broke the Condenser?

From now on, you might want to drive more carefully. Car air conditioner condenser could easily leak from something very minor, such as dust and gravel. It might also be caused by bouncing pebbles if you drive too fast on the highway.

Another thing that could break the condenser comes from inside the condenser itself, naming slow fan rotation as one of the causes condensers can’t work properly. It is because the AC is used too frequently or could be on a long road trip where your car doesn’t even take a break. You also want to pay attention when you are filling out the Freon. Too much Freon can trigger excessive pressure. This means it can raise the room temperature and the condenser can’t produce cool wind because it’s warmer than normal.

Maintaining Air Conditioner Condenser

Now that you know this element breaks easily, you want to pay more attention. If your condenser is not working, it could also be because the car AC compressor not turning on ( car ac compressor not coming on ). If that’s the case, you might want to look up the whole AC system and get it fixed. But here’s how you could maintain the air conditioner condenser from damage.

Routine Check-ups

The first thing that might work is if you do routine check-ups. Every 3 or 6 months, take your car to the auto shop for a quick check-up. You could relay to the mechanic if you have any problems with the air conditioner and they will gladly check it for you.

DIY Clean-up

Another thing that you can easily do at home is to clean the condenser by yourself. First, you need to make sure that the car is not recently used. Make sure the engine is cooled down enough before the cleaning process. Then, you can uninstall the front bumper of your car. Open the hood first to locate all of the screws and bolts you need to remove. Before you move on to the next step, cover other engines with a trash bag to avoid them from getting contaminated.

The easiest way to clean the condenser is to brush off the dirt. For this process, you could use a clean brush or even a vacuum with a brush attachment. Then, you will need to spray a coil cleaner, followed by a rinsing process, and drying the condenser completely dry. You can use tools like a blowgun to fasten the drying process.

That is everything you need to know about the car air conditioner condenser. It is one of the AC elements that produces cool air in your car. You can do a periodical check-up to make sure it is still working fine.

How Electric Car Air Conditioner Works?


Electric automobile manufacturers are extending the brand-new generation beyond electric-powered vehicles with exciting factors to improve an electric car air conditioner and climate control structures.

How Electric Car Air Conditioner Works?

If you want to ask from a technical point of view, the most critical element is the overall performance of electrical automobiles as compared to standard motors. For instance, inside the case of an electric car air conditioner, when shopping for an electric powered vehicle with air conditioning, the buyer thinks about the reliability and toughness of the electric car.

One of the drawbacks of electrical cars is that it can be tough to maintain the battery at its most reliable temperature while the air conditioner is running at full capacity. 

In this article, we can speak about how an electric car air conditioner works in electric automobiles and other thrilling information, in contrast to traditional cars that electricity HVAC systems, electric powered cars perform in a very one-of-a-kind way. 

Given that an electric car has a motor, the AC’s ability to deliver energy is determined by the amount of stored battery strength. Since electric motors are the future, they need to have the same skills as traditional cars. Of course, the air conditioning system is one of them. 

Strictly speaking, if the manufacturers want to sell those cars for a long time, they need to have proper features like electric air conditioning and internal combustion engines with air conditioning and heating. However, have you ever questioned how an electric vehicle ought to reap this functionality?

A Simple Factor

There are several factors to not forget when designing an electric car air conditioning device. The main issue with an air conditioning gadget is the electricity supply. In terms of source, internal combustion engines range from electric powered cars. 

Take Tesla as an instance; this vehicle is leading while electric automobiles take care of air compressors. This compressor may be very similar to a home refrigerator that makes use of 400 volts of electricity. 

The compressor draws its operating strength from the automobile’s power storage system. At the same time, electric motors use compressors to push refrigerant through the cooling unit, cooling the air before it absolutely reaches the vents. Isn’t it always clean?

How Does Heater Work in EVs?

This is a truly critical problem to talk about. It’s very clean for the heating gadget to draw heat from the cooling gadget. However, it conducts heat to the engine. For Tesla, an electric heater replaces the heater array. Tesla says they use percent warmers to prevent it from extracting an excessive amount of energy from his electricity storage gadget. It really works as a resistor that increases the strength of resistance and increases the quantity of heat.

The Essential Part

Operating battery packs at the lowest possible temperature to enhance life and performance is another troublesome aspect of electric cars. That is why Tesla uses a pump that sends the antifreeze mixture around the EES, forming a separate cooling device. 

That is how the complete method works to minimize the temperature difference between cells in a battery PC. So simple, isn’t it?

AC Compressors For electric and Hybrid Vehicles 

Hybrid and electric motors have used electric-powered air conditioning compressors for over 15 years, it will be bad if my car ac compressor won’t turn oncar AC compressor not turning on. People are typically wondering if both cars have engines with air-conditioning compressors that work correctly. The air-conditioning device includes three phases: an electric compressor, a 3-phase inverter unit, and a related management system.


Electric automobile manufacturers are extending the brand-new generation beyond electric-powered vehicles with exciting factors to improve an electric car air conditioner and climate control structures. A lot of these measures cause “reduced gasoline intake and associated air pollutants.” It could sound cliché, but when electric cars are round, they’re surely electric powered! call for is not likely to be exchanged.

Why Car Air Conditioner Smells Like Chemicals?


Have you ever been bothered by the smell of your car’s air conditioner? This can happen to cars that have been in use for many years. To deal with a car air conditioner smells like chemicals, you first need to understand the possible causes.

There are many factors that cause Car Air Conditioner Smells like Chemicals. There are a Number of Reasons Why a car smells bad immediately after Turning On the Air Conditioner

Unpleasant odors emanating from air conditioners can vary from car to car. This depends on the odor-causing agent.

7 Causes of Car Air Conditioner Smells Like Chemicals

There are many factors that cause car air conditioner smells like chemicals. There are a number of reasons why a car smells bad immediately after turning on the air conditioner.

  1. The cause of the smell is running out of freon gas

Fluorocarbons are compounds that are often used in air conditioners, including automobile air conditioners. If you use it for a long time, the freon in the car air conditioner may decrease.

Low freon causes car air conditioners to smell musty. This condition is usually followed by other symptoms, such as an air conditioner not cooling.

  1. Odor due to mold growth in the evaporator

The evaporator is the part of the car’s air conditioning system that absorbs heat from the air to reduce the heat inside the car. If mold forms in the evaporator, it may produce a foul odor.

Because the evaporator of the car air conditioner is damp, it will grow mold. Moisture is created because the steam exhaled by the air conditioner can stick to the evaporator.

In particular, mold is the cause of unpleasant odors in car air conditioners. When you start your car engine, it usually smells like urine.

  1. The smell is due to a damaged gas tank

A foul odor coming from your car’s air conditioner may be the smell of gasoline. If you can smell gasoline from your car’s air conditioner, the gas tank may be damaged.

For example, if the gas tank cap is loose, the liquid will come out easily and you will smell gasoline. When the car is running, the smell of gasoline becomes more noticeable, and the smell may spread to the air conditioner inside the car.

This gasoline smell can also be caused by a gasoline leak inside the car. This usually happens after the car is taken to a mechanic and the technician accidentally spills gas inside the car.

  1. Smell of car air conditioner due to exhaust gas

I’ve also smelled the exhaust fumes from my car’s air conditioner. This usually happens when driving near a truck or other vehicle that emits a lot of smoke. It can be worse if an ac compressor not turning on – car air conditioner compressor not turning on.

Exhaust gases emitted by vehicles can expose vehicle components. As a result, the odor enters the freezer and causes a bad odor in the car’s air conditioner.

  1. Your car’s air conditioner overheats and smells burnt

Long-term use may cause the car’s AC motor to overheat. It will cause an unpleasant burning smell.

Excessive temperature conditions will damage compressor oil. If you don’t change the compressor oil soon, the burnt smell will get worse.

  1. The sour smell of old car perfume

An unpleasant sour smell may come from the car air conditioner. There are various causes of car air conditioner odors, one of which is old perfume. Car perfume works on odors in the car. However, long-term use of perfume can make it smell bad.

In addition, the sour smell can also be caused by dirt in the cabin. Dust and debris stuck in the car also affect the unpleasant odor of the car air conditioner.

  1. Smell of rat urine and carrion caused by feces

Dirt that builds up in your car not only smells like smoke, but it can also cause the air conditioner to smell like rotten meat and mouse urine.

If you smell like this, don’t panic. The smell of rotting meat or rat urine doesn’t necessarily mean that rats are hiding in your car. A car air conditioner smells like chemicals can happen, especially if the interior and engine are very dirty.

The Reasons for Choosing a Filter for Car Air Conditioners

This cabin filter is risky and dirty due to the dust. The effect makes circulation disturbed and a car ac compressor not turning on – ac compressor not working car due to the exposure to pollutants. A dirty air conditioner filter causes the filter substitute. A dirty cabin filter is often out of the attention in which it is risky to disturb comfort and health. In addition, a dirty cabin also disturbs an air conditioner’s performance. It is suggested to consider a car cabin condition and change it routinely. A cabin filter is ideally changed when it reaches 10 to 15 thousand kilometers. The time interval is also recommended if you move through dusty terrain. Of course, it is not something absolute. Some car manufacturers generally use a cleanable cabin feature before you change it with a new one. 

The Recommendation of A Filter for a Car Air Conditioner

When a pandemic happens, health is an essential thing. Furthermore, if you drive your car, it is the main thing. Some component manufacturers and accessories penetrate by changing a hygienic air conditioner feature. You must select the most recommended one. You can select the best of a filter for a car air conditioner in the market. You can select a filter filtering 98% of dust particles, pollutants, bacteria, and viruses from outside of the vehicle. An active carbon layer absorbs and neutralizes a pollutant and odor when you use the vehicle. In addition, the substitute and treatment of the cabin filter are so easy. The owner can do it without a technician when you have spent 10 kilometers. 

The Functions and Signs to Change Your Filter for Air Conditioner

Talking about a car air conditioner system makes the vehicle owner understand well the most crucial part of the current component. It is a filter for the air conditioner. An air conditioner is an essential part of the car, especially using it to drive in hot weather. For some people, a filter is an unfamiliar term. The components have an essential role in your driving comfort. You can benefit from car insurance to handle repair costs. Furthermore, keeping the drivers’ health and passengers’ is crucial. You must maintain the functions of the air conditioner. 

Functions of A Filter for Air Conditioner

Car Air Conditioner Recharge, The Easy Ways to Do It in Just 15 Minutes!


There are 5 Easy and Fast ways that you can use if you want to do a Car Air Conditioner Recharge

If you use AC in your car, you must have felt that the air conditioning system in your car is not cold anymore. So, if that happens, then that’s a sign that you have to do car air conditioner recharge.

To make it easier for you to recharge your car air conditioner, here we provide the easy ways. Don’t worry, you only need 15 minutes to do that!

First, You Need to Prepare All The Equipment

You have to buy a kit for charging your car. If you don’t know what kind of tool kit you should buy, you can ask your auto parts store to get the right recommendations.

If your car is a 1995 car, the off-the-shelf AC that is usually used is R-134. If your car was produced in 1992-1995 then usually the AC used is AC type R-12 or R-134. However, if your car is still using AC R-12, you actually need to replace it with R-134. 

In addition to the refill kit, you will also need one or more cans of coolant. Generally, we need two cans of AC refrigerant if we want to refill it.

Then, how much does it cost to buy all the equipment? To buy the complete kit, you need to pay $30 per can and $55 for two cans.

We suggest looking for a filling kit that comes with UV dye. That will help you find leaks in your car’s air conditioner.

Once Your Equipment is Available, Look for Ports on The Lower Side

The second step in doing a car air conditioner recharge is to look for the underside of the car air conditioner. The shape is like a thorn which is located between the compressor and the evaporator.

Then, Install The AC Can

After finding the underside of the AC, now is the time for you to attach the dispenser hose and connect it to the AC can. Attach it to the underside by pulling the slip ring outwards. Then, push and release the ring again.

After that, you have to turn on the AC machine and check the gauge system. The compressor clutch must also be engaged and parts of the compressor must also rotate.

So, if the pressure gets lower than 20 psi and the compressor isn’t running, then remove the AC refrigerant until your car’s clutch can work. You have to shake the can first before doing it. Shaking also needs to be done every 3 to 4 seconds thereafter.

Next, Proceed with Charging The Coolant

After the previous steps you did, now you have to check the pressure section in the refrigerant to find out the appropriate system pressure. Next, remove the refrigerant. Then, check the pressure until it reaches the pressure level you want.

On some people, at 85 degrees, the system requests pressure between 45-55 psi. So, you can’t put too much pressure on it. Start by applying pressure slowly.

If the can starts to get empty, turn the can over immediately so that the remaining oil can be completely removed. After that, remove the can.

You Also Have to Check for Small Leaks that Occur in Your Car’s AC System

We have already advised you to buy a kit that has a UV dye. So, use this UV dye to detect small leaks that might occur in your car’s AC system.

The trick is to use a UV pen and check every valve or connection point in the car’s AC system. In some cases, there are small leaks. That spot is what makes the front air conditioner flow refrigerant to the rear air conditioner which is under the car.

Those are the ways to do car air conditioner recharge. However, if you are still having trouble doing the methods above, you should immediately contact the nearest repair shop or spare parts store. They will not only help you with car AC leaks, but also various other AC problems such as the ac compressor in car not working –  car AC compressor not turning on.

Car Air Conditioner Repair: What Things You Should Know Before Talking To Your Mechanic


Car Air Conditioner Repair – If you’ve been stuck in a never-ending line of traffic on a hot sunny day without your car’s air conditioning, you’ll understand the importance of a functional car air conditioning system. However, unlike many simple repairs, car air conditioning repairs can frequently be costly. If something goes wrong, knowing your car’s air conditioning system will help you understand the severity of the problem when speaking with your mechanic, potentially saving you funds on the maintenance.

Car Air Conditioner Repair: What Things You Should Know Before Talking To Your Mechanic

This guide will look at what might be causing the issue and how to talk to your mechanic about it.

AC Compressor Issues

There are numerous possibilities for problems with the air conditioning system, but by correctly identifying the source of the problem, we can narrow down the possible causes. If your AC is not as cool as it used to be or starts cold but later gets warmer, the problem could be in the car AC compressor.

The serpentine belt powers the AC compressor, which means it has a pulley to transfer that power into the unit. Because the air conditioner does not need to be on all of the time, the compressor has a clutch that allows the pulley to turn freely without actually powering the unit.

When the air conditioning is turned on, the electromagnetic compressor clutch receives a signal to engage. The part mounted on the compressor generates a magnetic current that attracts the outer clutch disc. The disc then joins the compressor shaft, and the pulley starts shifting power to the compressor.

Look at the compressor pulley and the clutch disc – if both are rotating, the clutch is working properly and the compressor is holding power. If the pulley spins while the clutch disc remains stationary, the clutch isn’t functioning correctly.

The problems with the car AC compressor not turning on ( ac doesn’t work in car ) can be traced back to the clutch compressor and an electrical problem.

Begin with the simplest causes, such as fuses and relays, and start working your way up to the clutch itself. Keep in mind that to work on the compressor or clutch, you must first safely drain the refrigerant from the system – a task best left to a mechanic equipped with professional tools.

Weak Airflow in the car AC

We fully understand your suffering as a result of poor airflow. The sweat alone would be sufficient to move any of us uncomfortable. However, there are several factors at play. If you start noticing reduction of airflow sooner on, take the appropriate action and have it checked out. take the appropriate action and have it checked out before other potentially fatal car air conditioner repair occurs.

Fungus or mold spores may have grown in the evaporator core as a result of evaporation of water during the cooling process. When this occurs, air will have difficulty in reaching your air duct. Secondly, the hose has become detached. This is most commonly seen with the blower hose, which supplies air to the blower unit. Whichever the source of your airflow issues, we have a solution. Try to schedule an AC Performance Inspection.

Smelly Odor from The AC Vents

You appear to have an odor problem on your hands. This car air conditioner repair issue could be caused by many factors.

Possible causes of this issue are the air cabin filter starting to age and filthy or the evaporator case being moldy. 

A common issue for many vehicles is when water accumulates in the evaporator case due to a clogged drain. Mold will build up.

Moisture and age can cause a leak in your AC. Simple as that. Sealants and nozzles can also lose elasticity and tear down with time, enabling refrigerant to flee and evaporation of water to reach your car’s air conditioning system. Humidity is the root cause of air conditioning system failure, combining with refrigerant to form corrosive acid that damages the system.

Signs You Need to Switch to Portable Car Air Conditioner


What is a Car Without a Cooling System? 

If you are wondering if it is time to invest in a portable car air conditioner, you might want to consider these factors. We all know that the air conditioner in a car plays a big role. It is an element that makes our road trip bearable and not noisy because we can close the windows all the way up. Just like the entire element of the car, you might need to inspect the AC every now and then.

If your car’s AC system broke down, the alternative is to get a Portable Car Air Conditioner.

 If you are not familiar with the air conditioner system, you might think that it is a tool that creates cool wind. When in fact, it transforms hot air through a complicated thermodynamics process to change the temperature in the car. The main character of this process is the car’s compressor.

How Does the Car Compressor Work?

Just like in a regular air conditioner, the compressor works by pumping high-pressure and high-temperature refrigerant to the condenser in front of the radiator. This process will then condense the refrigerant to a cooler temperature which is how you get a cool wind from the AC in your cabin.

However, if your car ac compressor not turning on, it might be caused by several things. Here are signs that your compressor is not working and you need to look for a cooling alternative ASAP before you become a sitting duck from the heat inside your car.

  1. Odd Sounds

The first telltale of a broken car compressor is odd sounds. If you hear it when you first turn on the AC, it’s most likely that the compressor is broken. This part will grind with other parts and whine if activated. This can also mean that the bearings are going bad. One thing you can do to make sure is turn off the AC and turn it back on. If the sounds only appear when the AC is on, then you’ve got an AC problem.

  1. Hot Air

The point of turning on your AC is to get cool wind going through the car. However, if all you get is hot air, you might need to look up the compressor. It means that the compressor isn’t doing its job to pump the refrigerant that can cool the air, or it can also mean refrigerant leaks in your AC system. When that happens, your choices are to go to the auto shop or start browsing for a portable air conditioner.

Portable Air Conditioner

When you get all those signs, you might want to start to look up the portable car air conditioner. Here are the benefits that you can get if you own one of these versatile tools.

The first benefit is the compact size of this portable air conditioner. This makes it not only perfect for small spaces such as cars, but you can also use it in your room back in the house. Not to mention that it uses a smaller portion of energy compared to traditional air conditioners and also window fans. It is also easy to clean and move around hence the small size. To add a cherry on top, different brands also include features such as fans, humidifiers, and dehumidifiers. 

That is all about your car’s AC system. Most of the time it is fixable, but if one day your AC compressor starts going bad, you need to have an alternative for cooling down your long trip across the city. When that happens, you can try getting a portable car air conditioner that has a lot of benefits. It doesn’t always have to stay in your car because you can take it anywhere with you after you finish using it in the car.

Car AC Blowing Hot Air when Stopped


Car AC Blowing Hot Air when Stopped

AC air temperature should be the same while running or stopping. It seems there is something wrong with your car AC blowing hot air when stopped. Some car owners experienced this issue, such as when at the red light. So, what should you do when your car AC blowing hot air (my car ac is only blowing hot air) at the red light or while parking it? 

The Car AC Mechanism while the Car Stop 

There is a component known as a condenser in the car AC. It is a heat exchanger in front of the radiator that maintains airflow. The function is the same whether the car is stopped while the engine is on or completely stopped.

car ac blowing hot air when stopped

Your car AC will blow cold air as your setting if the condenser is in normal condition. There is also another component known as a refrigerant charge. It helps to keep the air temperature cold as it does. 

Car AC also has a compressor clutch. The compressor has to run anytime you turn the AC system on. If it is not, it can be one of the causes why your car AC blowing hot air when stopped.  

The Reasons Why Car AC Blowing Hot Air when Stopped 

The first possibility is because the condenser doesn’t work properly. This component works to maintain the airflow. Indeed, there will be something wrong with the airflow if it doesn’t work. The air temperature will be hotter than the setting. 

This condition can also happen because of the low level of the refrigerant charge. Since the function is to control the temperature, you should keep the refrigerant at the standard level. Leaving the refrigerant without regular maintenance affects the air temperature of the car AC system. 

At a certain point, the refrigerant is empty and your car AC starts blowing hot air whether when driving or parking it. It is also because the compressor clutch is not cycling. 

In this condition, the condenser is often blocked by dirt or debris. That’s why you should maintain your car AC system regularly, including cleaning it of debris or dirt.

In case you don’t have any experience or skill, and experience, call a professional mechanic to diagnose the problem. One thing is for sure, you finally know why your car AC blowing hot air when stopped

The earlier you know the problem, the better. The repair cost is more affordable. This information may trigger you to maintain your car AC system regularly to prevent the same problem in the future.

Letting a small problem for so long will affect other components. As a result, you have to spend more money or even replace the AC system. Check the details below to get your AC system back to normal.

car ac blowing hot air on driver side

Check the Temperature Setting 

The temperature setting is one of the reasons why the AC blows hot air on the driver’s side and cold on one side. If so, you only have to adjust the AC temperature setting on the driver’s side to achieve the preferred degree. The problem is solved if there are no other issues in the AC system. You should check the AC components if this simple trick doesn’t work to make the AC air in the driver’s side back to normal. 

Reset the HVAC Control Module Program

Car AC blowing hot air on the driver side can also be because of an error in the HVAC control module program. This problem often happens after disconnecting the battery. The sign to check the module is when it shows inaccurate data. 

Inaccurate data leads to an inaccurate temperature. It is time to recalibrate the module. All you have to do is disconnect the negative terminal on the battery. Let it off for about 5 minutes. 

Now, turn the key on. Remember! You are not allowed to touch any HVAC controls after turning the key on. The module will reset and back to normal, and so does the AC temperature on the driver side. 

Check the Blend Door Actuator 

Malfunctioning on the blend door actuator can also change the AC temperature. It is known as a faulty blend door actuator. It is a condition when the actuator fails to do a command from the HVAC control module. 

This problem triggers temperature blowing hotter air than the setting or command. Use an advanced scan tool to identify a faulty blend door actuator. Try to notify if there is a clicking noise from the dash. It is a sign that there is something wrong with the internal parts.   

You may fix the simple problem that causes your car AC blowing hot air on the driver side. You should bring your car to a dealer or call a certified technician to diagnose the problem. Let them repair the AC to prevent other internal parts issues.

The Causes of Car AC Blowing Hot Air All of a Sudden, How to Repair, and Prevent It to Happen Twice


The Causes of Car AC Blowing Hot Air All of a Sudden, How to Repair, and Prevent It to Happen Twice

Have you ever experienced your car AC blowing hot air all of a sudden? It makes you confused, doesn’t it? Car AC blowing hot air (why does car ac blow hot air) is one of the most common problems. The most important thing is that you know the causes, how to repair it, and the way to prevent it from happening again. The information below will help you.

The Cause of Car Blowing Hot Air All of a Sudden

There are some causes you should consider related to car AC that produces hot air. First, it can be because the air filter gets clogged. The function of the air filter is to remove solid impurities from the air. Clogging issues interrupt the airflow since dust and contaminants stick in the system. It makes the air circulate and pass through the AC system in high temperatures.

car ac blowing hot air all of a sudden

Second, a problem in the condenser can also cause car AC blowing hot air all of a sudden. This component cools and condenses the refrigerant vapor into a liquid form. It also composes other components, such as a motor, fans, condenser coil, circuit board, and compressor.

Third, the malfunctioning thermostat is another issue dealing with car AC that produces hot air. The function of this component is to regulate temperature, prevent overheating, and cool.

The Way to Repair Car Blowing Hot Air All of a Sudden

In case the air filter gets clogged, you should check it and clean the dust or debris. Use an air pump at the lowest level to get rid of the dust. The problem can be coming from the condenser if you hear any strange noises from the condenser unit and the AC blows hot air.

Even if you don’t hear anything from the condenser unit, it still is a sign of a faulty condenser. Replace the old condenser unit with a new one to fix this problem.
Use a multimeter to check the amounts of volts of the AC. The amounts of volts indicate the performance and condition of the thermostat. Bring your car to the dealer to replace the thermostat.

The Way to Prevent Car AC Blowing Hot Air

Regular maintenance is the key to preventing a car AC from blowing hot air. For example, you can replace the filter every 3 months. Remember to recharge the car AC with refrigerant.

On the other hand, you shouldn’t turn the AC on if the refrigerant is insufficient. Ensure that you turn the AC on regularly at least once a week or two weeks. It keeps the compressor working properly.

Remain calm when a car AC blowing hot air all of a sudden, especially while driving the vehicle. Turn it off and find out the problem first. Call a professional technician to solve it. Then, maintain the AC to prevent the same problem twice.
