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. car air conditioning recharge

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.
