2. Check the compressor

Another common cause of a hot AC system is a faulty compressor. If your car’s air conditioner isn’t blowing cold air, the compressor is likely at fault, and you’ll need to get it repaired or replaced as soon as possible.

There are a few reasons why the compressor might not be working, including a loss of refrigerant, an electrical problem, or a problem with the drive belt.

3. The evaporator isn’t working

Another possible cause of a hot air conditioner is an issue with the evaporator. If this component works correctly, it can remove excess heat from the air circulated into your car.

To diagnose issues with the evaporator, you may need to enlist the help of a trusted mechanic or auto repair technician. They can run diagnostic tests and make the necessary repairs to get your AC blowing cold again.

4. Check the condenser

One of the reasons for your faulty air conditioner might be a condenser issue. It is often due to clogged condenser fins or a faulty cooling fan that isn’t blowing air into the system as it should be.

If you suspect an issue with your car’s condenser, use a soft-bristle brush or a vacuum hose to clean the condenser fins. If you continue to experience hot air, it may be time to have your car’s AC system inspected by a professional mechanic.

5. The blower motor is not working

If your AC is blowing hot air, it’s also possible that the blower motor isn’t working correctly. It can be due to issues with the engine or a faulty resistor.

If you suspect this might cause your hot air problem, you should have your car inspected as soon as possible by a mechanic or auto repair technician. 

They can diagnose and repair the blower motor, getting your AC blowing cold air again in no time!

6. Check if the AC system is leaking

It’s also important to check if your car leaks into the AC system. Faulty fittings, loose hoses, or damaged condenser coils can cause this. The leaking can cause your AC to blow hot air, and it’s best to address these issues as soon as possible.

To check for leaks, look under the car around the fittings and hoses connected to the condenser. If you notice any signs of a leak or other damage, get it repaired immediately. 

Otherwise, you could have worse air quality in your car and more costly repairs down the road.

Pay attention to your system

As part of your vehicle, keeping your AC running properly is essential to get the most out of your car.
