Though bearable in the colder seasons, It's never a pleasant ordeal having a car AC that blows hot air during the heat. So, if you've ever wondered what could be causing your car AC to blow hot air, read on!
There are four main reasons why your car AC could be blowing hot air, these include:
- A Malfunctioning condenser
- A non-functioning compressor
- Leaking refrigerant
- A malfunctioning electrical system
The AC condenser is responsible for cooling down the AC refrigerant. This ensures that the refrigerant is able to absorb the heat as well the humidity that is pulled by the AC. If the condenser fails to fulfill its purpose, the AC fails to function properly, thus blowing out hot air.
The compressor is the main part of the AC and its purpose is to circulate the refrigerant through the entire AC system. If the compressor fails to do this as intended, the antifreeze fails to reach the condenser and thus it remains hot. You tend to notice that the compressor breakdowns after prolonged periods of not using your AC.
This is the most common cause of a broken car AC that blows hot air. The refrigerant is a liquid in your car AC which keeps it cool. It does so by expanding and contracting as it eliminates heat from the AC cabin. If your refrigerant is leaking then the car AC will fail to function properly.
Malfunctioning electrical system
If your car AC blowing out hot air is not the result of any of the above-mentioned then it could be because of this last possible cause, a malfunctioning electrical system. This could be anything from a blown out fuse to some frayed electrical wires within the AC.
How to maintain your car AC
There are some other ways to have your car AC blow cool air all summer. These include:
- Flushing your radiator
- Topping off your coolant
- Turning on your car AC more often
- Checking your fan belt or having it checked
