Why is my car AC blowing out warm air?

25
Hot air coming from your car AC vents can mean that you have low levels of refrigerant. It can also be due to a problem in the condenser, the compressor, the cooling fan, or the electrical system of your car.


Hereof, why is my car air conditioner not blowing cold air?

The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

Subsequently, question is, does AutoZone do free AC checks? Some places charge you for testing your car, but at AutoZone, it's free. Don't buy a part you don't need. AutoZone will test your car's parts for free. We can test your car's battery*, alternator*, starter* and voltage regulator while they're still on your car.

Subsequently, question is, why is half my car AC blowing hot air?

The condenser in your air condition system looks a lot like a radiator and is mounted at the front of your vehicle. Like having a blocked condenser, having broken cooling fans can cause a lack of cooling at your condenser and could cause your car AC blowing hot air.

How much does it cost to fix your air conditioning in your car?

This generally includes replacing a few parts like hoses, sensors, or either the compressor or condenser. CostHelper readers report paying $171-$727 for minor air conditioning repairs, at an average cost of $488. Extensive auto air conditioning repairs can cost $1,000-$4,000 or more, depending on make and model.

Why is my air conditioner blowing hot air?

Most likely, if you're having issues with your air conditioner blowing hot or warm air, it's either a problem with the compressor/outside unit or your air conditioner is low on refrigerant. You may also have a return duct that is broken or disconnected and is pulling in unconditioned air from outside or an attic space.

Can low coolant affect AC?

In a properly operation system the engine coolant temperature should not affect the cooling of the air conditioner. But technically it is not the high coolant temperature causing the A/C problem. It is the lack of airflow across the condenser and radiator causing one problem in two systems.
