Why is My Car’s AC Blowing Hot Air?
Updated: Apr 28, 2021
Staying cool is absolutely vital in the summer. And if your car’s AC system is blowing hot air, then it certainly isn’t helping you cool off. So, what’s the problem? If your AC is not actually blowing cool air, then there are a few different issues which could be in play.
Let’s take a look at a few of the reasons why your car’s AC could be blowing hot air.
The Refrigerant is Leaking
One of the most common roots of this issue is a lack of refrigerant within your car’s AC system. Within your car, the AC system is sealed and thus, you should never need to top off your refrigerant.
However, if the air coming out of your system is hot, then it could not be getting the refrigerant it needs. This refrigerant can leak out of various parts of your AC system, and fixing this issue can prove to be quite complex. The goal will be to fix any leaks and the recharge your system. Something we strongly recommend letting your Maryland mechanic work through.
Your Compressor is Worn Out
Your car’s air compressor is the heart of the A/C system. The way it works is by taking the refrigerant and pressurizing it, then it changes the internal cabin temperature according to the levels you adjust on your A/C console. Like many engine parts, the compressor is powered by the serpentine belt. If your compressor is worn out, then it can’t generate your cold air, and thus, the fans will only blow hot air.
If you hear strange noises coming from your A/C system along with hot air and/or fluid leaks, then you probably have a compressor problem.
Your Cabin Air Filter Needs Replacement
In the event your A/C is blowing cool, but not cold, air then the problem could be with your cabin air filter. A dirty filter can cause your A/C to work less efficiently. Essentially choking the system by letting less air through than is required.
