Getting Toasty? Top 4 Reasons Your Car’s AC Blows Hot Air

As the summer turns up the heat in Canton, CT, is your car’s air conditioning system ready to save the day? 

If you haven’t already gone on a trial run, now is the time to do it, especially if you’ve kept the AC off more often. As you do that, brace yourself for the possibility of your auto air conditioner blowing hot air instead of a refreshing icy cool breeze.

Luck not on your side? That’s okay. We’re here to help. At Collinsville Auto Repair, we specialize in diagnosing and repairing car air conditioning systems of all kinds. 

Our AC repair services often start with customers stating that their car AC blows hot air. We get our diagnostic tools at the ready, often tracking down the four following causes of a failed car AC system.

1. Refrigerant Leak

The refilling takes place in an auto repair shop.When operating correctly, your car AC constantly cycles the refrigerant through the closed loop. The system can produce all the icy cold air you expect and deliver it on demand through the vents.

However, all the refrigerant flows into the atmosphere if a leak occurs, leaving your system empty and non-functional. Simply recharging the system won’t help either. Pinpointing and repairing the leak is key in restoring the function of your auto air conditioner.

2. Condenser Blockage

The condenser has the important job of turning refrigerant from a gas into a liquid, readying it for another trip through the system. This vital component sits right up front near the radiator in most vehicles.

The upfront position helps the condenser cool down the refrigerant fast, but it also puts it right in the line of fire. Road debris often flies up and hits it, resulting in a puncture and damaging its cooling properties. When that happens, replacement is the only way to repair your AC.

3. Compressor Catastrophe

The compressor actively circulates the refrigerant through the system, so it can absorb heat and produce cool air. The refrigerant turns from a liquid to a gas, leading up to the condenser turning it back into a liquid again.

The cycle continues—just as long as your compressor keeps working right. If the compressor fails, then the refrigerant remains dead in the lines. At that point, you must have it replaced to get cold air flowing out of the vents.

4. Electrical Gremlins

Modern cars rely on electronics to know when and how to operate all the interconnected systems, including your auto air conditioner. So, when electrical gremlins rear their ugly heads, your AC could go on the fritz—and fast.

Everything from blown fuses to failed control modules has the potential to leave you in a (not-so) cold sweat. Fixing the problem isn’t a blast either, but our talented auto techs in Canton, CT make it look as easy as pie.
