Why is the AC in my Car not Working?


If you have lived in Texas for any time at all, you know that having a working air conditioning in your car is vital to make it through the summer. Driving around on a hot summer day in Texas without properly functioning AC in your vehicle is not only uncomfortable but unbearable.

If you have noticed that your AC doesn’t seem to be doing its job, you are going to want to try to diagnose the problem as soon as possible. Whether the fan isn’t blowing properly, or the air is taking way too long to get cooler, or the air never appears to get cold, there are multiple factors that could lead you to think “something just isn’t right.” Some of the most common issues that appear with your air conditioning may be:

#1 Your Freon may be leaking

Leaks are typically the most common reason for improper AC functioning. Freon is the chemical in your car that keeps the air cool when working through your air conditioning. If there is a leak where the Freon is stored it could be running low or have run out completely. If you try and fix this problem by simply adding more Freon, your solution is likely going to be very temporary. If there is a leak you will need to have your car taken in to have the area fixed to retain the proper amount of Freon.

#2 Your AC needs to be recharged

Another common issue is that the refrigerant needs to be recharged. It is possible for you to do this yourself, however many people prefer this done by a trusted professional. Here at Nortex Lube & Tune, we will happily help you solve this and any other mechanical issues you may be dealing with.

#3 The AC compressor isn’t communicating with the car’s computer

As cars today are computer controlled, there are a lot of complicated parts involved. Sometimes it is difficult to diagnose what exactly causes this miscommunication with the compressor and the AC. It is likely that there is a malfunctioning part, and this will need to be replaced by a qualified mechanic.

#4 The air door is stuck

Inside your car, there is a ventilation system. Inside the ventilation system, there is a tiny hatch. This hatch is called the “blend air door.” Its function is to change the air coming into the car from hot to cold, if it is stuck or not functioning properly, it will not change the air temperature and this is another one of the AC repairs in McKinney that you will need to be addressed by a professional.

#5 Your AC’s fan isn’t working

If you can somewhat feel that there is cold air, but it isn’t blowing out of the vents, this is likely a problem with your AC’s fan. This fix can be simple or may require replacing the fan unit. Unfortunately, this is another issue that will likely need to be addressed by a professional as it can be a quite a complicated feat.

It is possible to fix some mechanical issues yourself, but generally, your best option is to have it done by a professional at a trusted McKinney car shop.
