Car AC Not Blowing Cold Air?

If it’s mid-summer and you are asking “why is my car not blowing cold air”, chances are you’re having a bad day. July 2019 was the hottest month ever recorded on the planet and with no signs of slowing down. Having your car or truck ac system not working functioning can not only be uncomfortable, but it can also be downright dangerous. So many times, when folks call us wondering “why my car ac is not blowing cold air?”, they have been dealing with the issue for a long time. Typically, they put off their ac repair until they can no longer stand it. Part of the problem is not understanding why the ac is not working. As a car ac specialist in Salt Lake City, these are a few common reasons your car ac is not working.

Common Reasons Your Car AC is Not Blowing Cold Air

You Are Low on Freon

This is the most common reason your car or truck ac is not working. Freon is a type of refrigerant. Refrigerants are fluids that run the air conditioning systems. Like gasoline in your engine, your car ac needs freon to function. When you are low on freon, your air conditioning will not be able to provide cold or even cool air. If this is the case, chances are there is a leak in the AC System. There are a few ways to know if you have a leak. Sometimes you can hear an audible click when the air conditioning turns on. You may even hear hissing sounds when the engine is not running. If you are experiencing these symptoms, it’s time for a truck ac repair. Only experienced repair shops offering air conditioning services can properly diagnose this issue with the use of fluorescent dye and ultraviolet leak detection lamps.

AC Fan Motor Failure

Another common reason your air conditioner is not properly working is AC fan motor failure.  This can be more easily diagnosed on your own than other issues. You can tell this is the problem when you can feel there is cold air, but the car is just not blowing the cold air. Most cars will have one or two fans for distributing the cold air from the AC system to the cabin. In some cases, it will be a wiring issue however in more serious instances, a new unit will need to be installed. Diagnosing is easier than fixing as the repair may require taking the car dashboard apart so unless you know what you are doing, it is best to visit a shop.

Restrictions or Blocks in the System

The air conditioning system is complex with various parts, wires, components, and hoses. The contaminant you need to be concerned with your AC system is moisture. If you have tried an at-home freon recharging kit and your air conditioning is still not working, moisture in the system could be the problem. When there is a restriction or block to any part, the entire system is vulnerable and may not function properly. This is one of the main arguments to take your vehicle to a certified shop from the beginning for a proper diagnosis.
