Three Reasons why Your A/C is
Blowing Warm Air

When it is working properly, your cars' air conditioner is a wonderful thing. When it is not, which of course occurs on the most brutally hot day of the year, the A/C suddenly becomes a cruel joke, blowing warm, stale air into your vehicle. If your air conditioner is blowing warm air, or just not working properly, it is best to schedule a service ASAP to maximize your comfort.

Automotive A/C systems have certain intricacies in their design that render them difficult to repair without the proper equipment and knowledge base. On top of that, there are certain environmental concerns involved with refrigerant that require special attention. We've identified three common A/C System issues to help supply you with information on what may be going on with your vehicle

Three Signs your A/C is Malfunctioning

 

1. Refrigerant Leak

A refrigerant leak is unique in the sense that refrigerant evaporates instantly into a gas once it isn't under the pressure of your closed loop A/C system. A/C systems are sealed and therefore don't require refrigerant top-off's. If the refrigerant level is low then there is a leak that needs to be addressed.

Leaks in your A/C don't result in the normal tell tale puddles of fluid under your vehicle like those of an oil or antifreeze leak. Our certified technicians are trained to search for much less sinister signs of leaks like the oily residue which might be found on or around A/C hose units or connections. A refrigerant leak can also occur in the  

2. Worn out compressor

The compressor is the heart of your vehicle's air conditioning system. Its function is to circulate refrigerant through a series of Onlines that allow it to remove heat from your vehicles cabin. Similar to many other car parts, the compressor can wear out over time. Due to its complicated design, compressor failure can be attributed to contamination or other failed parts within the system.

There are some things that you can do to help prolong the life of your vehicle's compressor. First, make sure to run the compressor for about 10 minutes once a month in the off season, regardless of the temperature outside. This is easy to in most modern vehicles since they utilize the compressor when the defroster, which is used year round, is activated. Another way is to stop in to Pep Boys for a FREE A/C Quick Check (not available in the state of California) and an associate can give a visual inspection of the compressor to ensure that everything looks in order.
 

3. Problems with the electrical system

The A/C system in your car has a maze of wires complete with fuses, relays and pressure switches that work in unison to provide safe operation under normal operating conditions. If one of these electrical components fail due to age or defect, the system is designed to shut itself down to prevent damage to itself or unsafe conditions for the operator. Without the proper test equipment and, perhaps more importantly, the experience level of the individual diagnosing the problem, these issues are difficult to isolate.
