3 Reasons your vehicles air conditioning might not be working


When it comes to air conditioning problems you can pretty much narrow it down to these 3 reasons.

1. Refrigerant Leak

Today’s air conditioning (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. When the leak is not obvious our technicians insert a florescent dye into the system. Once this is done the dye will show up after a day or so when the technician shines a black light over it. Leaks can be found on or around a/c hoses or connections. A refrigerant leak can also occur in the compressor, condenser, and or evaporator.-(essentially all of the components of your air conditioning system.)

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 stages 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 is activated.

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. These 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, the experience level of the individual diagnosing the problem, these issues are difficult to isolate.
