3 Common Auto Air Conditioning Problems, Meriden, Connecticut

As temperatures go up during the summer, car owners need their auto air conditioning systems more than ever to drive comfortably. And when the system starts blowing warm air, or it fails to maintain a cool cabin temperature, you need to have it inspected for possible issues. Below are some of the reasons why the auto air conditioning unit stop working properly.

3 Causes of Auto Air Conditioning Issues

1. Refrigerant Leak

The refrigerant is a liquid that travels from one part of the system to another during a cooling cycle. Although AC units are tightly sealed, loose connections and damaged seals may result in leaks. Its symptoms are not similar to an oil or coolant leak, since the refrigerant evaporates into gas once it escapes. Instead, it leaves an oily residue around some of the AC components. Auto repair technicians add special dyes and use electronic detectors to discover leaks throughout the system. If left undiagnosed, this issue can lead to moisture damage.

2. Electrical System Issues

The auto air auto air conditioningconditioning system is equipped with numerous fuses, switches, and relays. If intermittent cooling occurs, it might be caused by an electrical problem. Faulty switches and relays, such as the compressor clutch and AC control switch, may result in a lack of power or a voltage that is too low to run the cooling system for prolonged periods. This issue can also sometimes be attributed to a broken temperature sensor or problem with the control module, so you need to have it diagnosed professionally.

3. Compressor Failure

Because the compressor is responsible for circulating the refrigerant throughout the system, its breakdown results in a noticeable lack of cold air in the vehicle. Compressor failure leads to the production of sharp metallic debris that blocks the passageways, causing weakened airflow. Another reason for a damaged compressor is contamination from moisture due to leaks, which produces black sludge and results in a blockage.
