A faulty air conditioning system can make driving unbearable in the hot summer months. A minor inconvenience for the rest of the year, a broken air conditioner will certainly be an emergency when the mercury rises. Here are the most likely reasons your device is rubbing together.

Refrigerant Leak:

Refrigerants are substances that are responsible for cooling the air that comes out of your vents. When properly pressurized in a closed system, the refrigerant diffuses into a gas which is then employed to cool the interior. However, if this closed system leaks, the refrigerant level may drop and affect operation. In other words, the fan is just blowing hot. A common problem with auto air conditioning repair in old cars is the challenge where it leaks. As a result, it is often necessary to examine the entire device in order to properly diagnose and fix the problem.

Bad Compressor:

Another common problem with car air conditioning repair in old vehicles is worn compressors. At the heart of the device, the compressor is responsible for circulating the refrigerant throughout the system. If it is damaged, the ventilation openings will only blow warm. Although age, dirt, or other damaged components are the most common cause of compressor failure. If it cannot be repaired, the compressor will need to be replaced.

Air Filter Clogged:

The passenger air filter is installed in the outside inlet of your car's ventilation system and removes dirt, dust, and grime from the outside environment before being pumped inside. If this filter becomes clogged with collected waste, airflow can be obstructed. Simply removing and cleaning these components is often enough to make things blow again.
