Needless to say, A/C systems have definitely made traveling in cars easier and more comfortable.  When spring and summer temperatures start to boil along the highways and congested roads, there is nothing more refreshing than the cool blast of air conditioning from the vents of a car, truck or van.

How does the air compressor cool your air?

The minute you press the A/C button, you have full control of the air compressor. The A/C compressor clutch activates the mechanism to compress and hike the temperature of the refrigerant. After activation, the refrigerant is then sent through the condenser, where the heat is lost. Next, the refrigerant goes through the dryer and is purified of contaminants. The refrigerant is then stripped of its pressure after it passes through the expansion valve. The final step is traveling through the evaporator inside the dashboard, and the refrigerant is rendered super cold and moisture free.

What is the longevity of A/C air compressors?

Certain factors that might indicate the likely lifespan of an A/C air compressor is the vehicle’s age. For instance, while new vehicles are equipped with more durable compressors, the toll of mileage can affect any of the internal parts. If the compressor is bearing repeated undue stress over time, it could slowly lose its ability to direct cool air into the passenger compartment.

The compressor could benefit from the relative lack of wear during colder months, but it can also stagnate if left to hibernate. That is why, it is recommended to activate the A/C for at least 10 minutes every 30 days, during the winter months, to ensure it doesn’t get permanent rest. In some cars, the compressor is also utilized to offer heat and ventilation, both of which tend to be used primarily between late fall and early spring. If you have already had the A/C air compressor replaced, its life expectancy may be shorter than the original unit that came with the vehicle as it rolled off the assembly line.

What is the maintenance schedule of an A/C air compressor?

If the cold air is either slight or nonexistent in the air coming through the vents, it is likely due to problems with the system. Depending on the extent of the problem, you either need to get a part repaired (such as the A/C compressor clutch) or get the A/C air compressor fully replaced.

In any case, when your vehicle’s A/C starts to lag, it is time for an inspection, so you can figure out what is wrong and address the issue immediately.
