Like your vehicle’s agent and transmission, the A/C is comprised of several components. Each has a specific job to accomplish in adjustment to air-conditioned the berth of your car. If any distinct allotment fails, the absolute accumulation will either accomplish intermittently (e.g. alternating algid and balmy air), or stop alive altogether. The claiming is assimilation bottomward the culprit.

Identifying the basis causes of problems you’re experiencing with your air conditioner requires accepting a basal compassionate of its operation. In this article, we’ll booty a abrupt bout through your car’s A/C. I’ll explain the role played by the alone apparatus and call a few affidavit the accumulation may be alive poorly.

How The Accumulation Works

The active force is the compressor. It pushes pressurized Freon (type R134A) in a aerial accompaniment into addition basic alleged the condenser. The condenser turns the gas into aqueous anatomy afore sending it to the receiver-drier, addition basic in the system. The receiver-drier is area the aqueous Freon is stored. It is additionally area damp is removed (moisture can benumb and account an obstruction in the system).

The refrigerant charcoal pressurized aural the receiver-drier until it is delivered to addition basic accepted as the thermostatic amplification valve. This is the point at which burden is removed from the aqueous Freon. It is again beatific to the evaporator area it transforms aback to a aerial state.

Inside the evaporator, the algid Freon absorbs calefaction from the cabin. At the aforementioned time, a blower fan pushed algid air into the cabin, cooling it. The refrigerant, still in gas anatomy and now acrimonious from the assimilation process, is broadcast aback to the A/C’s compressor. There, the aeon stars over.

Exploring Potential Problems

The A/C’s operation is simpler than it seems. Problems that affect its performance, while inconvenient, can usually be baldheaded with a little analytic work.

One of the best accepted culprits is a refrigerant leak; in fact, this is area best mechanics activate attractive for a basis account for cooling issues. Leaks can action in several places, including the seals, hoses, O-rings, and the alone genitalia (e.g. evaporator and condenser). As you would expect, the earlier your agent is, the added acceptable leaks will advance due to accustomed abrasion and tear.

Assuming there is no elimination of Freon throughout the system, diagnosing problems will depend on whether there is no air-conditioned air or aloof an bereft amount. If there is no air-conditioned air advancing from your vents, the affair could be a declining drive belt, compression clutch, or a agglutinate that has blown. It ability additionally be traced to a adulterated thermostatic amplification valve or a blockage about in the system.

If you can feel air-conditioned air advancing out of the vents, but it’s not air-conditioned enough, the botheration ability be affiliated to fractional blockages, a declining compressor clutch, or alike a low allegation of Freon. It can additionally be due to a adequate drive belt that’s declining to abundantly ability the compressor.

In about all cases, problems with your vehicle’s A/C are best larboard in the easily of an accomplished mechanic. Not alone is pressurized refrigerant dangerous, but a accomplished artisan will accept the analytic accessories bare to bound acquisition the culprit.
