Car Air Conditioner Freon Leak

The most common causes of broken air conditioning are leaks or compressor issues.

Car air conditioner freon leak.

An auto air conditioning leak is probably the most common problem found when your car ac system isn t blowing cold air. Most car air conditioning systems have an orifice tube that is by its very definition a small hole that meters freon. If you load it up with stop leak and don t run it long enough you can plug this hole and the air will never get cold until you replace the clogged component. The front of the compressor is where the main shaft seal is located and a very popular place for freon to leak.

Your car or truck s air conditioning system operates on a tightly closed circuit of circulating freon. If your car ac is leaking freon most likely your complaint is that the air is not blowing cold. Your car s air conditioning system compresses refrigerant gases into a liquid then releases the gas through a radiator like evaporator coil. There shouldn t be even the tiniest leak in the system.

Then the low pressure cut off switch disengages the compressor. Car ac leaking freon. You want to position the sniffer in the very front of the compressor and at the lower part of the clutch. Cars and trucks can also use an expansion valve to meter refrigerant.

With the amount of pressure the ac compressor produces it doesn t take much for a tiny leak in the plumbing or hardware to render your system useless and leave you sweating to the oldies on the way to work. It takes years though so if your car isnâ t that old or the system has been recharged recently and is now blowing warm air again chances are good that youâ ve got a leak somewhere. Unlike motor oil and brake fluid car a c refrigerant is a colorless and relatively odorless substance that cycles through gas and liquid states. There are a number of potential causes for low refrigerant in your carâ s ac system.

This draws heat from air passing over the coils and out through the air conditioner vents inside the car cooling the interior of the vehicle. Again try not to get dirt into the nose of the sniffer. What can happen is the freon will leak out and reduce the total pressure in the system. The sudden expansion of the gas chills the evaporator coils.

Some refrigerant is lost naturally over time. Having your car s air conditioning go out suddenly can ruin your day fast. The temperature at the dash vents should be in the 45 55 degree range.
