Car Air Conditioner Freon Leak

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.

Car air conditioner freon leak.

Your car or truck s air conditioning system operates on a tightly closed circuit of circulating freon. Cars and trucks can also use an expansion valve to meter refrigerant. Depending on how severe your freon leak is recharging it with one can of refrigerant may not last long. Your car s air conditioning system compresses refrigerant gases into a liquid then releases the gas through a radiator like evaporator coil.

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. The sudden expansion of the gas chills the evaporator coils. You want to position the sniffer in the very front of the compressor and at the lower part of the clutch. 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. Most car air conditioning systems have an orifice tube that is by its very definition a small hole that meters freon. The most common causes of broken air conditioning are leaks or compressor issues. The temperature at the dash vents should be in the 45 55 degree range.

Because of its unique properties a c refrigerant rarely leaves a visible trail streak or odor behind when it leaks which is why it s hard for the untrained eye to spot. Having your car s air conditioning go out suddenly can ruin your day fast. There shouldn t be even the tiniest leak in the system. An auto air conditioning leak is probably the most common problem found when your car ac system isn t blowing cold air.

Then the low pressure cut off switch disengages the compressor. 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.

If your car ac is leaking freon most likely your complaint is that the air is not blowing cold.

Some refrigerant is lost naturally over time. If your air is blowing cool but not cold the problem could be a clogged filter cooling fan problem radiator trouble or it could simply be that you need to recharge your ac. There are a number of potential causes for low refrigerant in your carâ s ac system. What can happen is the freon will leak out and reduce the total pressure in the system.
