We are used to having Air Conditioning (AC) professionals and even utility companies telling us that the AC systems on our houses need to be checked every year. This is important to maintain system efficiency and lower operating costs. Your car’s AC operates in a harsher environment then the AC on your house. The refrigerant system under the hood can see temperatures approaching 200 degrees. There is also vibration that the system endures when you car drives down the road from the engine and road surface. So it is important that you take care of your AC system so it can take care of you when it is so hot outside.
So how often should the AC on our cars be inspected?
The performance of the AC system on your car should be inspected once every year. Many of today’s modern automobile AC systems hold between 14 to 30 ounces or more of refrigerant (commonly referred to as Freon). Because of the harsh environment the system operates under, refrigerant loss can and does occur. This occurs unknowingly to the driver as AC vent temps can actually become cooler as the refrigerant level drops slightly from specification. But, when refrigerant levels drop, the AC compressor can become starved of lubrication and can overheat. This can cause a failure of the compressor which can result in a repair bill of up to $1000 to $2000 to get the AC system operational again. So have your AC system checked annually to prevent an unneeded expense.
