Two Common Central Air Conditioning Problems
The refrigerant in the system may be low from a possible leak. The leak should be located, repaired, and recharged.
Compressor failure is a problem, which usually requires replacement of the unit. Usually when a compressor is replaced, the entire condensing unit on the exterior is replaced. The typical life expectancy of a compressor in a central air conditioning system is 8 to15 years, depending on geographic location.
