Default Re: A/C not producing sufficient cold air

The compressor cycles on and off. Some cold air is produced but not an adequate amount to make it really cold. I can run the air set a 60 deg and the fan on high constantly and the interior barley cools off.

If the compressor cycles, the system is low on freon. A properly charged system runs the compressor continuously.
