With the price of a/c today it would be better to replace it then repair it. there could be a leak in the system or a bad compressor.

Hi,
If ur AC is not coolling properly thn u must go for replacing a fuse, resetting a circuit breaker or checking to see if the thermostat is set properly. If an electrical problem isn't the cause, the refrigerant may be low if the system still runs but does not cool properly. This can be corrected by having an EPA certified technician add necessary refrigerant. Most likely, if the problem involves any major part, such as the compressor, you would hear strange noises similar to those of any mechanical equipment not running correctly, or the unit might not run at all.
Go for replacing both theoutdoor condensing unit (which includes the compressor) and the indoor coil on my central air conditioning system at the same time
Matching a new condensing unit with a new coil is the only reliable way to be certain you are going to get the rated efficiency of the new equipment. Matching a new, high SEER (seasonal energy efficiency ratio) condensing unit with an old indoor coil probably would not result in optimum efficiency.
Goodluck,
Dont forget to rate me as fixya..

This is the service manual for this system. It might give you an idea on what the problem could be. Page 27 should be your area to start. There are two for the PTAC series. I'm not sure which one will pertain to you.
