I believe you are referring to the supply air should be 18-21F cooler than the return air.

As others have said, the following things can cause poor performance:

Incorrect air flow (dirty filter, dirty evap coil, wrong fan speed)
Incorrect Refrigerant charge
Dirty condenser coil
Poorly insulated house
Poorly sealed windows, doors, etc.
Poor installation


One of the companies mentioned in this thread has done work for me in the past. Let’s just say, they are the reason I took the EPA test and have learned to do my own work.
