I recently had a goodman 3.5 ton 13 seer condenser and air handler installed in my home. I can only get a 14 degree difference, which is worse then my old unit. it turns out that the air handler is a 14 seer, would the difference in seer make a difference in the performance of the entire unit?
I would check fan speed. it's probably on high. you might be moving more air with new system. a dirty evaporater on old unit woud have gave you a larger temperture drop.

you have a missmatched system, for it to work try removing the orfice on the high side txv it is not allowing the evaperator coil to fill with refrigerant properly coleman and intertherm dont like each other since they control a large market in the manufactured housing heating and cooling units electricaly connecting the componets together no issue prefromance sometimes is the issue hope this helps

I assume r-22 refrigerant by the pressure... you have a saturate temperature of approximately 41 degree and 71 degrees at the service port this equates to a 30 degree superheat. a condenser saturation temperature of 105 degrees and since the liquid line temp at the service valve is not given only the enterin indoor coil on the liquid line a 96 degree temperature this would equate to a subcooling temperatureof about nine degrees. You have too high of a superheat reading. verify that the bulb for the txv is correctly positioned and insulated. if it is then you need to remove the bulb from the suction line, hold it in your hand to warm it up and see if the superheat changes. you could also have issues with your ductwork. If the supply temperture is around 50-55 degrees then the unit is doing all it can.. Check the txv and the ductwork as the subcooling indicates that the condenser side is doing it's job, but the superheat readings indicate that you are starving the evaporator..

Hi, 2,500 ton unit would be the size of a 15,000sq.foot warehouse! I think you mean a 2 1/2 ton Rheem condenser. You could run an add under Craigs list.com, and if the unit is in good shape, I would ask no more then $600 for it. As a Contractor, I can get them anytime new for around $660.00. If you can get $500 for it jump on it. Best of luck to you,
