Our condenser on our 11 yr. old AC is dead. No one has been able to solve 2nd story cooling problems. We have been told by two other contracters that the ductwork is undersized and that there is a lack of sufficient return air. Current thoughts are to increase both the supply and demands ductwork sizes at the furnace, as well as adding another return in the basement.
Contracter sells Lennox and Comfortmaker, but apparently can't get a Lennox right now. We are to choose either a 3 ton 13 SEER and a 4 ton 14 SEER as well as the appropriate coil changeover. Any thoughts?
