I am about to start an 3 ton central AC in my 1500sq ft Ranch, I have all the wiring run and poured the pad, I am going to get a Payne unit question I have is the HVAC tech who is going to braze the lines and set up the system after I am done, gave me a choice between a PH15NB036ooG which is a 15 SEER Heat pump & cooling or a PA16NA036oog which is a 16SEER cooling only, the heat pump model is actually $135 less money, and the air handler would be a PF4MNA037. in the long run are there any more expensive parts in the Heap pump unit, is this a factor to be thinking about. which would be the wiser choice,
thanks Chet
