I am shopping for a new heat pump. My house is 2-story (finished basement), faces NW in back & SE in front, 2063 s.f. outside measurement, 14 windows, in Knoxville TN. I use the a/c only when the heat gets too high w/thermostat at 79; winter thermostat is 57 - which has to stay on.
I have an estimate for a 3-ton Amana ASZ14, which has a 2-stage compressor. Since I don't use much a/c, do I really need a 2-stage compressor? Wouldn't the Amana SSZ14 be more than sufficient?
It's absolutely necessary, monetarily, that I keep electrical use to a minimum. I have done the energy star Home Energy Yardstick, which resulted in a 9 - probably because I don't use much a/c & keep heat so low. But, 57 is too low for a senior!
Thanks for any help. Of course, if someone thinks this unit is not really good, please advise. I am running a 15-year old Janitrol 3.5 ton, which runs great. I am aware that Goodman makes both Janitrol and Amana.
