We use heat pumps in the midwest where its plenty cold, mine is a 3 ton,16
seer and heats a 1600sq ft ranch main level and 700 down stairs, holds 69
degs, when the outside temp is 17degs.

I am in the process of building a 3000 SQFT house that my builder spec'ed
for two zone heat. He called my yesterday and said after he met with his
mechanicals subcontractor that two zones were probably not enough since the
room over the mudroom and the room over garage were (I guess) to far away
from the furnace to be efficiently heated. He was suggesting we add a heat
pump for those two rooms (with AC of course). We live in Northeast and I am
worried this would be terribly expensive solution. I questioned him about
adding a third zone and he said he'd get back to me after talking to the
sub again. Does a heat pump make sense? I don't understand why a third
zone couldn't be added fairly easily. Is this a cost issue? Wouldn't a
larger BTU furnace do the job? Our contract specified two zone heat, is
this something I should have to pay extra for or would this be his cost.
Thanks in adavance for any advice you have.
