I am looking for insight into a new system for a 2550 sf house in central PA. The houes is 2 stories, with separate duct systems on each floor. First floor has low supplies and high returns in each room. Second floor has ceiling supplies and a central return also in the ceiling. Heat is currently electric baseboard, with 2 AC units installed in 1990.
I'm wondering weather installing 2 heat pumps would be the best way to go, as having a gas line installed would be 2-3k additional, and all other appliances are new, and electric.
I am considering Trane XR1r of XLi14 units, probably 2 ton on 1st floor, either 2 ton or 1.5 on 2nd (waiting for loand calc).
My questions are:
1. Do heat pumps provide sufficient comfort in this climate (lows often into the teens in January and February, even lower on rare occasions)?
2. Would heat pumps be an economical choice?
3. Are there better options than the Trane units I mention, given that heating is the primary concern here.
4. Would a 1st floor gas furace and 2nd floor heat pump be a better option, even after factoring in the cost of the gas line?
