heat pump/gas furnace or AC/gas furnace
Indianapolis, IN. 2200 s.f. tri-level home. Replacing a 10 yr old 3 ton AC unit (SEER 10)and a 40 yr old gas furnace. So in this area do heat pump/gas furnace combos make sense? Some installers are saying yes, others say no, that indiana weather changes too much and heat pumps need 32 F to make more sense than using A/C.
