I'm a homeowner in southwestern Pennsylvania looking to replace a Goodman 2.5 Ton 10 SEER heat pump from 1992. I got a load calc from a dealer who used the Elite Software load calculator that recommends 3.06 tons for a 98%/2% split.
We only have electric service so this is paired with an electric furnace.
I'm leaning towards a Carrier Performance series with the Edge Thermostat but I'm looking for advice on valid matching equipment.
Proposal 1 for a 3 Ton 15.5 SEER 9 HSPF system:
Heat Pump: 25HPA536H005
Air Handler: FV4BNF005
Electric Heater: KFCEH3201F20
Proposal 2 for a 3 Ton 15 SEER 8.6 HSPF system:
Heat Pump: 25HPA536A003
Air Handler: FV4ABNF003000
Electric Heater: KFCEH3101C15
I've been trying to piece together information and it looks like the equipment in Proposal 1 is better, but I'm questioning the compatibility of the 3 Ton Heat Pump and the 5 Ton air handler. Is this okay? What are the possible side effects? It seems to make sense to get the FV4 as the variable speed fan to help the electric costs, I just want to get the right one.
