/estimatorHVAC savings calculator]
I am looking for some sort of HVAC savings estimator or calculator.
Currently a 1999 home approx 2650 sq feet in ga. 2- 2 ton units I believe are around 13 seer, furnace is running I think about 80% efficient.
Want to change a downstairs unit to a Trane 16i heat pump with an xv80 furnace. I have come across
but am not having any luck with it since it doesnt want to give me good numbers from a furnace to a heat pump.
