Heat pump vs furnace and A/C
Hi, looking at and comparing costs of Heat Pump vs conventional A/C+Gas Furnace. I have read that heat pumps are more expensive but I don’t understand how/why.
For a baseline/comparison purposes, I looked up a 3 ton Carrier Infinity 18SEER/11HSPF Variable Speed Heat Pump unit that prices about $3600 for hardware/ $10K installed (just internet searches). Not sure if these cost numbers are realistic.
Here are my questions
(1) how would this compare to the hardware/install cost of a comparable 3 ton (say 15 or 16 SEER) A/C unit plus gas furnace (variable speed). I know there are variables/factors (like furnace size) left out, just want a ballpark estimate. I’m trying to understand why a single unit (Heat Pump) would cost more to install than two units, running on two fuels (A/C and gas furnace).
(2) Are their any resources/calculators that would help me estimate operating costs based on Zone, HDD/CDD, electricity cost, gas cost/therm etc…? I understand Heat Pumps are more energy efficient, but not necessarily more cost efficient to operate, depending on electricity and gas costs.
thanks in advance!
