Heat Pump Payback in Prescott, AZ
Will a heat pump pay off in Prescott, AZ?
Prescott sits right on the fence, how long you'll own the house decides this one. $5,500 is what Prescott would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $369 saved annually, for a payback of roughly 14.9 years. Whether that's worth it in Prescott depends on how many years you expect to own the place.

The climate behind Prescott's payback figure
3997 heating degree days pile up here every year, so Prescott has a real but manageable winter; the cooling side runs to 1590 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 15.1°F here (coldest 2024 reading 12°F), which works out to a seasonal COP of 3.06 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Prescott, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Ernest A. Love Field Airport, the closest NOAA station, 4.4 miles out.
Prescott's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,307 heating kilowatt-hours annually on top of cooling, totalling about $725 a year on electricity. The gas furnace it replaces burns roughly 42 Mcf a year at $18.58 per Mcf here, for a running cost near $1,094 a year including the old AC (electricity here runs 15.55¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $31 ahead.
How sensitive Prescott's result is to prices
This result holds unless electricity climbs above 29.7¢/kWh (it is 15.55¢ now) or gas drops below $9.72 per Mcf (now $18.58); past either point, gas becomes the cheaper fuel in Prescott. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $369 a year saved, a difference under $2,583 pays back within 7 years here, and under $3,690 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Prescott heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,169 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 8.6 years.
