Heat Pump Payback in Jerome, ID
Should Jerome switch to a heat pump?
Here in Jerome, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. The heat pump would cost about $132 more a year to run than the furnace it replaces, a premium with no payback. There's no spin on that: Jerome's numbers say wait.

Why Jerome's climate drives this number
6024 heating degree days pile up here every year, so Jerome has a cold winter that leans hard on heating equipment; the cooling side runs to 844 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 8.1°F, and the coldest daily reading in the 2024 station record was -2°F. That puts the seasonal coefficient of performance at 2.89 for the recommended cold-climate unit. A cold-climate unit is the right call in Jerome, 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 Jerome County Airport, the closest NOAA station, 3.1 miles out.
Jerome's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,278 heating kilowatt-hours annually on top of cooling, totalling about $751 a year on electricity. The gas furnace it replaces burns roughly 63 Mcf a year at $7.69 per Mcf here, for a running cost near $619 a year including the old AC (electricity here runs 12.52¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $7,473 behind.
How sensitive Jerome's result is to prices
The heat pump would become the cheaper option in Jerome if electricity fell to 9.8¢/kWh (from 12.52¢) or gas rose above $9.79 per Mcf (from $7.69). At today's prices a cheaper quote cannot rescue the gas comparison in Jerome, since there is no yearly saving to recover it from.
Electric resistance heat in Jerome, compared
Plenty of homes in Jerome heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $1,296 a year comes back this way, enough that the 7.7-year payback clears the $10,000 premium comfortably within the equipment's life.
How Jerome compares nationally
Jerome lands at position 216 out of 3206 cities on heating severity (coldest is 1), and 2588 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
