American Fork, UT: the heat pump payback math
American Fork technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. American Fork's residents would see roughly $50 a year back in running costs, putting the payback around 69.5 years. That's a technicality, not a recommendation, for anyone actually living in American Fork.
How cold American Fork actually gets
5203 heating degree days pile up here every year, so American Fork has a cold winter that leans hard on heating equipment; the cooling side runs to 1246 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 12.9°F, against a record low of 12°F. That puts the seasonal coefficient of performance at 3.01 for the recommended cold-climate unit. A cold-climate unit is the right call in American Fork — 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 PROVO MUNICIPAL AIRPORT, the closest NOAA station, 11.6 miles out.
The month-to-month numbers for American Fork
Electricity use for heating alone comes out to about 4,377 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $714 a year. That compares with roughly 54 Mcf a year of gas at American Fork's 10.19 per-Mcf rate — about $764 a year — against a local electricity rate of 13.12¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 267.9 years, leaving the 15-year total $2,744 behind.
Electric resistance heat in American Fork, compared
Not every home in American Fork has gas service. Swap the comparison to resistance heat instead of gas, and American Fork's answer improves. About $1,227 a year comes back this way, enough that the 6.5-year payback clears the $8,000 premium comfortably within the equipment's life.
How American Fork compares nationally
Ranked against the other 3206 cities covered, American Fork comes in at 565 for heating severity — 1 would be the coldest place in the dataset — and 991 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in American Fork
American Fork, Utah is home to about 41,298 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In American Fork, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Nothing above is a black box: the methodology guide shows the full arithmetic behind American Fork's 3.01 seasonal COP and payback figure. American Fork's 12.9°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
