Heat Pump Payback in West Haven, UT
Is a heat pump worth it in West Haven?
In West Haven, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Lower bills claw that back: about $69 saved annually, for a payback of roughly 79.4 years. West Haven's own numbers say this pencils out only in theory, not in practice.

The climate behind West Haven's payback figure
4722 heating degree days pile up here every year, so West Haven has a real but manageable winter; the cooling side runs to 1811 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 9°F, and the coldest daily reading in the 2024 station record was 6.1°F. That puts the seasonal coefficient of performance at 2.92 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, West Haven sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,095 kWh a year to keep it warm, plus cooling, for a combined electric bill near $740 a year. West Haven's gas rate of $10.19 per Mcf, applied to the 49 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $809 a year, against 13.12¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $4,461 behind.
What would change West Haven's answer
This result holds unless electricity climbs above 15.2¢/kWh (it is 13.12¢ now) or gas drops below $8.78 per Mcf (now $10.19); past either point, gas becomes the cheaper fuel in West Haven. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $69 a year saved, a difference under $483 pays back within 7 years here, and under $690 within 10.
The other scenario: no gas furnace to begin with
Not every home in West Haven has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,137 a year, which recovers the extra $10,000 spent going electric in roughly 8.8 years.
West Haven against the rest of the country
Among 3206 cities, West Haven's winter puts it at rank 1007 for severity, while its size puts it at rank 1631 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where West Haven's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind West Haven's 2.92 seasonal COP and payback figure. West Haven's 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.
