Heat Pump Payback in Kenmore, WA
Heat pump vs. gas furnace in Kenmore, WA
The payback math works in Kenmore on paper, past the equipment's own working life. 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 $318 saved annually, for a payback of roughly 17.3 years. Kenmore's own numbers say this pencils out only in theory, not in practice.

The climate behind Kenmore's payback figure
4489 heating degree days pile up here every year, so Kenmore has a real but manageable winter; the cooling side runs to 200 cooling degree days, where summers rarely ask much of an air conditioner. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 18°F, and the coldest daily reading in the 2024 station record was 12.9°F. That puts the seasonal coefficient of performance at 3.13 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Kenmore sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Snohomish Co (Paine Fd) AP, 11 miles from Kenmore.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,632 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $543 a year. The gas furnace it replaces burns roughly 47 Mcf a year at $17.62 per Mcf here, for a running cost near $861 a year including the old AC (electricity here runs 14.27¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $727 behind.
The break-even point in Kenmore
This result holds unless electricity climbs above 23.3¢/kWh (it is 14.27¢ now) or gas drops below $10.81 per Mcf (now $17.62); past either point, gas becomes the cheaper fuel in Kenmore. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $318 a year saved, a difference under $2,226 pays back within 7 years here, and under $3,180 within 10.
Electric resistance heat in Kenmore, compared
Not every home in Kenmore 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 $1,116 a year, which recovers the extra $10,000 spent going electric in roughly 9 years.
How Kenmore compares nationally
Kenmore lands at position 1207 out of 3206 cities on heating severity (coldest is 1), and 1656 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
