Everett, WA: the heat pump payback math
In Everett, the math is close enough that it comes down to how long you plan to stay. 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. That premium is recovered through $318 of lower running costs every year, landing the payback clock at roughly 11 years. Whether that's worth it in Everett depends on how many years you expect to own the place.
The climate behind Everett's payback figure
4489 heating degree days pile up here every year, so Everett has a real but manageable winter; the cooling side runs to 200 cooling degree days, where summers rarely ask much of an air conditioner. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12.9°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Everett 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, 5.8 miles from Everett.
The month-to-month numbers for Everett
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,632 kWh a year to keep it warm, plus cooling, for a combined electric bill near $543 a year. Everett's gas rate of 17.62 per Mcf, applied to the 47 Mcf a year the furnace burns, puts its running cost near $861 a year, against 14.27¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 42.4 years, for a 15-year net position $1,273 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Everett — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Everett's answer improves. About $1,116 a year comes back this way, enough that the 7.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Everett ranks in this dataset
Everett lands at position 1200 out of 3206 cities on heating severity (coldest is 1), and 278 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
