Will a heat pump pay off in Spokane Valley, WA?
In Spokane Valley, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $311 of lower running costs every year, landing the payback clock at roughly 11.3 years. Whether that's worth it in Spokane Valley depends on how many years you expect to own the place.
Why Spokane Valley's climate drives this number
Spokane Valley has a cold winter that leans hard on heating equipment — 5519 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 804 cooling degree days. Sizing runs off the design temperature, not the average day: -2°F here (record low -8°F), which works out to a seasonal COP of 2.65 for the cold-climate class of unit this climate calls for. Spokane Valley needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from FELTS FIELD AIRPORT, the closest NOAA station, 4.3 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 5,274 heating kilowatt-hours annually on top of cooling, totalling about $850 a year on electricity. That compares with roughly 57 Mcf a year of gas at Spokane Valley's 17.62 per-Mcf rate — about $1,161 a year — against a local electricity rate of 14.27¢/kWh. Buy it outright, not incrementally, and payback stretches to 43.4 years; over 15 years the net position sits $1,167 ahead.
Electric resistance heat in Spokane Valley, compared
Not every home in Spokane Valley 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. Switching saves about $1,293 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 6.2 years.
Where Spokane Valley ranks in this dataset
Ranked against the other 3206 cities covered, Spokane Valley comes in at 362 for heating severity — 1 would be the coldest place in the dataset — and 300 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Spokane Valley's 2.65 seasonal COP and payback figure. Spokane Valley's -2°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
