Heat Pump Payback in Ellensburg, WA
Is a heat pump worth it in Ellensburg?
Ellensburg 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 $5,500. Ellensburg's residents would see roughly $297 a year back in running costs, putting the payback around 18.5 years. Ellensburg's own numbers say this pencils out only in theory, not in practice.

Why Ellensburg's climate drives this number
Degree days tell the story here: Ellensburg racks up 5751 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 746 cooling degree days on the cooling side. -5.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.58 on the cold-climate unit fit for this climate. Ellensburg 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.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 5,644 heating kilowatt-hours annually on top of cooling, totalling about $896 a year on electricity. The gas furnace it replaces burns roughly 60 Mcf a year at $17.62 per Mcf here, for a running cost near $1,193 a year including the old AC (electricity here runs 14.27¢/kWh). 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 $1,043 behind.
The break-even point in Ellensburg
This result holds unless electricity climbs above 19.9¢/kWh (it is 14.27¢ now) or gas drops below $12.66 per Mcf (now $17.62); past either point, gas becomes the cheaper fuel in Ellensburg. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $297 a year saved, a difference under $2,079 pays back within 7 years here, and under $2,970 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in Ellensburg heat with electricity alone, no gas line involved. 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 $1,320 a year, which recovers the extra $10,000 spent going electric in roughly 7.6 years.
Ellensburg against the rest of the country
Ellensburg lands at position 299 out of 3206 cities on heating severity (coldest is 1), and 1847 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
