Heat Pump Payback in Grandview, WA
Should Grandview switch to a heat pump?
The payback math works in Grandview on paper, past the equipment's own working life. $5,500 is what Grandview would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $323 saved annually, for a payback of roughly 17 years. Grandview's own numbers say this pencils out only in theory, not in practice.

The climate behind Grandview's payback figure
4148 heating degree days pile up here every year, so Grandview has a real but manageable winter; the cooling side runs to 1305 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 7.7°F here (coldest 2024 reading 1°F), which works out to a seasonal COP of 2.88 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Grandview, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Grandview's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,647 heating kilowatt-hours annually on top of cooling, totalling about $679 a year on electricity. Grandview's gas rate of $17.62 per Mcf, applied to the 43 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,003 a year, against 14.27¢ 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 $650 behind.
The break-even point in Grandview
This result holds unless electricity climbs above 24.8¢/kWh (it is 14.27¢ now) or gas drops below $10.14 per Mcf (now $17.62); past either point, gas becomes the cheaper fuel in Grandview. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $323 a year saved, a difference under $2,261 pays back within 7 years here, and under $3,230 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Grandview, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $1,061 a year comes back this way, enough that the 9.4-year payback clears the $10,000 premium comfortably within the equipment's life.
How Grandview compares nationally
Grandview lands at position 1432 out of 3206 cities on heating severity (coldest is 1), and 2878 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

More on how this number was built
Every constant behind this page, the 2.88 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Grandview's 7.7°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.
