Heat Pump Payback in Washougal, WA
Heat pump vs. gas furnace in Washougal, WA
Washougal 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. That premium is recovered through $305 of lower running costs every year, landing the payback clock at roughly 18 years. Washougal's own numbers say this pencils out only in theory, not in practice.

Why Washougal's climate drives this number
Degree days tell the story here: Washougal racks up 3827 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 635 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 19°F here (coldest 2024 reading 14°F), which works out to a seasonal COP of 3.16 for the cold-climate class of unit this climate calls for. Washougal 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 Portland-Troutdale Airport, the closest NOAA station, 3.7 miles out.
Washougal's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,067 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $515 a year. That compares with roughly 40 Mcf a year of gas at Washougal's $17.62 per-Mcf rate, about $820 a year with the old AC included, against a local electricity rate of 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 $927 behind.
How sensitive Washougal's result is to prices
This result holds unless electricity climbs above 25.2¢/kWh (it is 14.27¢ now) or gas drops below $9.97 per Mcf (now $17.62); past either point, gas becomes the cheaper fuel in Washougal. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $305 a year saved, a difference under $2,135 pays back within 7 years here, and under $3,050 within 10.
Electric resistance heat in Washougal, compared
Gas isn't universal in Washougal, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Washougal's answer improves. About $985 a year comes back this way, enough that the 10.1-year payback clears the $10,000 premium comfortably within the equipment's life.
How Washougal compares nationally
Washougal lands at position 1633 out of 3206 cities on heating severity (coldest is 1), and 2103 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 3.16 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Washougal's 19°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
