Heat Pump Payback in Molalla, OR
Is a heat pump worth it in Molalla?
Molalla 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 $256 of lower running costs every year, landing the payback clock at roughly 21.5 years. Molalla's own numbers say this pencils out only in theory, not in practice.

Why Molalla's climate drives this number
Degree days tell the story here: Molalla racks up 4286 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 518 cooling degree days on the cooling side. 18°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 16°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Molalla 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. Climate figures trace to the nearest NOAA station, Aurora State Airport, 11.3 miles from Molalla.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,467 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $592 a year. Molalla's gas rate of $16.71 per Mcf, applied to the 45 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $848 a year, against 15.14¢ per kWh for electricity. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,664 behind.
How sensitive Molalla's result is to prices
This result holds unless electricity climbs above 23.0¢/kWh (it is 15.14¢ now) or gas drops below $10.98 per Mcf (now $16.71); past either point, gas becomes the cheaper fuel in Molalla. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $256 a year saved, a difference under $1,792 pays back within 7 years here, and under $2,560 within 10.
Electric resistance heat in Molalla, compared
Not every home in Molalla has gas service. Swap the comparison to resistance heat instead of gas, and Molalla's answer improves. The saving here runs about $1,153 a year, which recovers the extra $10,000 spent going electric in roughly 8.7 years.
Molalla against the rest of the country
Ranked against the other 3206 cities covered, Molalla comes in at 1343 for heating severity, 1 would be the coldest place in the dataset, and 3174 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Where Molalla's figure comes from
The methodology guide walks through exactly how Molalla's 3.13 seasonal COP and the rest of this page's numbers get built. Molalla's 18°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.
