HeatPumpPayback

Is a heat pump worth it in Molalla?

Molalla sits right on the fence — how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. That premium is recovered through $256 of lower running costs every year, landing the payback clock at roughly 13.7 years. Whether that's worth it in Molalla depends on how many years you expect to own the place.

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 record low of 16°F on file. 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 its running cost near $848 a year, against 15.14¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 52.8 years, for a 15-year net position $336 ahead.

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 $8,000 spent going electric in roughly 6.9 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.

About 10,134 people live in Molalla, Oregon, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

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.
