Heat Pump Payback in Silverton, OR
Should Silverton switch to a heat pump?
In Silverton, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. That premium is recovered through $243 of lower running costs every year, landing the payback clock at roughly 22.7 years. Silverton's own numbers say this pencils out only in theory, not in practice.

Why Silverton's climate drives this number
Degree days tell the story here: Silverton racks up 3970 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 686 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 16°F, and the coldest daily reading in the 2024 station record was 15.8°F. That puts the seasonal coefficient of performance at 3.08 for the recommended cold-climate unit. Silverton 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, McNary Field Airport, 12.7 miles from Silverton.
The yearly running costs in Silverton
A 2000-square-foot house here would pull roughly 3,264 heating kilowatt-hours annually on top of cooling, totalling about $583 a year on electricity. That compares with roughly 41 Mcf a year of gas at Silverton's $16.71 per-Mcf rate, about $825 a year with the old AC included, against a local electricity rate of 15.14¢/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 $1,858 behind.
How sensitive Silverton's result is to prices
This result holds unless electricity climbs above 23.3¢/kWh (it is 15.14¢ now) or gas drops below $10.84 per Mcf (now $16.71); past either point, gas becomes the cheaper fuel in Silverton. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $243 a year saved, a difference under $1,701 pays back within 7 years here, and under $2,430 within 10.
Electric resistance heat in Silverton, compared
Plenty of homes in Silverton 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. Switching saves about $1,074 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 9.3 years.
Where Silverton ranks in this dataset
Ranked against the other 3206 cities covered, Silverton comes in at 1551 for heating severity, 1 would be the coldest place in the dataset, and 3109 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
What to do with this number in Silverton
About 10,391 people live in Silverton, 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.
Ask a local HVAC contractor for a quote before committing either way.
