Heat Pump Payback in West Linn, OR
West Linn, OR: the heat pump payback math
The payback math works in West Linn on paper, past the equipment's own working life. 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. That's a technicality, not a recommendation, for anyone actually living in West Linn.

How cold West Linn actually gets
Degree days tell the story here: West Linn 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. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 18°F, and the coldest daily reading in the 2024 station record was 16°F. That puts the seasonal coefficient of performance at 3.13 for the recommended cold-climate unit. A cold-climate unit is the right call in West Linn, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The yearly running costs in West Linn
A 2000-square-foot house here would pull roughly 3,467 heating kilowatt-hours annually on top of cooling, totalling about $592 a year on electricity. West Linn'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. 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 $1,664 behind.
What would change West Linn's answer
Gas would only overtake the heat pump in West Linn if electricity rose past 23.0¢/kWh from 15.14¢, or gas fell under $10.98 per Mcf from $16.71. A useful quote test for West Linn: the heat pump is worth it within a decade if it costs less than $2,560 more than replacing the furnace and AC, and within 7 years if the gap is under $1,792.
If your home heats with electric baseboard instead of gas
Gas isn't universal in West Linn, 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. Switching saves about $1,153 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 8.7 years.
How West Linn compares nationally
Among 3206 cities, West Linn's winter puts it at rank 1339 for severity, while its size puts it at rank 1501 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

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