Fairview, OR: the heat pump payback math
This one's marginal in Fairview: it only clears if you stay long enough. $3,500 is what Fairview would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. That premium is recovered through $244 of lower running costs every year, landing the payback clock at roughly 14.3 years. It's a genuine toss-up here — Fairview's numbers don't point clearly either way.
How cold Fairview actually gets
3827 heating degree days pile up here every year, so Fairview has a real but manageable winter; the cooling side runs to 635 cooling degree days, where summers add a moderate cooling load. 19°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 14°F on file. Worked through the model, that's a seasonal COP of 3.16 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Fairview — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Fairview'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 $546 a year. The gas furnace it replaces burns roughly 40 Mcf a year at 16.71 per Mcf here, for a running cost near $791 a year (electricity here runs 15.14¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 55.2 years, leaving the 15-year total $165 ahead.
Electric resistance heat in Fairview, compared
Not every home in Fairview has gas service. Swap the comparison to resistance heat instead of gas, and Fairview's answer improves. The saving here runs about $1,045 a year, which recovers the extra $8,000 spent going electric in roughly 7.7 years.
How Fairview compares nationally
Fairview lands at position 1636 out of 3206 cities on heating severity (coldest is 1), and 3027 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Fairview
Fairview, Oregon is home to about 10,796 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Fairview, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Fairview's 3.16 seasonal COP and payback figure. Fairview's 19°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.
