Will a heat pump pay off in Troutdale, OR?
In Troutdale, the math is close enough that it comes down to how long you plan to stay. 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. Troutdale's residents would see roughly $244 a year back in running costs, putting the payback around 14.3 years. Whether that's worth it in Troutdale depends on how many years you expect to own the place.
Why Troutdale's climate drives this number
Degree days tell the story here: Troutdale racks up 3827 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 635 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 19°F here (record low 14°F), which works out to a seasonal COP of 3.16 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Troutdale sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from PORTLAND-TROUTDALE AIRPORT, the closest NOAA station, 1.1 miles out.
Troutdale's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,067 heating kilowatt-hours annually on top of cooling, totalling about $546 a year on electricity. Troutdale's gas rate of 16.71 per Mcf, applied to the 40 Mcf a year the furnace burns, puts its running cost near $791 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 55.2 years, for a 15-year net position $165 ahead.
The other scenario: no gas furnace to begin with
Not every home in Troutdale has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $1,045 a year, which recovers the extra $8,000 spent going electric in roughly 7.7 years.
Troutdale against the rest of the country
Among 3206 cities, Troutdale's winter puts it at rank 1634 for severity, while its size puts it at rank 2320 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Every constant behind this page — the 3.16 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Troutdale'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.
