Will a heat pump pay off in Independence, OR?
This one's marginal in Independence: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $243 saved annually, for a payback of roughly 14.4 years. Whether that's worth it in Independence depends on how many years you expect to own the place.
The climate behind Independence's payback figure
3970 heating degree days pile up here every year, so Independence has a real but manageable winter; the cooling side runs to 686 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 16°F here (record low 15.8°F), which works out to a seasonal COP of 3.08 for the cold-climate class of unit this climate calls for. Independence 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.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,264 kWh a year to keep it warm, plus cooling, for a combined electric bill near $583 a year. Independence's gas rate of 16.71 per Mcf, applied to the 41 Mcf a year the furnace burns, puts its running cost near $825 a year, against 15.14¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 55.6 years, leaving the 15-year total $142 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Independence 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. About $1,074 a year comes back this way, enough that the 7.4-year payback clears the $8,000 premium comfortably within the equipment's life.
Independence against the rest of the country
Independence lands at position 1552 out of 3206 cities on heating severity (coldest is 1), and 3129 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Independence's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Independence's 3.08 seasonal COP and payback figure. Independence's 16°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
