Is a heat pump worth it in Oregon?

In Oregon, a heat pump would cost more to run each year than what you have now. $3,500 is what Oregon 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. Unfortunately the electric bill outweighs the gas bill it replaces by about $403 a year here, so the extra spend stays unrecovered. That's Oregon's own climate and rates talking, not a hedge or a caveat.

How cold Oregon actually gets

Degree days tell the story here: Oregon racks up 5775 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 761 cooling degree days on the cooling side. -9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -11°F on file. Worked through the model, that's a seasonal COP of 2.48 on the cold-climate unit fit for this climate. Oregon 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.

The month-to-month numbers for Oregon

Modelled on a typical 2000-square-foot house, the heat pump draws about 5,896 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,235 a year. Oregon's gas rate of 10.74 per Mcf, applied to the 60 Mcf a year the furnace burns, puts its running cost near $832 a year, against 18.87¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $9,545 behind.

Electric resistance heat in Oregon, compared

Plenty of homes in Oregon heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,710 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4.7 years.

Oregon against the rest of the country

Among 3206 cities, Oregon's winter puts it at rank 292 for severity, while its size puts it at rank 2823 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

What to do with this number in Oregon

Oregon, Wisconsin is home to about 11,895 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 Oregon, nothing is lost by holding off until the current equipment genuinely fails.

Where Oregon's figure comes from

Every constant behind this page — the 2.48 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a -9°F design temperature, Oregon sits in cold-climate territory; the guide to that class of unit explains why.
