Will a heat pump pay off in Grants Pass, OR?
Grants Pass sits right on the fence — how long you'll own the house decides this one. $3,500 is what Grants Pass 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. Grants Pass's residents would see roughly $296 a year back in running costs, putting the payback around 11.8 years. It's a genuine toss-up here — Grants Pass's numbers don't point clearly either way.
Grants Pass's weather, in the numbers that matter
3973 heating degree days pile up here every year, so Grants Pass has a real but manageable winter; the cooling side runs to 1095 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 23°F here (record low 19°F), which works out to a seasonal COP of 3.25 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Grants Pass — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from ROGUE VALLEY INTL-MEDFORD AIR, the closest NOAA station, 23.5 miles out.
Grants Pass's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,095 kWh a year to keep it warm, plus cooling, for a combined electric bill near $610 a year. That compares with roughly 41 Mcf a year of gas at Grants Pass's 16.71 per-Mcf rate — about $906 a year — against a local electricity rate of 15.14¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 45.6 years, leaving the 15-year total $944 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Grants Pass — 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. About $1,128 a year comes back this way, enough that the 7.1-year payback clears the $8,000 premium comfortably within the equipment's life.
How Grants Pass compares nationally
Grants Pass lands at position 1544 out of 3206 cities on heating severity (coldest is 1), and 1048 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 Grants Pass
Grants Pass, Oregon is home to about 39,468 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 Grants Pass, nothing is lost by holding off until the current equipment genuinely fails.

Where Grants Pass's figure comes from
The methodology guide walks through exactly how Grants Pass's 3.25 seasonal COP and the rest of this page's numbers get built. Grants Pass's 23°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
