Should Woodburn switch to a heat pump?
This one's marginal in Woodburn: it only clears if you stay long enough. $3,500 is what Woodburn 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. Lower bills claw that back: about $256 saved annually, for a payback of roughly 13.7 years. Whether that's worth it in Woodburn depends on how many years you expect to own the place.
Why Woodburn's climate drives this number
4286 heating degree days pile up here every year, so Woodburn has a real but manageable winter; the cooling side runs to 518 cooling degree days, where summers add a moderate cooling load. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 16°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Woodburn 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
Electricity use for heating alone comes out to about 3,467 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $592 a year. That compares with roughly 45 Mcf a year of gas at Woodburn's 16.71 per-Mcf rate — about $848 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 52.8 years, leaving the 15-year total $336 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Woodburn — 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 $1,153 a year comes back this way, enough that the 6.9-year payback clears the $8,000 premium comfortably within the equipment's life.
Woodburn against the rest of the country
Ranked against the other 3206 cities covered, Woodburn comes in at 1335 for heating severity — 1 would be the coldest place in the dataset — and 1342 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
What to do with this number in Woodburn
About 30,449 people live in Woodburn, Oregon, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
