Heat Pump Payback in Lebanon, OR
Is a heat pump worth it in Lebanon?
Lebanon technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $226 saved annually, for a payback of roughly 24.3 years. That's a technicality, not a recommendation, for anyone actually living in Lebanon.

How cold Lebanon actually gets
3988 heating degree days pile up here every year, so Lebanon has a real but manageable winter; the cooling side runs to 311 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 low of 16°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Lebanon 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. These numbers come from Corvallis Municipal Aprt, the closest NOAA station, 18.6 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 3,226 heating kilowatt-hours annually on top of cooling, totalling about $529 a year on electricity. Lebanon's gas rate of $16.71 per Mcf, applied to the 42 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $755 a year, against 15.14¢ per kWh for electricity. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $2,103 behind.
What would change Lebanon's answer
Gas would only overtake the heat pump in Lebanon if electricity rose past 22.5¢/kWh from 15.14¢, or gas fell under $11.26 per Mcf from $16.71. A useful quote test for Lebanon: the heat pump is worth it within a decade if it costs less than $2,260 more than replacing the furnace and AC, and within 7 years if the gap is under $1,582.
Electric resistance heat in Lebanon, compared
Not every home in Lebanon has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,061 a year, which recovers the extra $10,000 spent going electric in roughly 9.4 years.
Where Lebanon ranks in this dataset
Ranked against the other 3206 cities covered, Lebanon comes in at 1525 for heating severity, 1 would be the coldest place in the dataset, and 1929 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 Lebanon
Lebanon, Oregon is home to about 19,950 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 Lebanon, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
