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 $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $226 saved annually, for a payback of roughly 15.5 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 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. 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 its running cost near $755 a year, against 15.14¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 59.6 years, for a 15-year net position $103 behind.
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 $8,000 spent going electric in roughly 7.5 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.
