Heat Pump Payback in Lebanon, MO
Heat pump vs. gas furnace in Lebanon, MO
Lebanon technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $179 of lower running costs every year, landing the payback clock at roughly 30.7 years. Lebanon's own numbers say this pencils out only in theory, not in practice.

Why Lebanon's climate drives this number
Lebanon has a mild winter by US standards, 2701 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1413 cooling degree days. Sizing runs off the design temperature, not the average day: 1.4°F here (coldest 2024 reading -5.8°F), which works out to a seasonal COP of 2.73 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 1.4°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Lebanon. These numbers come from Floyd W Jones Lebanon, the closest NOAA station, 1.7 miles out.
The yearly running costs in Lebanon
Electricity use for heating alone comes out to about 2,505 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $476 a year. Lebanon's gas rate of $14.94 per Mcf, applied to the 28 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $655 a year, against 12.83¢ 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 $2,812 behind.
The break-even point in Lebanon
This result holds unless electricity climbs above 22.4¢/kWh (it is 12.83¢ now) or gas drops below $8.57 per Mcf (now $14.94); past either point, gas becomes the cheaper fuel in Lebanon. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $179 a year saved, a difference under $1,253 pays back within 7 years here, and under $1,790 within 10.
Electric resistance heat in Lebanon, compared
Gas isn't universal in Lebanon, 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. Even against resistance heat, the running-cost gap here isn't enough to clear the $10,000 incremental cost within the equipment's 15-year life.
Where Lebanon ranks in this dataset
Among 3206 cities, Lebanon's winter puts it at rank 2036 for severity, while its size puts it at rank 2343 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
Next step if you live in Lebanon
About 15,538 people live in Lebanon, Missouri, 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.
Ask a local HVAC contractor for a quote before committing either way.
More on how this number was built
Every constant behind this page, the 2.73 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Lebanon's 1.4°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
