HeatPumpPayback

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 $3,500 after a $2,000 federal tax credit. That premium is recovered through $179 of lower running costs every year, landing the payback clock at roughly 19.5 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 (record low -5.8°F), which works out to a seasonal COP of 2.73 for the cold-climate class of unit this climate calls for. 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 FLOYD W JONES LEBANON, the closest NOAA station, 1.7 miles out.

The month-to-month numbers for 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 its running cost near $655 a year, against 12.83¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 75.3 years, for a 15-year net position $812 behind.

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. The saving here runs about $636 a year, which recovers the extra $8,000 spent going electric in roughly 12.6 years.

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 for 15,538 people 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.
