Heat Pump Payback in Monett, MO
Monett, MO: the heat pump payback math
In Monett, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Monett would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $226 saved annually, for a payback of roughly 24.3 years. Monett's own numbers say this pencils out only in theory, not in practice.

The climate behind Monett's payback figure
3186 heating degree days pile up here every year, so Monett has a real but manageable winter; the cooling side runs to 1427 cooling degree days, where summers are hot enough that cooling matters as much as heating. 10.4°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -0.4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.95 on the cold-climate unit fit for this climate. Monett 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
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,735 kWh a year to keep it warm, plus cooling, for a combined electric bill near $507 a year. The gas furnace it replaces burns roughly 33 Mcf a year at $14.94 per Mcf here, for a running cost near $733 a year including the old AC (electricity here runs 12.83¢/kWh). 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 $2,109 behind.
How sensitive Monett's result is to prices
This result holds unless electricity climbs above 23.6¢/kWh (it is 12.83¢ now) or gas drops below $8.13 per Mcf (now $14.94); past either point, gas becomes the cheaper fuel in Monett. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $226 a year saved, a difference under $1,582 pays back within 7 years here, and under $2,260 within 10.
Electric resistance heat in Monett, compared
Not every home in Monett has gas service. 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 $765 a year, which recovers the extra $10,000 spent going electric in roughly 13.1 years.
How Monett compares nationally
Ranked against the other 3206 cities covered, Monett comes in at 1856 for heating severity, 1 would be the coldest place in the dataset, and 3180 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Where Monett's figure comes from
Every constant behind this page, the 2.95 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Monett's 10.4°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
