Heat Pump Payback in Smithville, MO
Is a heat pump worth it in Smithville?
The payback math works in Smithville on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Smithville's residents would see roughly $195 a year back in running costs, putting the payback around 28.2 years. Smithville's own numbers say this pencils out only in theory, not in practice.

The climate behind Smithville's payback figure
Smithville has a real but manageable winter, 4235 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1401 cooling degree days. Sizing runs off the design temperature, not the average day: -7.1°F here (coldest 2024 reading -16.1°F), which works out to a seasonal COP of 2.53 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Smithville sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in Smithville
A 2000-square-foot house here would pull roughly 4,239 heating kilowatt-hours annually on top of cooling, totalling about $697 a year on electricity. Smithville's gas rate of $14.94 per Mcf, applied to the 44 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $892 a year, against 12.83¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $2,578 behind.
How sensitive Smithville's result is to prices
This result holds unless electricity climbs above 18.2¢/kWh (it is 12.83¢ now) or gas drops below $10.52 per Mcf (now $14.94); past either point, gas becomes the cheaper fuel in Smithville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $195 a year saved, a difference under $1,365 pays back within 7 years here, and under $1,950 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Smithville, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Smithville's answer improves. About $912 a year comes back this way, enough that the 11-year payback clears the $10,000 premium comfortably within the equipment's life.
How Smithville compares nationally
