Heat Pump Payback in Starkville, MS
Heat pump vs. gas furnace in Starkville, MS
Starkville 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. Starkville's residents would see roughly $258 a year back in running costs, putting the payback around 21.3 years. Starkville's own numbers say this pencils out only in theory, not in practice.

Why Starkville's climate drives this number
2343 heating degree days pile up here every year, so Starkville has a mild winter by US standards; the cooling side runs to 2184 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 15.8°F here (coldest 2024 reading 6.8°F), which works out to a seasonal COP of 3.08 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 15.8°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 Starkville. Climate figures trace to the nearest NOAA station, George M Bryan Airport, 2.4 miles from Starkville.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,926 kWh a year to keep it warm, plus cooling, for a combined electric bill near $586 a year. The gas furnace it replaces burns roughly 24 Mcf a year at $16.64 per Mcf here, for a running cost near $844 a year including the old AC (electricity here runs 15.47¢/kWh). 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 $1,632 behind.
How sensitive Starkville's result is to prices
This result holds unless electricity climbs above 42.4¢/kWh (it is 15.47¢ now) or gas drops below $6.07 per Mcf (now $16.64); past either point, gas becomes the cheaper fuel in Starkville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $258 a year saved, a difference under $1,806 pays back within 7 years here, and under $2,580 within 10.
Electric resistance heat in Starkville, compared
Gas isn't universal in Starkville, 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. Switching saves about $770 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 13 years.
Where Starkville ranks in this dataset
Starkville lands at position 2259 out of 3206 cities on heating severity (coldest is 1), and 1551 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
