Heat Pump Payback in Midlothian, TX
Heat pump vs. gas furnace in Midlothian, TX
Midlothian 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 $305 of lower running costs every year, landing the payback clock at roughly 18.1 years. Midlothian's own numbers say this pencils out only in theory, not in practice.

The climate behind Midlothian's payback figure
1624 heating degree days pile up here every year, so Midlothian has a mild winter by US standards; the cooling side runs to 2729 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 13.8°F here (coldest 2024 reading 11.3°F), which works out to a seasonal COP of 3.03 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 13.8°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 Midlothian. Climate figures trace to the nearest NOAA station, Mid-Way Regional Airport, 4.6 miles from Midlothian.
Midlothian's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,357 kWh a year to keep it warm, plus cooling, for a combined electric bill near $595 a year. The gas furnace it replaces burns roughly 17 Mcf a year at $19.42 per Mcf here, for a running cost near $900 a year including the old AC (electricity here runs 16.15¢/kWh). If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $930 behind.
How sensitive Midlothian's result is to prices
This result holds unless electricity climbs above 223.1¢/kWh (it is 16.15¢ now) or gas drops below $1.41 per Mcf (now $19.42); past either point, gas becomes the cheaper fuel in Midlothian. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $305 a year saved, a difference under $2,135 pays back within 7 years here, and under $3,050 within 10.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Midlothian, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. 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.
Midlothian against the rest of the country
Ranked against the other 3206 cities covered, Midlothian comes in at 2638 for heating severity, 1 would be the coldest place in the dataset, and 934 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
