Heat Pump Payback in Forest Hill, TX
Heat pump vs. gas furnace in Forest Hill, TX
In Forest Hill, the extra upfront cost technically comes back, just not before the equipment wears out. 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 $338 of lower running costs every year, landing the payback clock at roughly 16.3 years. Forest Hill's own numbers say this pencils out only in theory, not in practice.

The climate behind Forest Hill's payback figure
Degree days tell the story here: Forest Hill racks up 1826 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2994 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 14°F, and the coldest daily reading in the 2024 station record was 10.4°F. That puts the seasonal coefficient of performance at 3.04 for the recommended cold-climate unit. The average winter here is gentle, but sizing follows the cold snaps, and 14°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 Forest Hill. These numbers come from Fort Worth Spinks Airport, the closest NOAA station, 7.1 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,521 kWh a year to keep it warm, plus cooling, for a combined electric bill near $658 a year. Forest Hill's gas rate of $19.42 per Mcf, applied to the 19 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $996 a year, against 16.15¢ per kWh for electricity. 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 $429 behind.
What would change Forest Hill's answer
This result holds unless electricity climbs above 190.9¢/kWh (it is 16.15¢ now) or gas drops below $1.64 per Mcf (now $19.42); past either point, gas becomes the cheaper fuel in Forest Hill. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $338 a year saved, a difference under $2,366 pays back within 7 years here, and under $3,380 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Forest Hill heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $715 a year, which recovers the extra $10,000 spent going electric in roughly 14 years.
Where Forest Hill ranks in this dataset
Forest Hill lands at position 2531 out of 3206 cities on heating severity (coldest is 1), and 2474 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.
