Heat pump vs. gas furnace in Forest Hill, TX
In Forest Hill, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. That premium is recovered through $338 of lower running costs every year, landing the payback clock at roughly 10.4 years. Whether that's worth it in Forest Hill depends on how many years you expect to own the place.
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, against a record low of 10.4°F. That puts the seasonal coefficient of performance at 3.04 for the recommended cold-climate unit. A cold-climate unit is the right call in Forest Hill — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. 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 its running cost near $996 a year, against 16.15¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 39.9 years, for a 15-year net position $1,571 ahead.
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 $8,000 spent going electric in roughly 11.2 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.
