Heat Pump Payback in Stephenville, TX
Heat pump vs. gas furnace in Stephenville, TX
In Stephenville, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Stephenville would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $317 of lower running costs every year, landing the payback clock at roughly 17.3 years. Stephenville's own numbers say this pencils out only in theory, not in practice.

Why Stephenville's climate drives this number
Stephenville has a mild winter by US standards, 1866 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 2667 cooling degree days. Sizing runs off the design temperature, not the average day: 14°F here (coldest 2024 reading 9.9°F), which works out to a seasonal COP of 3.04 for the cold-climate class of unit this climate calls for. 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 Stephenville. These numbers come from Clark Field Municipal Airport, the closest NOAA station, 2.4 miles out.
The yearly running costs in Stephenville
Electricity use for heating alone comes out to about 1,554 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $618 a year. Stephenville'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 $936 a year, against 16.15¢ per kWh for electricity. 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 $740 behind.
The break-even point in Stephenville
This result holds unless electricity climbs above 101.5¢/kWh (it is 16.15¢ now) or gas drops below $3.09 per Mcf (now $19.42); past either point, gas becomes the cheaper fuel in Stephenville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $317 a year saved, a difference under $2,219 pays back within 7 years here, and under $3,170 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Stephenville heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $703 a year comes back this way, enough that the 14.2-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Stephenville ranks in this dataset
