Heat Pump Payback in Bonham, TX
Will a heat pump pay off in Bonham, TX?
Bonham 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. Bonham's residents would see roughly $338 a year back in running costs, putting the payback around 16.3 years. Bonham's own numbers say this pencils out only in theory, not in practice.

Why Bonham's climate drives this number
Degree days tell the story here: Bonham racks up 2175 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2731 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 12.2°F, and the coldest daily reading in the 2024 station record was 8.6°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. The average winter here is gentle, but sizing follows the cold snaps, and 12.2°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 Bonham. Climate figures trace to the nearest NOAA station, Eaker Field Airport, 27.1 miles from Bonham.
The yearly running costs in Bonham
Electricity use for heating alone comes out to about 1,842 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $674 a year. That compares with roughly 23 Mcf a year of gas at Bonham's $19.42 per-Mcf rate, about $1,012 a year with the old AC included, against a local electricity rate of 16.15¢/kWh. 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 $430 behind.
The break-even point in Bonham
This result holds unless electricity climbs above 69.7¢/kWh (it is 16.15¢ now) or gas drops below $4.50 per Mcf (now $19.42); past either point, gas becomes the cheaper fuel in Bonham. 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.
Electric resistance heat in Bonham, compared
Plenty of homes in Bonham 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. About $788 a year comes back this way, enough that the 12.7-year payback clears the $10,000 premium comfortably within the equipment's life.
Bonham against the rest of the country
Bonham lands at position 2348 out of 3206 cities on heating severity (coldest is 1), and 2965 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.
