Bellmead, TX: the heat pump payback math
This one's marginal in Bellmead: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $341 saved annually, for a payback of roughly 10.3 years. It's a genuine toss-up here — Bellmead's numbers don't point clearly either way.
Bellmead's weather, in the numbers that matter
1184 heating degree days pile up here every year, so Bellmead barely has a winter to speak of; the cooling side runs to 3590 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 17.6°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 14°F on file. Worked through the model, that's a seasonal COP of 3.12 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Bellmead — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, TSTC WACO, 2.7 miles from Bellmead.
The month-to-month numbers for Bellmead
Modelled on a typical 2000-square-foot house, the heat pump draws about 961 kWh a year to keep it warm, plus cooling, for a combined electric bill near $650 a year. Bellmead's gas rate of 19.42 per Mcf, applied to the 12 Mcf a year the furnace burns, puts its running cost near $991 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 39.6 years, for a 15-year net position $1,620 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Bellmead — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $586 a year comes back this way, enough that the 13.7-year payback clears the $8,000 premium comfortably within the equipment's life.
Bellmead against the rest of the country
Bellmead lands at position 2801 out of 3206 cities on heating severity (coldest is 1), and 3065 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.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Bellmead's 3.12 seasonal COP and payback figure. Bellmead's 17.6°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
