Waxahachie, TX: the heat pump payback math
In Waxahachie, 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. Lower bills claw that back: about $305 saved annually, for a payback of roughly 11.5 years. Whether that's worth it in Waxahachie depends on how many years you expect to own the place.
The climate behind Waxahachie's payback figure
1624 heating degree days pile up here every year, so Waxahachie has a mild winter by US standards; the cooling side runs to 2729 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 13.8°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 11.3°F on file. Worked through the model, that's a seasonal COP of 3.03 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Waxahachie — 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, MID-WAY REGIONAL AIRPORT, 5.4 miles from Waxahachie.
Waxahachie's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 1,357 heating kilowatt-hours annually on top of cooling, totalling about $595 a year on electricity. That compares with roughly 17 Mcf a year of gas at Waxahachie's 19.42 per-Mcf rate — about $900 a year — against a local electricity rate of 16.15¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 44.3 years, leaving the 15-year total $1,070 ahead.
Electric resistance heat in Waxahachie, compared
Gas isn't universal in Waxahachie — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Waxahachie's answer improves. About $640 a year comes back this way, enough that the 12.5-year payback clears the $8,000 premium comfortably within the equipment's life.
How Waxahachie compares nationally
Among 3206 cities, Waxahachie's winter puts it at rank 2637 for severity, while its size puts it at rank 846 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Waxahachie's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Waxahachie's 3.03 seasonal COP and payback figure. Waxahachie's 13.8°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.
