University Park, TX: the heat pump payback math
In University Park, 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 $360 of lower running costs every year, landing the payback clock at roughly 9.7 years. Whether that's worth it in University Park depends on how many years you expect to own the place.
The climate behind University Park's payback figure
1633 heating degree days pile up here every year, so University Park has a mild winter by US standards; the cooling side runs to 3396 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 10°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in University Park — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

University Park's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 1,321 heating kilowatt-hours annually on top of cooling, totalling about $681 a year on electricity. The gas furnace it replaces burns roughly 17 Mcf a year at 19.42 per Mcf here, for a running cost near $1,041 a year (electricity here runs 16.15¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 37.5 years, leaving the 15-year total $1,901 ahead.
Electric resistance heat in University Park, compared
Gas isn't universal in University Park — 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. The saving here runs about $698 a year, which recovers the extra $8,000 spent going electric in roughly 11.5 years.
University Park against the rest of the country
Among 3206 cities, University Park's winter puts it at rank 2629 for severity, while its size puts it at rank 1586 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 University Park's figure comes from
The methodology guide walks through exactly how University Park's 3.13 seasonal COP and the rest of this page's numbers get built. University Park's 18°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.
