Is a heat pump worth it in San Angelo?
In San Angelo, the math is close enough that it comes down to how long you plan to stay. 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). That premium is recovered through $354 of lower running costs every year, landing the payback clock at roughly 9.9 years. Whether that's worth it in San Angelo depends on how many years you expect to own the place.
Why San Angelo's climate drives this number
Degree days tell the story here: San Angelo racks up 1737 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3253 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 16°F here (record low 10.9°F), which works out to a seasonal COP of 3.08 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in San Angelo — 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, SAN ANGELO REGIONAL/MATHS FIE, 6.7 miles from San Angelo.
The month-to-month numbers for San Angelo
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,428 kWh a year to keep it warm, plus cooling, for a combined electric bill near $679 a year. That compares with roughly 18 Mcf a year of gas at San Angelo's 19.42 per-Mcf rate — about $1,032 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 38.2 years, leaving the 15-year total $1,804 ahead.
Electric resistance heat in San Angelo, compared
Gas isn't universal in San Angelo — 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 $713 a year comes back this way, enough that the 11.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where San Angelo ranks in this dataset
San Angelo lands at position 2566 out of 3206 cities on heating severity (coldest is 1), and 340 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.
