Heat Pump Payback in Angleton, TX
Will a heat pump pay off in Angleton, TX?
This one's marginal in Angleton: it only clears if you stay long enough. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. Angleton's residents would see roughly $291 a year back in running costs, putting the payback around 10.3 years. It's a genuine toss-up here, Angleton's numbers don't point clearly either way.

How cold Angleton actually gets
Angleton barely has a winter to speak of, 812 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 3265 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 30°F, and the coldest daily reading in the 2024 station record was 19°F. That puts the seasonal coefficient of performance at 3.09 for the recommended standard unit. Angleton's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

The yearly running costs in Angleton
A 2000-square-foot house here would pull roughly 665 heating kilowatt-hours annually on top of cooling, totalling about $557 a year on electricity. Angleton's gas rate of $19.42 per Mcf, applied to the 8 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $848 a year, against 16.15¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,358 ahead.
How sensitive Angleton's result is to prices
In Angleton the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Angleton: the heat pump is worth it within a decade if it costs less than $2,910 more than replacing the furnace and AC, and within 7 years if the gap is under $2,037.
If your home heats with electric baseboard instead of gas
Not every home in Angleton has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Angleton against the rest of the country
Ranked against the other 3206 cities covered, Angleton comes in at 2963 for heating severity, 1 would be the coldest place in the dataset, and 1850 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
