Heat Pump Payback in Alvin, TX
Will a heat pump pay off in Alvin, TX?
This one's marginal in Alvin: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Lower bills claw that back: about $318 saved annually, for a payback of roughly 9.4 years. It's a genuine toss-up here, Alvin's numbers don't point clearly either way.

How cold Alvin actually gets
795 heating degree days pile up here every year, so Alvin barely has a winter to speak of; the cooling side runs to 3633 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 32°F here (coldest 2024 reading 19.9°F), which works out to a seasonal COP of 3.15 for the standard class of unit this climate calls for. Alvin's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. Source: NOAA station Clover Field Airport, 6.6 miles from Alvin, the closest one on record.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 639 kWh a year to keep it warm, plus cooling, for a combined electric bill near $603 a year. The gas furnace it replaces burns roughly 8 Mcf a year at $19.42 per Mcf here, for a running cost near $921 a year including the old AC (electricity here runs 16.15¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,766 ahead.
How sensitive Alvin's result is to prices
In Alvin 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 Alvin: the heat pump is worth it within a decade if it costs less than $3,180 more than replacing the furnace and AC, and within 7 years if the gap is under $2,226.
The other scenario: no gas furnace to begin with
Gas isn't universal in Alvin, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Alvin's answer improves. The gap still doesn't close: the $7,500 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Alvin against the rest of the country
Alvin lands at position 2974 out of 3206 cities on heating severity (coldest is 1), and 1360 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.
