Heat Pump Payback in Nacogdoches, TX
Nacogdoches, TX: the heat pump payback math
Nacogdoches sits right on the fence, how long you'll own the house decides this one. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Nacogdoches's residents would see roughly $293 a year back in running costs, putting the payback around 10.2 years. It's a genuine toss-up here, Nacogdoches's numbers don't point clearly either way.

How cold Nacogdoches actually gets
Nacogdoches barely has a winter to speak of, 1366 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 2851 cooling degree days. Sizing runs off the design temperature, not the average day: 26.1°F here (coldest 2024 reading 14°F), which works out to a seasonal COP of 2.98 for the standard class of unit this climate calls for. Nacogdoches's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Angelina County Airport, the closest NOAA station, 26.7 miles out.
The yearly running costs in Nacogdoches
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,161 kWh a year to keep it warm, plus cooling, for a combined electric bill near $580 a year. Nacogdoches's gas rate of $19.42 per Mcf, applied to the 14 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $873 a year, against 16.15¢ per kWh for electricity. 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 $1,394 ahead.
How sensitive Nacogdoches's result is to prices
In Nacogdoches 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 Nacogdoches: the heat pump is worth it within a decade if it costs less than $2,930 more than replacing the furnace and AC, and within 7 years if the gap is under $2,051.
The other scenario: no gas furnace to begin with
Gas isn't universal in Nacogdoches, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $575 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $7,500 spent up front comes back in about 13 years.
Nacogdoches against the rest of the country
Ranked against the other 3206 cities covered, Nacogdoches comes in at 2743 for heating severity, 1 would be the coldest place in the dataset, and 1264 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.
