Will a heat pump pay off in Glenn Heights, TX?
In Glenn Heights, 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 $305 of lower running costs every year, landing the payback clock at roughly 11.5 years. Whether that's worth it in Glenn Heights depends on how many years you expect to own the place.
The climate behind Glenn Heights's payback figure
1624 heating degree days pile up here every year, so Glenn Heights has a mild winter by US standards; the cooling side runs to 2729 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 13.8°F, against a record low of 11.3°F. That puts the seasonal coefficient of performance at 3.03 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Glenn Heights sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from MID-WAY REGIONAL AIRPORT, the closest NOAA station, 7.4 miles out.
Glenn Heights's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 1,357 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $595 a year. That compares with roughly 17 Mcf a year of gas at Glenn Heights's 19.42 per-Mcf rate — about $900 a year — against a local electricity rate of 16.15¢/kWh. Buy it outright, not incrementally, and payback stretches to 44.3 years; over 15 years the net position sits $1,070 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Glenn Heights heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $640 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 12.5 years.
How Glenn Heights compares nationally
Glenn Heights lands at position 2639 out of 3206 cities on heating severity (coldest is 1), and 1948 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.

More on how this number was built
Every constant behind this page — the 3.03 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Glenn Heights's 13.8°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.
