Will a heat pump pay off in Red Oak, TX?
This one's marginal in Red Oak: it only clears if you stay long enough. $3,500 is what Red Oak would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $326 saved annually, for a payback of roughly 10.7 years. Whether that's worth it in Red Oak depends on how many years you expect to own the place.
The climate behind Red Oak's payback figure
1875 heating degree days pile up here every year, so Red Oak has a mild winter by US standards; the cooling side runs to 2786 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: 13.8°F here (record low 11.7°F), which works out to a seasonal COP of 3.03 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Red Oak — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,567 kWh a year to keep it warm, plus cooling, for a combined electric bill near $637 a year. The gas furnace it replaces burns roughly 20 Mcf a year at 19.42 per Mcf here, for a running cost near $962 a year (electricity here runs 16.15¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 41.5 years, leaving the 15-year total $1,385 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Red Oak heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $713 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 11.2 years.
How Red Oak compares nationally
Ranked against the other 3206 cities covered, Red Oak comes in at 2495 for heating severity — 1 would be the coldest place in the dataset — and 1983 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.
What to do with this number in Red Oak
About 19,365 people live in Red Oak, Texas, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Red Oak's 3.03 seasonal COP and payback figure. Red Oak'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.
