Should Corinth switch to a heat pump?
This one's marginal in Corinth: it only clears if you stay long enough. $3,500 is what Corinth 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 $350 saved annually, for a payback of roughly 10 years. Whether that's worth it in Corinth depends on how many years you expect to own the place.
The climate behind Corinth's payback figure
2081 heating degree days pile up here every year, so Corinth has a mild winter by US standards; the cooling side runs to 3023 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: 10.9°F here (record low 9°F), which works out to a seasonal COP of 2.96 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Corinth — 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
Electricity use for heating alone comes out to about 1,780 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $704 a year. Corinth's gas rate of 19.42 per Mcf, applied to the 22 Mcf a year the furnace burns, puts its running cost near $1,054 a year, against 16.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 38.6 years; over 15 years the net position sits $1,748 ahead.
Electric resistance heat in Corinth, compared
Not every home in Corinth has gas service. Swap the comparison to resistance heat instead of gas, and Corinth's answer improves. Switching saves about $780 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 10.3 years.
Corinth against the rest of the country
Among 3206 cities, Corinth's winter puts it at rank 2393 for severity, while its size puts it at rank 1643 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
Next step for 24,450 people in Corinth
About 24,450 people live in Corinth, 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.

Where Corinth's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Corinth's 2.96 seasonal COP and payback figure. Corinth's 10.9°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.
