Heat pump vs. gas furnace in Gainesville, TX
Gainesville sits right on the fence — how long you'll own the house decides this one. $3,500 is what Gainesville 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 $348 saved annually, for a payback of roughly 10.1 years. Whether that's worth it in Gainesville depends on how many years you expect to own the place.
Why Gainesville's climate drives this number
Gainesville has a mild winter by US standards — 2068 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 2893 cooling degree days. Sizing runs off the design temperature, not the average day: 14.4°F here (record low 8.6°F), which works out to a seasonal COP of 3.05 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Gainesville sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,717 heating kilowatt-hours annually on top of cooling, totalling about $676 a year on electricity. That compares with roughly 22 Mcf a year of gas at Gainesville's 19.42 per-Mcf rate — about $1,024 a year — against a local electricity rate of 16.15¢/kWh. Buy it outright, not incrementally, and payback stretches to 38.8 years; over 15 years the net position sits $1,722 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Gainesville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Gainesville's answer improves. Switching saves about $776 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.
Where Gainesville ranks in this dataset
Ranked against the other 3206 cities covered, Gainesville comes in at 2408 for heating severity — 1 would be the coldest place in the dataset — and 2065 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.
