Should Abilene switch to a heat pump?
In Abilene, the math is close enough that it comes down to how long you plan to stay. $3,500 is what Abilene 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. That premium is recovered through $348 of lower running costs every year, landing the payback clock at roughly 10 years. It's a genuine toss-up here — Abilene's numbers don't point clearly either way.
Abilene's weather, in the numbers that matter
Degree days tell the story here: Abilene racks up 1899 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3106 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 12.9°F here (record low 8.1°F), which works out to a seasonal COP of 3.01 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Abilene — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, ABILENE REGIONAL AIRPORT, 4.4 miles from Abilene.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 1,598 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $686 a year. Abilene's gas rate of 19.42 per Mcf, applied to the 20 Mcf a year the furnace burns, puts its running cost near $1,034 a year, against 16.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 38.7 years; over 15 years the net position sits $1,727 ahead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Abilene — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $741 a year, which recovers the extra $8,000 spent going electric in roughly 10.8 years.
Where Abilene ranks in this dataset
Among 3206 cities, Abilene's winter puts it at rank 2484 for severity, while its size puts it at rank 223 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 130,501 people in Abilene
Abilene, Texas is home to about 130,501 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Abilene, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Abilene's 3.01 seasonal COP and payback figure. Abilene's 12.9°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.
