Will a heat pump pay off in Liberty Hill, TX?
In Liberty Hill, 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 $310 of lower running costs every year, landing the payback clock at roughly 11.3 years. Whether that's worth it in Liberty Hill depends on how many years you expect to own the place.
The climate behind Liberty Hill's payback figure
1387 heating degree days pile up here every year, so Liberty Hill barely has a winter to speak of; the cooling side runs to 2954 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 17.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 13.3°F on file. Worked through the model, that's a seasonal COP of 3.12 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Liberty Hill sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, AUSTIN 33 NW , 11 miles from Liberty Hill.
The month-to-month numbers for Liberty Hill
A 2000-square-foot house here would pull roughly 1,126 heating kilowatt-hours annually on top of cooling, totalling about $589 a year on electricity. That compares with roughly 14 Mcf a year of gas at Liberty Hill's 19.42 per-Mcf rate — about $899 a year — against a local electricity rate of 16.15¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 43.5 years, for a 15-year net position $1,154 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Liberty Hill — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $597 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 13.4 years.
How Liberty Hill compares nationally
Ranked against the other 3206 cities covered, Liberty Hill comes in at 2741 for heating severity — 1 would be the coldest place in the dataset — and 2810 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.

Where Liberty Hill's figure comes from
The methodology guide walks through exactly how Liberty Hill's 3.12 seasonal COP and the rest of this page's numbers get built. Liberty Hill's 17.4°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
