Heat Pump Payback in Garland, TX
Will a heat pump pay off in Garland, TX?
Garland technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $334 of lower running costs every year, landing the payback clock at roughly 16.5 years. Garland's own numbers say this pencils out only in theory, not in practice.

The climate behind Garland's payback figure
Degree days tell the story here: Garland racks up 1853 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2871 cooling degree days on the cooling side. 15.8°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 9.5°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.08 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 15.8°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Garland. These numbers come from Ralph M Hall Rockwall Municip, the closest NOAA station, 11.4 miles out.
The yearly running costs in Garland
A 2000-square-foot house here would pull roughly 1,523 heating kilowatt-hours annually on top of cooling, totalling about $641 a year on electricity. Garland's gas rate of $19.42 per Mcf, applied to the 19 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $976 a year, against 16.15¢ per kWh for electricity. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $485 behind.
The break-even point in Garland
This result holds unless electricity climbs above 149.6¢/kWh (it is 16.15¢ now) or gas drops below $2.10 per Mcf (now $19.42); past either point, gas becomes the cheaper fuel in Garland. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $334 a year saved, a difference under $2,338 pays back within 7 years here, and under $3,340 within 10.
Electric resistance heat in Garland, compared
Gas isn't universal in Garland, 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 $717 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 13.9 years.
How Garland compares nationally
Ranked against the other 3206 cities covered, Garland comes in at 2505 for heating severity, 1 would be the coldest place in the dataset, and 93 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.
