Heat Pump Payback in Dallas, TX
Heat pump vs. gas furnace in Dallas, TX
Dallas 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. Lower bills claw that back: about $360 saved annually, for a payback of roughly 15.3 years. Dallas's own numbers say this pencils out only in theory, not in practice.

Why Dallas's climate drives this number
Degree days tell the story here: Dallas racks up 1633 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3396 cooling degree days on the cooling side. 18°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 10°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 18°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 Dallas.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 1,321 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $681 a year. The gas furnace it replaces burns roughly 17 Mcf a year at $19.42 per Mcf here, for a running cost near $1,041 a year including the old AC (electricity here runs 16.15¢/kWh). If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $99 behind.
How sensitive Dallas's result is to prices
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Dallas at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $360 a year saved, a difference under $2,520 pays back within 7 years here, and under $3,600 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Dallas, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Dallas's answer improves. Switching saves about $698 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 14.3 years.
Dallas against the rest of the country
Ranked against the other 3206 cities covered, Dallas comes in at 2626 for heating severity, 1 would be the coldest place in the dataset, and 9 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.

About 1,326,087 people live in Dallas, 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 Dallas's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Dallas's 3.13 seasonal COP and payback figure. Dallas's 18°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
