Heat Pump Payback in Santa Fe, TX
Heat pump vs. gas furnace in Santa Fe, TX
In Santa Fe, 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 $3,000 more up front here. Lower bills claw that back: about $318 saved annually, for a payback of roughly 9.4 years. Whether that's worth it in Santa Fe depends on how many years you expect to own the place.

The climate behind Santa Fe's payback figure
Santa Fe barely has a winter to speak of, 795 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 3633 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 32°F, and the coldest daily reading in the 2024 station record was 19.9°F. That puts the seasonal coefficient of performance at 3.15 for the recommended standard unit. A standard ducted system is enough here; Santa Fe's design temperature doesn't justify the cold-climate premium. These numbers come from Clover Field Airport, the closest NOAA station, 12.4 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 639 kWh a year to keep it warm, plus cooling, for a combined electric bill near $603 a year. That compares with roughly 8 Mcf a year of gas at Santa Fe's $19.42 per-Mcf rate, about $921 a year with the old AC included, against a local electricity rate of 16.15¢/kWh. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,766 ahead.
What would change Santa Fe's answer
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 Santa Fe at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $318 a year saved, a difference under $2,226 pays back within 7 years here, and under $3,180 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in Santa Fe heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Santa Fe's answer improves. Even against resistance heat, the running-cost gap here isn't enough to clear the $7,500 incremental cost within the equipment's 15-year life.
Where Santa Fe ranks in this dataset
Among 3206 cities, Santa Fe's winter puts it at rank 2975 for severity, while its size puts it at rank 2635 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.

More on how this number was built
Every constant behind this page, the 3.15 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Not every home in Santa Fe has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
