Heat Pump Payback in Gallup, NM
Gallup, NM: the heat pump payback math
Gallup is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Gallup would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $153 a year here, so the extra spend stays unrecovered. That's Gallup's own climate and rates talking, not a hedge or a caveat.

Gallup's weather, in the numbers that matter
Gallup has a cold winter that leans hard on heating equipment, 5657 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 684 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 1°F, and the coldest daily reading in the 2024 station record was -11.9°F. That puts the seasonal coefficient of performance at 2.72 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Gallup sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Gallup Municipal Airport, 2.8 miles from Gallup.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 5,266 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $863 a year. The gas furnace it replaces burns roughly 59 Mcf a year at $9.83 per Mcf here, for a running cost near $710 a year including the old AC (electricity here runs 14.75¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $7,794 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Gallup's answer
For the verdict in Gallup to flip, electricity would need to drop to about 11.7¢/kWh from 14.75¢, or gas climb past $12.43 per Mcf from $9.83. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Gallup; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Gallup, compared
Not every home in Gallup has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. Switching saves about $1,381 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 7.2 years.
Gallup against the rest of the country
Gallup lands at position 327 out of 3206 cities on heating severity (coldest is 1), and 1892 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
Deciding what's next in Gallup, NM
Gallup, New Mexico is home to about 20,339 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 Gallup, nothing is lost by holding off until the current equipment genuinely fails.
