Lovington, NM: the heat pump payback math
Lovington technically pencils out, but only past the point the equipment would need replacing anyway. $3,500 is what Lovington would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $105 saved annually, for a payback of roughly 33.4 years. Lovington's own numbers say this pencils out only in theory, not in practice.
The climate behind Lovington's payback figure
Lovington has a mild winter by US standards — 2642 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2432 cooling degree days. 14°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 6.8°F on file. Worked through the model, that's a seasonal COP of 3.04 on the cold-climate unit fit for this climate. Lovington needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from LEA COUNTY REGIONAL AIRPORT, the closest NOAA station, 19.1 miles out.
Lovington's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,201 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $630 a year. That compares with roughly 28 Mcf a year of gas at Lovington's 9.83 per-Mcf rate — about $735 a year — against a local electricity rate of 14.75¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 128.7 years, leaving the 15-year total $1,926 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Lovington — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $821 a year comes back this way, enough that the 9.7-year payback clears the $8,000 premium comfortably within the equipment's life.
How Lovington compares nationally
Lovington lands at position 2071 out of 3206 cities on heating severity (coldest is 1), and 2862 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
