Will a heat pump pay off in Calexico, CA?
Calexico is a clear case: a heat pump beats what you have by a wide margin. $1,000 is what Calexico 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 $399 saved annually, for a payback of roughly 2.5 years. That verdict holds specifically for Calexico's own climate and rates, not a national average.
Calexico's weather, in the numbers that matter
Calexico barely has a winter to speak of — 944 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 2937 cooling degree days. Sizing runs off the design temperature, not the average day: 34°F here (record low 32°F), which works out to a seasonal COP of 3.21 for the standard class of unit this climate calls for. Calexico's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, IMPERIAL COUNTY AIRPORT, 11.4 miles from Calexico.
Calexico's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 745 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,067 a year. The gas furnace it replaces burns roughly 10 Mcf a year at 22.01 per Mcf here, for a running cost near $1,466 a year (electricity here runs 32.83¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 27.5 years, for a 15-year net position $4,991 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Calexico has gas service. Swap the comparison to resistance heat instead of gas, and Calexico's answer improves. The saving here runs about $968 a year, which recovers the extra $5,500 spent going electric in roughly 5.7 years.
