Brawley, CA: the heat pump payback math
The math in Brawley isn't close — a heat pump wins outright. $1,000 is what Brawley 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 Brawley's own climate and rates, not a national average.
How cold Brawley actually gets
Degree days tell the story here: Brawley racks up 944 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2937 cooling degree days on the cooling side. 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. Brawley's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from IMPERIAL COUNTY AIRPORT, the closest NOAA station, 10.4 miles out.
Brawley's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 745 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,067 a year. Brawley's gas rate of 22.01 per Mcf, applied to the 10 Mcf a year the furnace burns, puts its running cost near $1,466 a year, against 32.83¢ per kWh for electricity. 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
Plenty of homes in Brawley heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $968 a year comes back this way, enough that the 5.7-year payback clears the $5,500 premium comfortably within the equipment's life.
How Brawley compares nationally
Ranked against the other 3206 cities covered, Brawley comes in at 2929 for heating severity — 1 would be the coldest place in the dataset — and 1417 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.
