Will a heat pump pay off in Loma Linda, CA?
In Loma Linda, a heat pump pays for itself within a reasonable window. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Lower bills claw that back: about $236 saved annually, for a payback of roughly 4.2 years. The window here is reasonable, and it's specific to what Loma Linda actually pays for power and gas.
Loma Linda's weather, in the numbers that matter
Degree days tell the story here: Loma Linda racks up 1628 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1954 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 33.8°F here (record low 33.1°F), which works out to a seasonal COP of 3.21 for the standard class of unit this climate calls for. Loma Linda's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from SAN BERNARDINO INTL, the closest NOAA station, 3.6 miles out.
Loma Linda's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 1,284 heating kilowatt-hours annually on top of cooling, totalling about $969 a year on electricity. Loma Linda's gas rate of 22.01 per Mcf, applied to the 17 Mcf a year the furnace burns, puts its running cost near $1,205 a year, against 32.83¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 46.6 years, leaving the 15-year total $2,540 ahead.
The other scenario: no gas furnace to begin with
Not every home in Loma Linda has gas service. Swap the comparison to resistance heat instead of gas, and Loma Linda's answer improves. Switching saves about $1,216 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 4.5 years.
Where Loma Linda ranks in this dataset
Among 3206 cities, Loma Linda's winter puts it at rank 2636 for severity, while its size puts it at rank 1593 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.
