Heat Pump Payback in Loma Linda, CA
Will a heat pump pay off in Loma Linda, CA?
In Loma Linda, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. Lower bills claw that back: about $236 saved annually, for a payback of roughly 12.7 years. It's a genuine toss-up here, Loma Linda's numbers don't point clearly either way.

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 (coldest 2024 reading 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 International, 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 the current furnace-and-AC running cost near $1,205 a year, against 32.83¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $540 ahead.
How sensitive Loma Linda's result is to prices
Gas would only overtake the heat pump in Loma Linda if electricity rose past 89.3¢/kWh from 32.83¢, or gas fell under $8.09 per Mcf from $22.01. A useful quote test for Loma Linda: the heat pump is worth it within a decade if it costs less than $2,360 more than replacing the furnace and AC, and within 7 years if the gap is under $1,652.
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 $7,500 spent up front comes back in about 6.2 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.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Loma Linda's 3.21 seasonal COP and payback figure. Homes in Loma Linda without gas service should read the electric-resistance comparison instead, the numbers there differ from the gas case above.
