Why San Bernardino's climate drives this number
Degree days tell the story here: San Bernardino racks up 1387 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1882 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 33.8°F, and the coldest daily reading in the 2024 station record was 33.1°F. That puts the seasonal coefficient of performance at 3.21 for the recommended standard unit. A standard ducted system is enough here; San Bernardino's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, Norton Aaf, 3.8 miles from San Bernardino.
The yearly running costs in San Bernardino
Electricity use for heating alone comes out to about 1,094 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $886 a year. That compares with roughly 14 Mcf a year of gas at San Bernardino's $22.01 per-Mcf rate, about $1,119 a year with the old AC included, against a local electricity rate of 32.83¢/kWh. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $490 ahead.
How sensitive San Bernardino's result is to prices
This result holds unless electricity climbs above 122.4¢/kWh (it is 32.83¢ now) or gas drops below $5.90 per Mcf (now $22.01); past either point, gas becomes the cheaper fuel in San Bernardino. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $233 a year saved, a difference under $1,631 pays back within 7 years here, and under $2,330 within 10.
Electric resistance heat in San Bernardino, compared
Gas isn't universal in San Bernardino, 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 $1,068 a year comes back this way, enough that the 7-year payback clears the $7,500 premium comfortably within the equipment's life.
San Bernardino against the rest of the country
Ranked against the other 3206 cities covered, San Bernardino comes in at 2737 for heating severity, 1 would be the coldest place in the dataset, and 107 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.
