HeatPumpPayback

Heat pump vs. gas furnace in San Bernardino, CA

San Bernardino clears a genuine payback here, inside a reasonable stretch of years. $1,000 is what San Bernardino 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. San Bernardino's residents would see roughly $233 a year back in running costs, putting the payback around 4.3 years. That's a real payback, built from San Bernardino's own climate and utility rates, not a national guess.

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, against a record low of 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 month-to-month numbers for 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 — against a local electricity rate of 32.83¢/kWh. Buy it outright, not incrementally, and payback stretches to 47.3 years; over 15 years the net position sits $2,490 ahead.

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 5.2-year payback clears the $5,500 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.

What to do with this number in San Bernardino

About 224,775 people live in San Bernardino, California, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, it's worth getting quotes before your current system fails, not after.

Ask a local HVAC contractor for a quote before committing either way.
