Heat Pump Payback in Claremont, CA
Will a heat pump pay off in Claremont, CA?
In Claremont, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. That premium is recovered through $208 of lower running costs every year, landing the payback clock at roughly 14.4 years. Whether that's worth it in Claremont depends on how many years you expect to own the place.

Why Claremont's climate drives this number
1518 heating degree days pile up here every year, so Claremont has a mild winter by US standards; the cooling side runs to 1572 cooling degree days, where summers are hot enough that cooling matters as much as heating. 41°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 39.2°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.42 on the standard unit fit for this climate. A standard ducted system is enough here; Claremont's design temperature doesn't justify the cold-climate premium. Source: NOAA station Cable, 1.7 miles from Claremont, the closest one on record.
The yearly running costs in Claremont
Electricity use for heating alone comes out to about 1,124 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $809 a year. That compares with roughly 16 Mcf a year of gas at Claremont's $22.01 per-Mcf rate, about $1,017 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 $117 ahead.
The break-even point in Claremont
This result holds unless electricity climbs above 81.5¢/kWh (it is 32.83¢ now) or gas drops below $8.87 per Mcf (now $22.01); past either point, gas becomes the cheaper fuel in Claremont. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $208 a year saved, a difference under $1,456 pays back within 7 years here, and under $2,080 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in Claremont heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $1,122 a year comes back this way, enough that the 6.7-year payback clears the $7,500 premium comfortably within the equipment's life.
How Claremont compares nationally
Claremont lands at position 2681 out of 3206 cities on heating severity (coldest is 1), and 1141 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
