HeatPumpPayback

Will a heat pump pay off in Claremont, CA?

In Claremont, a heat pump pays for itself within a reasonable window. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $208 of lower running costs every year, landing the payback clock at roughly 4.8 years. That's a real payback, built from Claremont's own climate and utility rates, not a national guess.

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 record low of 39.2°F on file. 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 month-to-month numbers for 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 — against a local electricity rate of 32.83¢/kWh. Buy it outright, not incrementally, and payback stretches to 52.9 years; over 15 years the net position sits $2,117 ahead.

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 4.9-year payback clears the $5,500 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.
