Heat Pump Payback in Campbell, CA
Is a heat pump worth it in Campbell?
In Campbell, the extra upfront cost technically comes back, just not before the equipment wears out. 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 $92 saved annually, for a payback of roughly 32.5 years. That's a technicality, not a recommendation, for anyone actually living in Campbell.

How cold Campbell actually gets
Campbell has a mild winter by US standards, 1672 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 922 cooling degree days. Sizing runs off the design temperature, not the average day: 36°F here (coldest 2024 reading 35.1°F), which works out to a seasonal COP of 3.27 for the standard class of unit this climate calls for. Campbell's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from N Y. Mineta Sn Jo International Apt, the closest NOAA station, 5.7 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 1,295 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $683 a year. Campbell'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 $776 a year, against 32.83¢ per kWh for electricity. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,614 behind.
How sensitive Campbell's result is to prices
Gas would only overtake the heat pump in Campbell if electricity rose past 43.3¢/kWh from 32.83¢, or gas fell under $16.70 per Mcf from $22.01. A useful quote test for Campbell: the heat pump is worth it within a decade if it costs less than $920 more than replacing the furnace and AC, and within 7 years if the gap is under $644.
Electric resistance heat in Campbell, compared
Gas isn't universal in Campbell, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Campbell's answer improves. Switching saves about $1,099 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 6.8 years.
Campbell against the rest of the country
Among 3206 cities, Campbell's winter puts it at rank 2602 for severity, while its size puts it at rank 959 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.
What to do with this number in Campbell
