Heat Pump Payback in Fillmore, CA
Is a heat pump worth it in Fillmore?
The payback math works in Fillmore on paper, past the equipment's own working life. $3,000 is what Fillmore would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $41 of lower running costs every year, landing the payback clock at roughly 73 years. That's a technicality, not a recommendation, for anyone actually living in Fillmore.

How cold Fillmore actually gets
1730 heating degree days pile up here every year, so Fillmore has a mild winter by US standards; the cooling side runs to 655 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 33.1°F here (coldest 2024 reading 33.1°F), which works out to a seasonal COP of 3.19 for the standard class of unit this climate calls for. Fillmore's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. Climate figures trace to the nearest NOAA station, Camarillo Airport, 15.7 miles from Fillmore.
Fillmore's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,373 kWh a year to keep it warm, plus cooling, for a combined electric bill near $634 a year. Fillmore's gas rate of $22.01 per Mcf, applied to the 18 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $675 a year, against 32.83¢ per kWh for electricity. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $2,384 behind.
How sensitive Fillmore's result is to prices
Gas would only overtake the heat pump in Fillmore if electricity rose past 36.6¢/kWh from 32.83¢, or gas fell under $19.73 per Mcf from $22.01. A useful quote test for Fillmore: the heat pump is worth it within a decade if it costs less than $410 more than replacing the furnace and AC, and within 7 years if the gap is under $287.
Electric resistance heat in Fillmore, compared
Gas isn't universal in Fillmore, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,083 a year comes back this way, enough that the 6.9-year payback clears the $7,500 premium comfortably within the equipment's life.
Fillmore against the rest of the country
Ranked against the other 3206 cities covered, Fillmore comes in at 2572 for heating severity, 1 would be the coldest place in the dataset, and 2175 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.
