Is a heat pump worth it in Fillmore?
The payback math works in Fillmore on paper, past the equipment's own working life. $1,000 is what Fillmore 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. That premium is recovered through $41 of lower running costs every year, landing the payback clock at roughly 24.3 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 (record low 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 its running cost near $675 a year, against 32.83¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 267.8 years, leaving the 15-year total $384 behind.
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 5.1-year payback clears the $5,500 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.
Next step for 17,216 people in Fillmore
Fillmore, California is home to about 17,216 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Fillmore, nothing is lost by holding off until the current equipment genuinely fails.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Fillmore's 3.19 seasonal COP and payback figure. Fillmore technically clears a payback on paper, just past the equipment's own working life — the no-payback guide explains why that distinction matters.
