Heat pump vs. gas furnace in Clovis, CA
The math in Clovis isn't close — a heat pump wins outright. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. That premium is recovered through $357 of lower running costs every year, landing the payback clock at roughly 2.8 years. That verdict holds specifically for Clovis's own climate and rates, not a national average.
Clovis's weather, in the numbers that matter
1958 heating degree days pile up here every year, so Clovis has a mild winter by US standards; the cooling side runs to 2853 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 34°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 33.1°F on file. Worked through the model, that's a seasonal COP of 3.21 on the standard unit fit for this climate. Clovis'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, FRESNO YOSEMITE INTERNATIONAL, 3.9 miles from Clovis.
Clovis's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,545 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,306 a year. That compares with roughly 20 Mcf a year of gas at Clovis's 22.01 per-Mcf rate — about $1,663 a year — against a local electricity rate of 32.83¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 30.8 years, leaving the 15-year total $4,356 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Clovis — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,536 a year, which recovers the extra $5,500 spent going electric in roughly 3.6 years.
Where Clovis ranks in this dataset
Ranked against the other 3206 cities covered, Clovis comes in at 2444 for heating severity — 1 would be the coldest place in the dataset — and 227 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 127,993 people in Clovis
Clovis, California is home to about 127,993 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. Given the math above, Clovis is a place worth lining up quotes ahead of a breakdown, not waiting for one.
