Heat Pump Payback in Hanford, CA
Hanford, CA: the heat pump payback math
This one's marginal in Hanford: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Hanford's residents would see roughly $315 a year back in running costs, putting the payback around 9.5 years. It's a genuine toss-up here, Hanford's numbers don't point clearly either way.

How cold Hanford actually gets
Degree days tell the story here: Hanford racks up 2130 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2711 cooling degree days on the cooling side. 30.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 30°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.12 on the standard unit fit for this climate. Hanford's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Hanford Municipal Airport, the closest NOAA station, 1.6 miles out.
The yearly running costs in Hanford
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,729 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,326 a year. That compares with roughly 22 Mcf a year of gas at Hanford's $22.01 per-Mcf rate, about $1,642 a year with the old AC included, against a local electricity rate of 32.83¢/kWh. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,730 ahead.
What would change Hanford's answer
Gas would only overtake the heat pump in Hanford if electricity rose past 92.7¢/kWh from 32.83¢, or gas fell under $7.79 per Mcf from $22.01. A useful quote test for Hanford: the heat pump is worth it within a decade if it costs less than $3,150 more than replacing the furnace and AC, and within 7 years if the gap is under $2,205.
Electric resistance heat in Hanford, compared
Plenty of homes in Hanford 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. Switching saves about $1,598 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 4.7 years.
Where Hanford ranks in this dataset
Hanford lands at position 2370 out of 3206 cities on heating severity (coldest is 1), and 662 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.
Next step if you live in Hanford
Hanford, California is home to about 60,594 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 Hanford, 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 Hanford's 3.12 seasonal COP and payback figure. Homes in Hanford without gas service should read the electric-resistance comparison instead, the numbers there differ from the gas case above.
