Heat Pump Payback in Los Banos, CA
Is a heat pump worth it in Los Banos?
Los Banos technically pencils out, but only past the point the equipment would need replacing anyway. $3,000 is what Los Banos would pay extra to go electric rather than replace the furnace and AC with the same again. Los Banos's residents would see roughly $105 a year back in running costs, putting the payback around 28.7 years. That's a technicality, not a recommendation, for anyone actually living in Los Banos.

Los Banos's weather, in the numbers that matter
Degree days tell the story here: Los Banos racks up 2551 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1478 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 28.6°F, and the coldest daily reading in the 2024 station record was 26.6°F. That puts the seasonal coefficient of performance at 3.05 for the recommended standard unit. Los Banos's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Merced 23 Wsw, the closest NOAA station, 12.3 miles out.
Los Banos's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 2,118 heating kilowatt-hours annually on top of cooling, totalling about $1,109 a year on electricity. Los Banos's gas rate of $22.01 per Mcf, applied to the 27 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,214 a year, against 32.83¢ per kWh for electricity. 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 $1,431 behind.
What would change Los Banos's answer
Gas would only overtake the heat pump in Los Banos if electricity rose past 40.0¢/kWh from 32.83¢, or gas fell under $18.07 per Mcf from $22.01. A useful quote test for Los Banos: the heat pump is worth it within a decade if it costs less than $1,050 more than replacing the furnace and AC, and within 7 years if the gap is under $735.
The other scenario: no gas furnace to begin with
Not every home in Los Banos has gas service. Swap the comparison to resistance heat instead of gas, and Los Banos's answer improves. The saving here runs about $1,640 a year, which recovers the extra $7,500 spent going electric in roughly 4.6 years.
How Los Banos compares nationally
Los Banos lands at position 2121 out of 3206 cities on heating severity (coldest is 1), and 843 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Los Banos's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Los Banos's 3.05 seasonal COP and payback figure. Los Banos technically clears a payback on paper, just past the equipment's own working life, the no-payback guide explains why that distinction matters.
