Heat Pump Payback in Saratoga, CA
Heat pump vs. gas furnace in Saratoga, CA
In Saratoga, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Saratoga's residents would see roughly $92 a year back in running costs, putting the payback around 32.5 years. That's a technicality, not a recommendation, for anyone actually living in Saratoga.

How cold Saratoga actually gets
Degree days tell the story here: Saratoga racks up 1672 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 922 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 36°F, and the coldest daily reading in the 2024 station record was 35.1°F. That puts the seasonal coefficient of performance at 3.27 for the recommended standard unit. Saratoga's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,295 kWh a year to keep it warm, plus cooling, for a combined electric bill near $683 a year. That compares with roughly 17 Mcf a year of gas at Saratoga's $22.01 per-Mcf rate, about $776 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 $1,614 behind.
What would change Saratoga's answer
Gas would only overtake the heat pump in Saratoga if electricity rose past 43.3¢/kWh from 32.83¢, or gas fell under $16.70 per Mcf from $22.01. A useful quote test for Saratoga: the heat pump is worth it within a decade if it costs less than $920 more than replacing the furnace and AC, and within 7 years if the gap is under $644.
The other scenario: no gas furnace to begin with
Not every home in Saratoga has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,099 a year, which recovers the extra $7,500 spent going electric in roughly 6.8 years.
Where Saratoga ranks in this dataset

Where Saratoga's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Saratoga's 3.27 seasonal COP and payback figure. Saratoga technically clears a payback on paper, just past the equipment's own working life, the no-payback guide explains why that distinction matters.
