How cold Desert Hot Springs actually gets
Desert Hot Springs barely has a winter to speak of, 569 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 4961 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 37.9°F, and the coldest daily reading in the 2024 station record was 37°F. That puts the seasonal coefficient of performance at 3.33 for the recommended standard unit. Desert Hot Springs'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, Palm Springs International Airport, 9.6 miles from Desert Hot Springs.
The yearly running costs in Desert Hot Springs
Electricity use for heating alone comes out to about 433 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,531 a year. That compares with roughly 6 Mcf a year of gas at Desert Hot Springs's $22.01 per-Mcf rate, about $2,241 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 $7,657 ahead.
What would change Desert Hot Springs's answer
In Desert Hot Springs the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Desert Hot Springs: the heat pump is worth it within a decade if it costs less than $7,100 more than replacing the furnace and AC, and within 7 years if the gap is under $4,970.
The other scenario: no gas furnace to begin with
Gas isn't universal in Desert Hot Springs, many houses run on electric heat already. 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 $1,053 a year, which recovers the extra $7,500 spent going electric in roughly 7.1 years.
