La Quinta's weather, in the numbers that matter
1049 heating degree days pile up here every year, so La Quinta barely has a winter to speak of; the cooling side runs to 4551 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 28°F, and the coldest daily reading in the 2024 station record was 26.1°F. That puts the seasonal coefficient of performance at 3.03 for the recommended standard unit. La Quinta's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Desert Resorts Regional Airport, the closest NOAA station, 6.7 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 877 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,562 a year. The gas furnace it replaces burns roughly 11 Mcf a year at $22.01 per Mcf here, for a running cost near $2,177 a year including the old AC (electricity here runs 32.83¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $6,226 ahead.
The break-even point in La Quinta
In La Quinta 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 La Quinta: the heat pump is worth it within a decade if it costs less than $6,150 more than replacing the furnace and AC, and within 7 years if the gap is under $4,305.
Electric resistance heat in La Quinta, compared
Not every home in La Quinta 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. Switching saves about $1,247 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 6 years.
How La Quinta compares nationally
Among 3206 cities, La Quinta's winter puts it at rank 2881 for severity, while its size puts it at rank 1035 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
