How cold Palm Desert actually gets
569 heating degree days pile up here every year, so Palm Desert barely has a winter to speak of; the cooling side runs to 4961 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 37.9°F here (coldest 2024 reading 37°F), which works out to a seasonal COP of 3.33 for the standard class of unit this climate calls for. Palm Desert'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, 9.9 miles from Palm Desert.
What it actually costs to run, year to year
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. Palm Desert's gas rate of $22.01 per Mcf, applied to the 6 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $2,241 a year, against 32.83¢ per kWh for electricity. 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 $7,657 ahead.
What would change Palm Desert's answer
In Palm Desert 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 Palm Desert: 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.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Palm Desert, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,053 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 7.1 years.
Palm Desert against the rest of the country
Palm Desert lands at position 3037 out of 3206 cities on heating severity (coldest is 1), and 768 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 Palm Desert
Palm Desert, California is home to about 53,147 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.

Where Palm Desert's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Palm Desert's 3.33 seasonal COP and payback figure. Homes in Palm Desert without gas service should read the electric-resistance comparison instead, the numbers there differ from the gas case above.
