Heat Pump Payback in El Monte, CA
Heat pump vs. gas furnace in El Monte, CA
This one's marginal in El Monte: it only clears if you stay long enough. $3,000 is what El Monte would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $323 of lower running costs every year, landing the payback clock at roughly 9.3 years. Whether that's worth it in El Monte depends on how many years you expect to own the place.

The climate behind El Monte's payback figure
El Monte barely has a winter to speak of, 686 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2300 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 39.2°F, and the coldest daily reading in the 2024 station record was 37.4°F. That puts the seasonal coefficient of performance at 3.37 for the recommended standard unit. A standard ducted system is enough here; El Monte's design temperature doesn't justify the cold-climate premium. These numbers come from El Monte Airport, the closest NOAA station, 0.6 miles out.
El Monte's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 515 heating kilowatt-hours annually on top of cooling, totalling about $813 a year on electricity. The gas furnace it replaces burns roughly 7 Mcf a year at $22.01 per Mcf here, for a running cost near $1,136 a year including the old AC (electricity here runs 32.83¢/kWh). If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,842 ahead.
How sensitive El Monte's result is to prices
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in El Monte at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $323 a year saved, a difference under $2,261 pays back within 7 years here, and under $3,230 within 10.
If your home heats with electric baseboard instead of gas
Not every home in El Monte 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 $736 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 10.2 years.
How El Monte compares nationally
El Monte lands at position 2997 out of 3206 cities on heating severity (coldest is 1), and 314 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.

About 104,639 people live in El Monte, California, and every number on this page is what a contractor would actually work from when quoting a system here, the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
