Heat Pump Payback in Temple City, CA
Heat pump vs. gas furnace in Temple City, CA
In Temple City, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,000. Lower bills claw that back: about $323 saved annually, for a payback of roughly 9.3 years. Whether that's worth it in Temple City depends on how many years you expect to own the place.

The climate behind Temple City's payback figure
Temple City 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. 39.2°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 37.4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.37 on the standard unit fit for this climate. A standard ducted system is enough here; Temple City's design temperature doesn't justify the cold-climate premium. These numbers come from El Monte Airport, the closest NOAA station, 1.9 miles out.
Temple City's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 515 kWh a year to keep it warm, plus cooling, for a combined electric bill near $813 a year. 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). 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 $1,842 ahead.
What would change Temple City's answer
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 Temple City 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.
The other scenario: no gas furnace to begin with
Not every home in Temple City has gas service. Swap the comparison to resistance heat instead of gas, and Temple City's answer improves. About $736 a year comes back this way, enough that the 10.2-year payback clears the $7,500 premium comfortably within the equipment's life.
How Temple City compares nationally
Among 3206 cities, Temple City's winter puts it at rank 3008 for severity, while its size puts it at rank 1176 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.
