Heat pump vs. gas furnace in Temple City, CA
In Temple City, a heat pump pays for itself within a reasonable window. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Lower bills claw that back: about $323 saved annually, for a payback of roughly 3.1 years. That's a real payback, built from Temple City's own climate and utility rates, not a national guess.
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 record low of 37.4°F on file. 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 (electricity here runs 32.83¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 34.1 years, for a 15-year net position $3,842 ahead.
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 7.5-year payback clears the $5,500 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.
