Heat Pump Payback in Sierra Madre, CA
Heat pump vs. gas furnace in Sierra Madre, CA
Sierra Madre sits right on the fence, how long you'll own the house decides this one. $3,000 is what Sierra Madre would pay extra to go electric rather than replace the furnace and AC with the same again. Sierra Madre's residents would see roughly $323 a year back in running costs, putting the payback around 9.3 years. It's a genuine toss-up here, Sierra Madre's numbers don't point clearly either way.

How cold Sierra Madre actually gets
Degree days tell the story here: Sierra Madre racks up 686 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2300 cooling degree days on the cooling side. 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. Sierra Madre'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, El Monte Airport, 6 miles from Sierra Madre.
The yearly running costs in Sierra Madre
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). 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.
The break-even point in Sierra Madre
In Sierra Madre 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 Sierra Madre: the heat pump is worth it within a decade if it costs less than $3,230 more than replacing the furnace and AC, and within 7 years if the gap is under $2,261.
If your home heats with electric baseboard instead of gas
Plenty of homes in Sierra Madre heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. 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.
Where Sierra Madre ranks in this dataset
Sierra Madre lands at position 3014 out of 3206 cities on heating severity (coldest is 1), and 3031 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.

More on how this number was built
The methodology guide walks through exactly how Sierra Madre's 3.37 seasonal COP and the rest of this page's numbers get built. Homes in Sierra Madre without gas service should read the electric-resistance comparison instead, the numbers there differ from the gas case above.
