Heat Pump Payback in Redondo Beach, CA
Should Redondo Beach switch to a heat pump?
The payback math works in Redondo Beach on paper, past the equipment's own working life. $3,000 is what Redondo Beach would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $95 saved annually, for a payback of roughly 31.5 years. Redondo Beach's own numbers say this pencils out only in theory, not in practice.

Why Redondo Beach's climate drives this number
1112 heating degree days pile up here every year, so Redondo Beach barely has a winter to speak of; the cooling side runs to 821 cooling degree days, where summers add a moderate cooling load. 37.4°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 35.6°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.31 on the standard unit fit for this climate. A standard ducted system is enough here; Redondo Beach's design temperature doesn't justify the cold-climate premium.

The yearly running costs in Redondo Beach
Electricity use for heating alone comes out to about 851 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $509 a year. The gas furnace it replaces burns roughly 12 Mcf a year at $22.01 per Mcf here, for a running cost near $604 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 $1,573 behind.
What would change Redondo Beach's answer
This result holds unless electricity climbs above 52.4¢/kWh (it is 32.83¢ now) or gas drops below $13.80 per Mcf (now $22.01); past either point, gas becomes the cheaper fuel in Redondo Beach. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $95 a year saved, a difference under $665 pays back within 7 years here, and under $950 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Redondo Beach, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $765 a year, which recovers the extra $7,500 spent going electric in roughly 9.8 years.
Where Redondo Beach ranks in this dataset
Ranked against the other 3206 cities covered, Redondo Beach comes in at 2848 for heating severity, 1 would be the coldest place in the dataset, and 574 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
