Should Redondo Beach switch to a heat pump?
This one's marginal in Redondo Beach: it only clears if you stay long enough. $1,000 is what Redondo Beach would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $95 saved annually, for a payback of roughly 10.5 years. Whether that's worth it in Redondo Beach depends on how many years you expect to own the place.
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 record low of 35.6°F on file. 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 month-to-month numbers for 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 (electricity here runs 32.83¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 115.6 years, for a 15-year net position $427 ahead.
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 $5,500 spent going electric in roughly 7.2 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.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Redondo Beach's 3.31 seasonal COP and payback figure. Not every home in Redondo Beach has gas; the guide comparing a heat pump against electric baseboard covers that case separately.
