Heat Pump Payback in Cudahy, CA
Will a heat pump pay off in Cudahy, CA?
In Cudahy, the extra upfront cost technically comes back, just not before the equipment wears out. $3,000 is what Cudahy would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $81 saved annually, for a payback of roughly 37.1 years. That's a technicality, not a recommendation, for anyone actually living in Cudahy.

How cold Cudahy actually gets
Degree days tell the story here: Cudahy racks up 1268 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 622 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 44.1°F here (coldest 2024 reading 44.1°F), which works out to a seasonal COP of 3.51 for the standard class of unit this climate calls for. Cudahy's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Nrthorp Fld/Hathrn Municipal AP, the closest NOAA station, 9.1 miles out.
The yearly running costs in Cudahy
A 2000-square-foot house here would pull roughly 915 heating kilowatt-hours annually on top of cooling, totalling about $474 a year on electricity. Cudahy's gas rate of $22.01 per Mcf, applied to the 13 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $555 a year, against 32.83¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,787 behind.
What would change Cudahy's answer
Gas would only overtake the heat pump in Cudahy if electricity rose past 45.5¢/kWh from 32.83¢, or gas fell under $15.88 per Mcf from $22.01. A useful quote test for Cudahy: the heat pump is worth it within a decade if it costs less than $810 more than replacing the furnace and AC, and within 7 years if the gap is under $567.
The other scenario: no gas furnace to begin with
Gas isn't universal in Cudahy, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $844 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $7,500 spent up front comes back in about 8.9 years.
How Cudahy compares nationally
Ranked against the other 3206 cities covered, Cudahy comes in at 2779 for heating severity, 1 would be the coldest place in the dataset, and 1804 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.
