Will a heat pump pay off in Cudahy, CA?
In Cudahy, the math is close enough that it comes down to how long you plan to stay. $1,000 is what Cudahy 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 $81 saved annually, for a payback of roughly 12.4 years. It's a genuine toss-up here — Cudahy's numbers don't point clearly either way.
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 (record low 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 MUNI AP, the closest NOAA station, 9.1 miles out.
The month-to-month numbers for 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 its running cost near $555 a year, against 32.83¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 136 years; over 15 years the net position sits $213 ahead.
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 $5,500 spent up front comes back in about 6.5 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.
