Is a heat pump worth it in Compton?
Compton sits right on the fence — how long you'll own the house decides this one. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $81 saved annually, for a payback of roughly 12.4 years. It's a genuine toss-up here — Compton's numbers don't point clearly either way.
Compton's weather, in the numbers that matter
Compton barely has a winter to speak of — 1268 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 622 cooling degree days. 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. Compton'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, 6.4 miles out.
The month-to-month numbers for Compton
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. Compton'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.
If your home heats with electric baseboard instead of gas
Not every home in Compton has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $844 a year, which recovers the extra $5,500 spent going electric in roughly 6.5 years.
Where Compton ranks in this dataset
Ranked against the other 3206 cities covered, Compton comes in at 2770 for heating severity — 1 would be the coldest place in the dataset — and 386 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.
Deciding what's next in Compton, CA
Compton, California is home to about 91,129 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Compton, nothing is lost by holding off until the current equipment genuinely fails.
