Lynwood, CA: the heat pump payback math
This one's marginal in Lynwood: it only clears if you stay long enough. $1,000 is what Lynwood 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 — Lynwood's numbers don't point clearly either way.
How cold Lynwood actually gets
1268 heating degree days pile up here every year, so Lynwood barely has a winter to speak of; the cooling side runs to 622 cooling degree days, where summers add a moderate cooling load. 44.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 44.1°F on file. Worked through the model, that's a seasonal COP of 3.51 on the standard unit fit for this climate. Lynwood's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, NRTHORP FLD/HATHRN MUNI AP, 7.6 miles from Lynwood.
The month-to-month numbers for Lynwood
Electricity use for heating alone comes out to about 915 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $474 a year. That compares with roughly 13 Mcf a year of gas at Lynwood's 22.01 per-Mcf rate — about $555 a year — against a local electricity rate of 32.83¢/kWh. 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 Lynwood 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.
How Lynwood compares nationally
Among 3206 cities, Lynwood's winter puts it at rank 2773 for severity, while its size puts it at rank 620 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
What to do with this number in Lynwood
Lynwood, California is home to about 63,596 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 Lynwood, nothing is lost by holding off until the current equipment genuinely fails.
