How cold Inglewood actually gets
Inglewood 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. 44.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 44.1°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.51 on the standard unit fit for this climate. Inglewood'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, 2.4 miles out.
What it actually costs to run, year to year
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 Inglewood's $22.01 per-Mcf rate, about $555 a year with the old AC included, against a local electricity rate of 32.83¢/kWh. 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.
How sensitive Inglewood's result is to prices
Gas would only overtake the heat pump in Inglewood 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 Inglewood: 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 Inglewood, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Inglewood's answer improves. About $844 a year comes back this way, enough that the 8.9-year payback clears the $7,500 premium comfortably within the equipment's life.
