Heat Pump Payback in Long Beach, CA
Long Beach, CA: the heat pump payback math
In Long Beach, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $3,000 more up front here. Long Beach's residents would see roughly $114 a year back in running costs, putting the payback around 26.3 years. That's a technicality, not a recommendation, for anyone actually living in Long Beach.

How cold Long Beach actually gets
Degree days tell the story here: Long Beach racks up 1041 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 884 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 41°F, and the coldest daily reading in the 2024 station record was 39.9°F. That puts the seasonal coefficient of performance at 3.42 for the recommended standard unit. Long Beach's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine. These numbers come from Long Beach / Daugherty Field, the closest NOAA station, 2.5 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 771 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $500 a year. The gas furnace it replaces burns roughly 11 Mcf a year at $22.01 per Mcf here, for a running cost near $615 a year including the old AC (electricity here runs 32.83¢/kWh). If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $1,286 behind.
How sensitive Long Beach's result is to prices
Gas would only overtake the heat pump in Long Beach if electricity rose past 63.0¢/kWh from 32.83¢, or gas fell under $11.47 per Mcf from $22.01. A useful quote test for Long Beach: the heat pump is worth it within a decade if it costs less than $1,140 more than replacing the furnace and AC, and within 7 years if the gap is under $798.
The other scenario: no gas furnace to begin with
Plenty of homes in Long Beach heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Long Beach's answer improves. The saving here runs about $741 a year, which recovers the extra $7,500 spent going electric in roughly 10.1 years.
How Long Beach compares nationally
Among 3206 cities, Long Beach's winter puts it at rank 2882 for severity, while its size puts it at rank 44 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 Long Beach
Long Beach, California is home to about 450,901 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 Long Beach, nothing is lost by holding off until the current equipment genuinely fails.

The methodology guide walks through exactly how Long Beach's 3.42 seasonal COP and the rest of this page's numbers get built. Long Beach technically clears a payback on paper, just past the equipment's own working life, the no-payback guide explains why that distinction matters.
