Will a heat pump pay off in Anaheim, CA?
In Anaheim, 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 $1,000 more up front here (already netting out a $2,000 tax credit). Anaheim's residents would see roughly $61 a year back in running costs, putting the payback around 16.4 years. Anaheim's own numbers say this pencils out only in theory, not in practice.
The climate behind Anaheim's payback figure
Degree days tell the story here: Anaheim racks up 1830 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1020 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 27°F, against a record low of 26.1°F. That puts the seasonal coefficient of performance at 3 for the recommended standard unit. A standard ducted system is enough here; Anaheim's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, CORONA MUNICIPAL AIRPORT, 9.5 miles from Anaheim.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,545 heating kilowatt-hours annually on top of cooling, totalling about $793 a year on electricity. That compares with roughly 19 Mcf a year of gas at Anaheim's 22.01 per-Mcf rate — about $853 a year — against a local electricity rate of 32.83¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 180.7 years, for a 15-year net position $87 behind.
Electric resistance heat in Anaheim, compared
Not every home in Anaheim has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $1,163 a year, which recovers the extra $5,500 spent going electric in roughly 4.7 years.
How Anaheim compares nationally
Among 3206 cities, Anaheim's winter puts it at rank 2519 for severity, while its size puts it at rank 57 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.
Deciding what's next in Anaheim, CA
About 344,561 people live in Anaheim, California, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
