Is a heat pump worth it in Santa Barbara?

Santa Barbara is a place where a heat pump genuinely costs more to operate than the alternative. $1,000 is what Santa Barbara 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. Running costs here land $11 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Santa Barbara's numbers say wait.

Why Santa Barbara's climate drives this number

Santa Barbara has a mild winter by US standards — 2276 heating degree days a year against a 65°F base — and summers rarely ask much of an air conditioner, at 21 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 44.6°F, against a record low of 42.3°F. That puts the seasonal coefficient of performance at 3.53 for the recommended standard unit. A standard ducted system is enough here; Santa Barbara's design temperature doesn't justify the cold-climate premium. These numbers come from SANTA BARBARA, the closest NOAA station, 3.2 miles out.

Santa Barbara's running-cost comparison, in dollars

Electricity use for heating alone comes out to about 1,633 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $542 a year. That compares with roughly 24 Mcf a year of gas at Santa Barbara's 22.01 per-Mcf rate — about $531 a year — against a local electricity rate of 32.83¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $1,168 behind.

Electric resistance heat in Santa Barbara, compared

Not every home in Santa Barbara 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 $1,359 a year, which recovers the extra $5,500 spent going electric in roughly 4 years.

Santa Barbara against the rest of the country

Among 3206 cities, Santa Barbara's winter puts it at rank 2286 for severity, while its size puts it at rank 411 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.

About 87,291 people live in Santa Barbara, 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.
