Heat pump vs. gas furnace in Laguna Beach, CA
In Laguna Beach, the math is close enough that it comes down to how long you plan to stay. $1,000 is what Laguna Beach 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. Laguna Beach's residents would see roughly $106 a year back in running costs, putting the payback around 9.4 years. It's a genuine toss-up here — Laguna Beach's numbers don't point clearly either way.
How cold Laguna Beach actually gets
1159 heating degree days pile up here every year, so Laguna Beach barely has a winter to speak of; the cooling side runs to 804 cooling degree days, where summers add a moderate cooling load. 43°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 41°F on file. Worked through the model, that's a seasonal COP of 3.48 on the standard unit fit for this climate. Laguna Beach's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Source: NOAA station J.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 843 kWh a year to keep it warm, plus cooling, for a combined electric bill near $502 a year. Laguna Beach's gas rate of 22.01 per Mcf, applied to the 12 Mcf a year the furnace burns, puts its running cost near $608 a year, against 32.83¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 103.9 years, for a 15-year net position $588 ahead.
Electric resistance heat in Laguna Beach, compared
Plenty of homes in Laguna Beach heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Laguna Beach's answer improves. Switching saves about $804 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $5,500 spent up front comes back in about 6.8 years.
How Laguna Beach compares nationally
Laguna Beach lands at position 2829 out of 3206 cities on heating severity (coldest is 1), and 1747 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
