Is a heat pump worth it in Ukiah?
This one's marginal in Ukiah: it only clears if you stay long enough. $1,000 is what Ukiah 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. That premium is recovered through $78 of lower running costs every year, landing the payback clock at roughly 12.8 years. It's a genuine toss-up here — Ukiah's numbers don't point clearly either way.
How cold Ukiah actually gets
Degree days tell the story here: Ukiah racks up 2711 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1377 cooling degree days on the cooling side. 28°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 28°F on file. Worked through the model, that's a seasonal COP of 3.03 on the standard unit fit for this climate. Ukiah's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from UKIAH MUNICIPAL AIRPORT, the closest NOAA station, 1.4 miles out.
Ukiah's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,266 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,129 a year. Ukiah's gas rate of 22.01 per Mcf, applied to the 28 Mcf a year the furnace burns, puts its running cost near $1,207 a year, against 32.83¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 140.9 years, leaving the 15-year total $171 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Ukiah heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $1,710 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 3.2 years.
Where Ukiah ranks in this dataset
Ranked against the other 3206 cities covered, Ukiah comes in at 2032 for heating severity — 1 would be the coldest place in the dataset — and 2289 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
What to do with this number in Ukiah
Ukiah, California is home to about 16,067 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 Ukiah, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page — the 3.03 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Homes in Ukiah without gas service should read the electric-resistance comparison instead — the numbers there differ from the gas case above.
