Apple Valley, CA: the heat pump payback math
Apple Valley sits right on the fence — how long you'll own the house decides this one. $3,500 is what Apple Valley 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 $264 of lower running costs every year, landing the payback clock at roughly 13.3 years. It's a genuine toss-up here — Apple Valley's numbers don't point clearly either way.
How cold Apple Valley actually gets
Degree days tell the story here: Apple Valley racks up 2861 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2336 cooling degree days on the cooling side. 23°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 23°F on file. Worked through the model, that's a seasonal COP of 3.25 on the cold-climate unit fit for this climate. Apple Valley needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

The month-to-month numbers for Apple Valley
A 2000-square-foot house here would pull roughly 2,229 heating kilowatt-hours annually on top of cooling, totalling about $1,386 a year on electricity. Apple Valley's gas rate of 22.01 per Mcf, applied to the 30 Mcf a year the furnace burns, puts its running cost near $1,650 a year, against 32.83¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 51.1 years, leaving the 15-year total $461 ahead.
Electric resistance heat in Apple Valley, compared
Not every home in Apple Valley has gas service. Swap the comparison to resistance heat instead of gas, and Apple Valley's answer improves. Switching saves about $1,987 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4 years.
Where Apple Valley ranks in this dataset
Among 3206 cities, Apple Valley's winter puts it at rank 1963 for severity, while its size puts it at rank 514 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Apple Valley
Apple Valley, California is home to about 75,029 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 Apple Valley, nothing is lost by holding off until the current equipment genuinely fails.
