Palmdale, CA: the heat pump payback math
Palmdale sits right on the fence — how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $312 saved annually, for a payback of roughly 11.2 years. It's a genuine toss-up here — Palmdale's numbers don't point clearly either way.
How cold Palmdale actually gets
2641 heating degree days pile up here every year, so Palmdale has a mild winter by US standards; the cooling side runs to 2583 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 24.1°F, against a record low of 23°F. That puts the seasonal coefficient of performance at 3.28 for the recommended cold-climate unit. Palmdale 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. Climate figures trace to the nearest NOAA station, PDLE PRODN FLT/TST AF PLT, 2.9 miles from Palmdale.
The month-to-month numbers for Palmdale
A 2000-square-foot house here would pull roughly 2,039 heating kilowatt-hours annually on top of cooling, totalling about $1,392 a year on electricity. The gas furnace it replaces burns roughly 28 Mcf a year at 22.01 per Mcf here, for a running cost near $1,704 a year (electricity here runs 32.83¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 43.3 years, leaving the 15-year total $1,180 ahead.
Electric resistance heat in Palmdale, compared
Plenty of homes in Palmdale heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Palmdale's answer improves. About $1,902 a year comes back this way, enough that the 4.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Palmdale ranks in this dataset
Palmdale lands at position 2072 out of 3206 cities on heating severity (coldest is 1), and 163 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Palmdale's figure comes from
The methodology guide walks through exactly how Palmdale's 3.28 seasonal COP and the rest of this page's numbers get built. Palmdale's 24.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
