Wasco, CA: the heat pump payback math
In Wasco, a heat pump is the cheaper choice, and not by a little. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Wasco's residents would see roughly $371 a year back in running costs, putting the payback around 2.7 years. Nothing about that conclusion is generic — it's built entirely from Wasco's own numbers.
The climate behind Wasco's payback figure
1909 heating degree days pile up here every year, so Wasco has a mild winter by US standards; the cooling side runs to 3003 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 32°F, against a record low of 32°F. That puts the seasonal coefficient of performance at 3.15 for the recommended standard unit. A standard ducted system is enough here; Wasco's design temperature doesn't justify the cold-climate premium.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,535 heating kilowatt-hours annually on top of cooling, totalling about $1,344 a year on electricity. Wasco's gas rate of 22.01 per Mcf, applied to the 20 Mcf a year the furnace burns, puts its running cost near $1,715 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 29.7 years, for a 15-year net position $4,564 ahead.
The other scenario: no gas furnace to begin with
Not every home in Wasco has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,520 a year, which recovers the extra $5,500 spent going electric in roughly 3.6 years.
How Wasco compares nationally
Ranked against the other 3206 cities covered, Wasco comes in at 2471 for heating severity — 1 would be the coldest place in the dataset — and 1461 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
