Will a heat pump pay off in Roseville, CA?
Roseville clears a genuine payback here, inside a reasonable stretch of years. 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. Roseville's residents would see roughly $201 a year back in running costs, putting the payback around 5 years. That's a real payback, built from Roseville's own climate and utility rates, not a national guess.
Why Roseville's climate drives this number
Degree days tell the story here: Roseville racks up 2314 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1857 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 33.8°F here (record low 32°F), which works out to a seasonal COP of 3.21 for the standard class of unit this climate calls for. A standard ducted system is enough here; Roseville's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, SACRAMENTO MCCLELLAN AFB, 8.3 miles from Roseville.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,825 heating kilowatt-hours annually on top of cooling, totalling about $1,119 a year on electricity. The gas furnace it replaces burns roughly 24 Mcf a year at 22.01 per Mcf here, for a running cost near $1,321 a year (electricity here runs 32.83¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 54.6 years, leaving the 15-year total $2,022 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Roseville — many houses run on electric heat already. 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 $1,595 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 3.4 years.
Where Roseville ranks in this dataset
Roseville lands at position 2268 out of 3206 cities on heating severity (coldest is 1), and 162 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.

About 163,304 people live in Roseville, California, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, it's worth getting quotes before your current system fails, not after.
Ask a local HVAC contractor for a quote before committing either way.
