Should Perris switch to a heat pump?
Perris 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. That premium is recovered through $139 of lower running costs every year, landing the payback clock at roughly 7.2 years. That's a real payback, built from Perris's own climate and utility rates, not a national guess.
Why Perris's climate drives this number
Degree days tell the story here: Perris racks up 2272 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1657 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 28°F here (record low 27.1°F), which works out to a seasonal COP of 3.03 for the standard class of unit this climate calls for. A standard ducted system is enough here; Perris's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, MARCH AIR RESERVE BASE, 7.8 miles from Perris.
Perris's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 1,899 heating kilowatt-hours annually on top of cooling, totalling about $1,087 a year on electricity. That compares with roughly 24 Mcf a year of gas at Perris's 22.01 per-Mcf rate — about $1,226 a year — against a local electricity rate of 32.83¢/kWh. Buy it outright, not incrementally, and payback stretches to 79.3 years; over 15 years the net position sits $1,080 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Perris heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Perris's answer improves. About $1,507 a year comes back this way, enough that the 3.7-year payback clears the $5,500 premium comfortably within the equipment's life.
Perris against the rest of the country
Ranked against the other 3206 cities covered, Perris comes in at 2289 for heating severity — 1 would be the coldest place in the dataset — and 443 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.
