Heat pump vs. gas furnace in Cranston, RI
Cranston is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Cranston 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. The heat pump would cost about $31 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Cranston's numbers say wait.
Why Cranston's climate drives this number
5140 heating degree days pile up here every year, so Cranston has a cold winter that leans hard on heating equipment; the cooling side runs to 708 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 12°F, against a record low of 9°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. Cranston 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, THEODORE F GREEN STATE AIRPOR, 4.2 miles from Cranston.
The month-to-month numbers for Cranston
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,353 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,461 a year. The gas furnace it replaces burns roughly 54 Mcf a year at 21.66 per Mcf here, for a running cost near $1,430 a year (electricity here runs 29.48¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $3,968 behind.
Electric resistance heat in Cranston, compared
Gas isn't universal in Cranston — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Cranston's answer improves. About $2,646 a year comes back this way, enough that the 3-year payback clears the $8,000 premium comfortably within the equipment's life.
How Cranston compares nationally
Among 3206 cities, Cranston's winter puts it at rank 588 for severity, while its size puts it at rank 430 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Cranston's 2.99 seasonal COP and payback figure. Cranston's 12°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
