Is a heat pump worth it in Graham?
This one's marginal in Graham: it only clears if you stay long enough. $3,500 is what Graham 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. Graham's residents would see roughly $242 a year back in running costs, putting the payback around 14.5 years. Whether that's worth it in Graham depends on how many years you expect to own the place.
Why Graham's climate drives this number
Degree days tell the story here: Graham racks up 3063 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1461 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 15.1°F, against a record low of 12°F. That puts the seasonal coefficient of performance at 3.06 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Graham sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from BURLINGTON ALAMANCE RGL AP, the closest NOAA station, 4.9 miles out.
Graham's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,535 kWh a year to keep it warm, plus cooling, for a combined electric bill near $564 a year. The gas furnace it replaces burns roughly 32 Mcf a year at 16.42 per Mcf here, for a running cost near $806 a year (electricity here runs 14.93¢/kWh). Buy it outright, not incrementally, and payback stretches to 55.8 years; over 15 years the net position sits $131 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Graham has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $876 a year comes back this way, enough that the 9.1-year payback clears the $8,000 premium comfortably within the equipment's life.
Graham against the rest of the country
Among 3206 cities, Graham's winter puts it at rank 1898 for severity, while its size puts it at rank 1986 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Where Graham's figure comes from
The methodology guide walks through exactly how Graham's 3.06 seasonal COP and the rest of this page's numbers get built. Graham's 15.1°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.
