Heat pump vs. gas furnace in Salem, VA
Salem sits right on the fence — how long you'll own the house decides this one. $3,500 is what Salem 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. Lower bills claw that back: about $236 saved annually, for a payback of roughly 14.8 years. Whether that's worth it in Salem depends on how many years you expect to own the place.
Why Salem's climate drives this number
Degree days tell the story here: Salem racks up 3283 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1533 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 15.1°F here (record low 12.9°F), which works out to a seasonal COP of 3.06 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Salem — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,717 kWh a year to keep it warm, plus cooling, for a combined electric bill near $667 a year. Salem's gas rate of 16.79 per Mcf, applied to the 34 Mcf a year the furnace burns, puts its running cost near $903 a year, against 16.58¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 57.1 years; over 15 years the net position sits $45 ahead.
Electric resistance heat in Salem, compared
Plenty of homes in Salem heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Salem's answer improves. About $1,041 a year comes back this way, enough that the 7.7-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Salem ranks in this dataset
Among 3206 cities, Salem's winter puts it at rank 1828 for severity, while its size puts it at rank 1546 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
