Heat pump vs. gas furnace in Winchester, VA
In Winchester, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $237 of lower running costs every year, landing the payback clock at roughly 14.8 years. Whether that's worth it in Winchester depends on how many years you expect to own the place.
Why Winchester's climate drives this number
4502 heating degree days pile up here every year, so Winchester has a real but manageable winter; the cooling side runs to 976 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 14°F here (record low 5°F), which works out to a seasonal COP of 3.04 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Winchester sits firmly in cold-climate territory, so that's the class of unit priced here.

Winchester's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,750 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $760 a year. That compares with roughly 47 Mcf a year of gas at Winchester's 16.79 per-Mcf rate — about $997 a year — against a local electricity rate of 16.58¢/kWh. Buy it outright, not incrementally, and payback stretches to 56.9 years; over 15 years the net position sits $59 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Winchester heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,340 a year comes back this way, enough that the 6-year payback clears the $8,000 premium comfortably within the equipment's life.
Winchester against the rest of the country
Among 3206 cities, Winchester's winter puts it at rank 1196 for severity, while its size puts it at rank 1441 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
