Virginia Beach, VA: the heat pump payback math
This one's marginal in Virginia Beach: it only clears if you stay long enough. $3,500 is what Virginia Beach 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. Virginia Beach's residents would see roughly $242 a year back in running costs, putting the payback around 14.5 years. It's a genuine toss-up here — Virginia Beach's numbers don't point clearly either way.
Virginia Beach's weather, in the numbers that matter
Degree days tell the story here: Virginia Beach racks up 2728 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1672 cooling degree days on the cooling side. 21°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 21°F on file. Worked through the model, that's a seasonal COP of 3.2 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Virginia Beach — 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 2,159 kWh a year to keep it warm, plus cooling, for a combined electric bill near $594 a year. Virginia Beach's gas rate of 16.79 per Mcf, applied to the 28 Mcf a year the furnace burns, puts its running cost near $836 a year, against 16.58¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 55.8 years; over 15 years the net position sits $130 ahead.
The other scenario: no gas furnace to begin with
Not every home in Virginia Beach 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. The saving here runs about $910 a year, which recovers the extra $8,000 spent going electric in roughly 8.8 years.
How Virginia Beach compares nationally
Among 3206 cities, Virginia Beach's winter puts it at rank 2021 for severity, while its size puts it at rank 43 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
