Heat pump vs. gas furnace in Norfolk, VA
In Norfolk, the math is close enough that it comes down to how long you plan to stay. $3,500 is what Norfolk 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. Norfolk's residents would see roughly $252 a year back in running costs, putting the payback around 13.9 years. It's a genuine toss-up here — Norfolk's numbers don't point clearly either way.
How cold Norfolk actually gets
Norfolk has a mild winter by US standards — 2499 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1881 cooling degree days. 23°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 3.25 on the cold-climate unit fit for this climate. Norfolk 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. These numbers come from NORFOLK NAS, the closest NOAA station, 2.6 miles out.
Norfolk's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,947 kWh a year to keep it warm, plus cooling, for a combined electric bill near $589 a year. The gas furnace it replaces burns roughly 26 Mcf a year at 16.79 per Mcf here, for a running cost near $841 a year (electricity here runs 16.58¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 53.5 years, leaving the 15-year total $287 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Norfolk heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $865 a year, which recovers the extra $8,000 spent going electric in roughly 9.3 years.
How Norfolk compares nationally
Ranked against the other 3206 cities covered, Norfolk comes in at 2181 for heating severity — 1 would be the coldest place in the dataset — and 100 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Norfolk, Virginia is home to about 231,105 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Norfolk, nothing is lost by holding off until the current equipment genuinely fails.

Where Norfolk's figure comes from
The methodology guide walks through exactly how Norfolk's 3.25 seasonal COP and the rest of this page's numbers get built. Norfolk's 23°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.
