Our estimate for this home
It depends on your quotes. A heat pump saves about $210 a year to run, so it comes out ahead over 15 years if its quote is no more than $3,100 above the quote for a new furnace and AC.

Appalachian Power's electricity price for a typical home is close to the Virginia average ($0.170 vs. $0.167 per kWh). A heat pump moves your heating from gas to electricity, so the electricity price is the biggest single factor: calculators that use a state average can get the answer wrong for your utility. At these prices, a heat pump is cheaper to run for a typical home here.
Your home's yearly heating and cooling need comes from 1991-2020 NOAA climate normals for the nearest weather station, scaled by floor area and insulation level. If you know last winter's gas use, compare it with the therms in the energy-use list above.
New furnace 95% AFUE; new AC SEER2 13.4; standard heat pump SEER2 15.2 / HSPF2 7.8; high-efficiency cold-climate heat pump SEER2 21.5 / HSPF2 10.6. Heat pump efficiency falls as it gets colder, and in cold months part of the heat comes from backup electric strips (or your old furnace, if you keep it). Existing equipment is assumed to be a 15-20 year old 80% furnace or SEER2 9.5 AC.
Installed prices vary a lot, so we show a typical price and a range for a home of about 1,800 sq ft with existing ductwork, scaled for larger or smaller homes: furnace and AC together $9,000–$14,000; furnace alone $3,800–$7,000; AC alone $4,500–$9,000; standard heat pump $8,000–$15,000; high-efficiency cold-climate heat pump $11,000–$20,000; electrical panel upgrade, if needed, $1,500–$4,000. These are national figures drawn from published studies and program data (NESCAUM / Energy Solutions, Heat Pumps in the Northeast and Mid-Atlantic: Costs and Market Trends (October 2024); Rewiring America, Upfront cost of home electrification (March 2024); EIA, Updated Buildings Sector Appliance and Equipment Costs and Efficiencies (2023)). The most useful number here is how much more a heat pump can cost than a like-for-like quote and still come out ahead: get quotes for both and compare.
Half of each installed price is treated as labor and scaled by the state's median HVAC installer wage relative to the U.S. median (U.S. Bureau of Labor Statistics). Listed rebates are subtracted when the box is ticked; per-ton rebates assume about one ton of capacity per 600 sq ft. Rebates change often and have eligibility rules, so confirm with the program before you buy.
