That 14F figure is the Fairfax County cold-day number a Fairfax Station heat pump is sized against, so ask the installer to show the system's heating output at 14F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Fairfax Station home has 10 rooms and was built around 1982, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
