That 18F figure is the Sussex County cold-day number a Dewey Beach heat pump is sized against, so ask the installer to show the system's heating output at 18F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Dewey Beach home has 5.3 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
