That 12F figure is the Robertson County cold-day number a Springfield heat pump is sized against, so ask the installer to show the system's heating output at 12F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Springfield home has 5.2 rooms and was built around 1987, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
