Heating design temperature: 33F.

That 33F figure is the Hernando County cold-day number a Spring Hill heat pump is sized against, so ask the installer to show the system's heating output at 33F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Spring Hill home has 5.8 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
