That 26F figure is the Berkeley County cold-day number a Moncks Corner heat pump is sized against, so ask the installer to show the system's heating output at 26F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Moncks Corner home has 6.3 rooms and was built around 2007, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
