Heating design temperature: 28F.

That 28F figure is the St. Tammany Parish cold-day number a Slidell heat pump is sized against, so ask the installer to show the system's heating output at 28F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Slidell home has 6 rooms and was built around 1979, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
