With 96% detached houses and 3% in small multi-family buildings, a Madisonville quote is usually one or two outdoor units with ducted or ductless heads sized room by room.

Heating design temperature: 28F.

That 28F figure is the St. Tammany Parish cold-day number a Madisonville 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 whether the quote is whole-home or partial-home, because with 68% of Madisonville on gas and 29% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Madisonville home has 6.2 rooms and was built around 1994, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
