That 20F figure is the Shelby County cold-day number a Collierville heat pump is sized against, so ask the installer to show the system's heating output at 20F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 61% of Collierville on gas and 38% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Collierville home has 7.7 rooms and was built around 1998, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
