Sizing a heat pump for Tate County starts with what the equipment is asked to do in the coldest part of the heating season, when outdoor temperatures fall and the unit's capacity drops with them. Homes in Tate County, MS run heat about five months a year, from November through March. The compressor and reversing valve carry that load every cycle, and a unit undersized at installation runs harder than it should all winter, not coasting. A contractor doing a load calculation here has to account for that cold-end performance gap before settling on equipment, because back-up heat is a real question, not a default checkbox. The install spec follows from the answer.
Ductwork laid down for a furnace and central AC pair moves air differently than a heat pump needs it to. Half the homes in Tate County, Mississippi were built in 1992 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a new heat pump here has to look at what the existing ducts can actually carry before settling on equipment, not after. Return air, static pressure, and the path the supply runs take through the house are all set by decisions made for a system that is no longer in it. Getting those wrong produces a unit that performs below its rated output regardless of how well it is installed.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil, the two components that do the heaviest work. Inside, an air handler or indoor coil mounts in a utility space or closet and connects to the outdoor unit through a pair of refrigerant lines that run through the wall.
A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run. A condensate drain line runs from the indoor unit to a floor drain or outside, carrying away the moisture the coil pulls from the air during cooling.
The drawing beside this text shows how those pieces relate to one another in a typical installation, and a licensed contractor determines exactly how they come together in your house.
