Sizing a heat pump for Adams County starts with how deep winter actually runs here. Homes in Adams County, MS run heat about five months a year, from November through March. As outdoor temperatures drop through those months, a heat pump's capacity falls off, and a system sized too generously on paper will lean on its backup resistance elements to close the gap. A contractor running a proper load calculation has to establish both the peak cold demand and how the compressor performs at that low-end temperature before any equipment gets specified.
Ductwork laid down for a previous generation of equipment is what a contractor runs into across much of Adams County. Half the homes in Adams County, Mississippi were built in 1972 or earlier (2020-2024 ACS 5-year). A heat pump places different demands on a duct system than what most of these houses were originally built around, so a contractor installing one checks whether the existing runs can carry the required airflow before the new unit is ever quoted. If the ductwork falls short, that work lands on the bill before the equipment does.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the bulk of the work. Inside, the air handler mounts in a utility space, attic, or closet and moves conditioned air through the home. Together, these two units are what a heat pump installation physically adds to the structure.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that links the two. A thermostat goes on an interior wall and gives the homeowner control over the system. Some installations also include a disconnect box near the outdoor unit, which sits between the unit and the electrical supply.
The drawing shows a typical layout, and a licensed contractor determines exactly how these pieces are configured in your house.
