Sizing a heat pump for Lafayette County starts with the heating season, not the cooling one. Homes in Lafayette County, MS run heat about five months a year, from November through March. As outdoor temperatures drop toward their lowest point in January and February, a heat pump's capacity falls off, and a unit that looks adequate on paper may hand off to backup resistance heat far sooner than the homeowner expects. A contractor doing a proper load calculation here has to establish the coldest design conditions the system will face, then match the equipment's rated capacity at that temperature to the actual heat loss of the house. Get that wrong and the resistance strips carry a load they were meant to cover only briefly.
Ductwork sized and routed for an older system shapes whether a heat pump installation goes smoothly or requires additional work before the new unit ever runs. Half the homes in Lafayette County, Mississippi were built in 2000 or earlier (2020-2024 ACS 5-year). That puts a significant share of the housing stock in a range where the duct layout and the electrical service were designed around equipment with different demands than a modern heat pump carries. A contractor installing here checks what the existing ductwork can actually move and what the panel will support, and those two answers set the scope of the job.
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. Inside, the air handler mounts in a mechanical room, closet, or attic and pushes conditioned air through the house. Together these two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.
