Sizing a heat pump for Issaquena County requires a contractor to work out what happens at the cold end of the season, not just the average of it. Homes in Issaquena County, MS run heat about five months a year, from November through March. Capacity falls as outdoor temperatures fall, so a unit that tests fine in mild weather can fall short on the coldest nights in January or February. A contractor has to establish what backup heat the system carries and how the controls hand off between the two, because an undersized or poorly staged install will cycle the backup strip more than it should, driving up the power draw across the whole heating season.
Ductwork in houses like these was not designed for heat pump load patterns. It was adapted over time, each swap adding a layer the next contractor has to read before anything else. Half the homes in Issaquena County, Mississippi were built in 1983 or earlier (2020-2024 ACS 5-year). That history means a contractor quoting a heat pump installation has to assess the existing duct runs and the electrical service before settling on equipment, because both were configured for something earlier. A panel or a duct configuration that worked before can fall short of what the new unit needs.
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 heat exchange coil, which are the two pieces doing the heaviest work. Inside, an air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. Together these are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that connects both sides of the system. A thermostat goes on an interior wall where it reads the air and signals the system to run. The condensate drain line exits the air handler and routes moisture out of the house.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to your home and its existing setup.
