Sizing a heat pump for Berrien County means answering for real, recurring load. 103 severe weather events were recorded in Berrien County, Georgia between 2015 and 2024. At that rate, severe weather is part of normal operating life for every system in the county, and a contractor who ignores that will undersize the equipment or spec components that cannot sustain the demand. A unit that is correctly sized and properly installed from the start handles that load without running at the edge of its capacity every season.
Ductwork laid down for older heating and cooling equipment carries assumptions about airflow that a heat pump does not share. Half the homes in Berrien County, Georgia were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump in stock of this vintage checks whether the existing ducts move enough air at the right static pressure for the new system, because a mismatch there affects comfort and efficiency in ways the unit itself cannot compensate for. Electrical service gets the same look: the panel and the wiring run to the outdoor unit both get assessed before anything is quoted.
The Parts of a Heat Pump System and What Gets Installed
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the condenser coil, which do the core work of moving heat between outside air and the refrigerant. Inside the house, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set connects the two units, running through the wall or exterior of the house to carry refrigerant back and forth between them. A thermostat on an interior wall gives the homeowner control over the whole system, and a condensate drain line carries moisture pulled from the indoor air out of the house.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which configuration and components apply to this particular house.

Weather puts direct load on heating and cooling equipment, and that load shapes what a heat pump here has to handle year after year. How hard a system works, and how well it needs to be sized and installed, is a local question.
