Sizing and installing a heat pump correctly here means working out what the local climate actually demands, not borrowing assumptions from somewhere else. 25 severe weather events were recorded in Lamar County, Georgia between 2015 and 2024. At that rate, severe weather is an event a system might see, not a persistent load shaping every season. A contractor quoting a new install in Lamar County will spend more time on duct layout, insulation quality, and load calculations tied to the structure than on hardening a unit against routine storm stress. Age of the equipment and quality of the original installation account for most of what goes wrong here.
Ductwork sized and routed for an older system often runs fine until a contractor checks it against what a heat pump actually needs to move conditioned air through the house. Half the homes in Lamar County, Georgia were built in 1988 or earlier (2020-2024 ACS 5-year). That gap between when these houses were built and what gets installed in them now is where installation scope expands: duct runs that were adequate for one type of system may need sealing, resizing, or rerouting to handle the airflow a heat pump delivers. Electrical service is the other variable a contractor pulls up before the quote is final.
The Parts of a Heat Pump System Involved in an Installation
The outdoor unit is the piece most homeowners recognize first. It sits on a pad outside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, a closet, or an attic and pushes conditioned air through the home.
The refrigerant lines run between the outdoor unit and the air handler, carrying refrigerant back and forth through the system. A thermostat on an interior wall gives the homeowner control over the whole setup, and a condensate drain line runs from the air handler to carry away moisture that collects during cooling.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

Weather puts a direct load on heating and cooling equipment, and that load shapes what a heat pump here needs to handle over its working life. Sizing and installation decisions are local ones because the climate conditions are local.
