A contractor quoting a heat pump install in Chatham County has to treat the local climate as a design input, not an afterthought. 343 severe weather events were recorded in Chatham County, Georgia between 2015 and 2024. At that rate, severe weather is a recurring condition of operating in this area, and a system sized for a quieter environment will be undersized for what it actually faces here. Refrigerant charge, duct design, and equipment ratings all get set against what the climate actually demands, and what it demands is real.
Ductwork installed for an older cooling system carries assumptions about static pressure and airflow that a heat pump does not share, and those assumptions are built into the trunk lines, the branch runs, and the register sizes. Half the homes in Chatham County, Georgia were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation in this county opens the duct system before pricing the equipment, because what is behind the walls sets the scope as much as what goes on the pad outside.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners notice first. It sits outside on a pad or wall bracket and holds the compressor and one set of coils. Inside the house, the air handler mounts in a closet, attic, or utility space and moves conditioned air through the home. Together these two units do the work of the system.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that connects the two. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. Some installations also include a condensate drain line that carries moisture from the air handler to a drain point.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one fits the conditions of your particular house.

Heat pump performance is shaped by what the local climate actually demands of it, and that demand includes how often severe weather pushes the system hard. A contractor sizing and installing equipment here works from that local pattern.
