A heat pump sized for average conditions in a gentler climate will run harder and cycle more often in a place where severe weather arrives regularly. 70 severe weather events were recorded in Cook County, Georgia between 2015 and 2024. At that rate of exposure, the load a system carries over its life is real, and a contractor who ignores it when selecting equipment and sizing the install is quoting for the wrong county. Refrigerant line sizing, defrost settings, and equipment ratings all shift when the baseline load is higher than a manufacturer's default assumptions.
Ductwork laid down for an older forced-air system carries assumptions about airflow, return sizing, and routing that a heat pump does not share. Half the homes in Cook County, Georgia were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor scoping a heat pump installation here checks what those ducts will actually deliver before pricing the unit, because a system that outpaces its ductwork will run short of its rated output regardless of what the nameplate says. Electrical service gets the same early look, since heat pumps draw differently than the resistance heat or gas-paired systems many of these houses were built around.
What a Heat Pump Installation Covers
The outdoor unit sits on a concrete pad or wall bracket beside the house and holds the compressor and coil that do the core work. Inside, an air handler mounts in a closet, attic, or utility space and moves conditioned air through the home. These two units are what a contractor sets in place.
A pair of refrigerant lines runs between the outdoor unit and the air handler, connecting the two halves of the system. A thermostat goes on an interior wall and gives the homeowner control over the whole setup. Some homes also take a separate disconnect box near the outdoor unit as part of the same job.
The drawing shows the general layout of these components, and a licensed contractor determines exactly what applies to this house.

Local weather conditions set the real workload for any heat pump installed here. Equipment sized and specified for what this area actually sees will hold up better and run more efficiently than gear chosen without that context.
