A mini-split going into Chatham County is being sized for a climate where severe weather is part of the baseline, not an exception a contractor plans around. 343 severe weather events were recorded in Chatham County, Georgia between 2015 and 2024. At that rate, every system installed here spends its service life running against conditions that push capacity and strain refrigerant lines and mounts. A contractor quoting an install here works out what the equipment will carry in normal operation before they settle on unit size or placement. That is a field judgment, not a spec-sheet lookup, and the install either reflects it or it does not.
Ductwork laid down for central air in an older house was sized and routed for that system, and a mini-split does not use it the same way. Half the homes in Chatham County, Georgia were built in 1986 or earlier (2020-2024 ACS 5-year). That matters for installation because a contractor has to determine what the existing distribution can do before the new equipment is even selected, and in a house that old the electrical service is its own separate question. A panel that was spec'd for one load profile gets measured against what the new unit actually draws, and that measurement shapes the quote.
What a Mini-split Installation Puts in Your Home
The indoor air handler mounts high on a wall inside the room being served, pulling in room air and delivering conditioned air back into the space. The outdoor condenser unit sits on the ground or a bracket outside the house, shedding heat to the exterior. Together these two pieces are the core of what a contractor installs.
A pair of refrigerant lines runs through a small opening in the wall to connect the indoor and outdoor units, and a condensate drain line carries moisture from the indoor unit to the outside. A disconnect box is mounted near the outdoor unit to give the electrical supply a dedicated shutoff point at the equipment.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your specific home.

Weather puts real demands on heating and cooling equipment, and those demands are specific to where you live. A mini-split sized and installed for local conditions holds up better and works harder for longer than one that was not.
