Takes about a minute. No obligation.
Sizing a mini-split in Tattnall County means working out what the system will run against for years, and the weather record here is part of that calculation. 76 severe weather events were recorded in Tattnall County, Georgia between 2015 and 2024. At that rate, severe weather is a standing condition for any outdoor unit in this county, and a contractor has to factor that into where the unit is placed, how it is mounted, and which components are specified. A unit undersized or poorly positioned for this environment will be working at its limit before it is old.
Electrical service is what a contractor looks at first when sizing a mini-split for a house in this county. Half the homes in Tattnall County, Georgia were built in 1987 or earlier (2020-2024 ACS 5-year). Wiring put in for the loads of that era was not sized around the dedicated circuits a modern mini-split outdoor unit draws, and a panel that looked sufficient for everything else in the house can fall short once the new equipment is factored in. The ductwork question does not apply to a mini-split the same way it does to a forced-air system, so the electrical panel moves to the front of what gets priced and opened.
What a Mini-split Installation Puts in Your Home
The indoor air handler mounts high on a wall inside the room being conditioned, where it draws in room air and delivers treated air back out. The outdoor unit sits on the ground or a wall bracket outside the house and holds the compressor and condenser coil, which do the heavy mechanical work of the system.
A conduit bundle carrying refrigerant lines, a condensate drain line, and low-voltage signal wiring runs through a small hole in the wall to connect the two units. A dedicated disconnect box is mounted on the exterior wall near the outdoor unit, giving a contractor a local shutoff point for service.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your house.

Weather puts a measurable load on heating and cooling equipment, and that load varies by location. What the climate does in Tattnall County shapes how hard a mini-split has to work and how a contractor sizes and installs it here.
