Sizing a mini-split in Houston County starts with the climate, not the catalog. 137 severe weather events were recorded in Houston County, Georgia between 2015 and 2024. At that rate, severe weather is a standing condition here, and a contractor quoting an installation has to account for what the system will be running against on a regular basis. An undersized unit will run at or near capacity far too often, stressing the compressor and shortening the life of the refrigerant circuit. A contractor who knows this area builds that load into the sizing calculation before anything else gets priced.
A house's electrical panel is the first thing a contractor opens before pricing a mini-split job here. Half the homes in Houston County, Georgia were built in 1994 or earlier (2020-2024 ACS 5-year). Wiring from that period was sized for what households ran then, and a mini-split needs a dedicated circuit that older panels sometimes lack the capacity to add without an upgrade. The ductwork question largely falls away with a mini-split, since the system needs none, but the electrical is a real variable that shapes both the scope and the price before the unit itself is ever ordered.
What a Mini-split Installation Puts in Your Home
The indoor unit mounts high on an interior wall in the room being conditioned, and it is the piece a homeowner sees every day. The outdoor unit sits on a pad or bracket outside the house and holds the compressor and condenser coil. Together these two units do the work of moving conditioned air into the space.
A refrigerant line set runs through a small hole in the wall to connect the indoor and outdoor units, bundled alongside a condensate drain line that carries moisture out of the building. A dedicated electrical disconnect is mounted near the outdoor unit as well, giving the contractor a local shutoff point for 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.

Houston County's climate puts real stress on heating and cooling equipment, and that stress shapes what a mini-split installation here needs to handle. A system sized and installed for local conditions is a different conversation than a generic one.
