A contractor quoting a mini-split installation in Fulton County has to treat the local weather record as a design input, not a footnote. 218 severe weather events were recorded in Fulton County, Georgia between 2015 and 2024. At that rate, severe weather here is a standing operating condition, and a system sized for a calmer climate will be running near its ceiling on the days it is needed most. Refrigerant line routing, mounting position, and outdoor unit placement all carry different stakes when the equipment will face that kind of sustained load. A contractor who prices the job without accounting for those variables is quoting the wrong job.
Electrical panels in a large share of Fulton County homes were sized for the demands of an era before modern mini-split systems became common, and what a panel can actually supply is the variable a contractor has to confirm before a quote means anything. Half the homes in Fulton County, Georgia were built in 1993 or earlier (2020-2024 ACS 5-year). A house built then was wired for equipment with different load profiles than what a multi-zone mini-split draws today, and the panel may or may not have room for the new circuit without an upgrade. That single question shapes the scope and the price of the installation more than the equipment selection does.
What a Mini-split Involves at Each Part of the System
The indoor air handler mounts on a wall inside the room being served, high enough to distribute air across the space. It holds the coil and fan that condition the air directly where you need it. The outdoor unit sits on a pad or bracket outside the house and houses the compressor and second coil.
A conduit runs through a small hole in the wall to connect the two units, carrying the refrigerant lines, a condensate drain line, and the power and signal wiring together in one bundle. A disconnect box goes on the exterior wall near the outdoor unit, giving a contractor a safe shutoff point close to the equipment.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

Fulton County's weather puts real demands on heating and cooling equipment, and those demands shape what a system needs to handle over its life. Sizing and installing a mini-split here is a local decision, and local conditions are part of it.
