Takes about a minute. No obligation.
A contractor quoting a mini-split installation in Franklin County works out the actual thermal load before touching a spec sheet, because the equipment will run against real conditions here, not averaged ones. 112 severe weather events were recorded in Franklin County, Alabama between 2015 and 2024. Severe weather at that frequency means the system gets pushed hard across its life, and a unit sized or installed without accounting for that load will underperform before its time. Refrigerant line routing, mounting placement, and unit capacity are all local questions here.
Electrical panels in much of this county's housing were sized for whatever was running at the time the house was built, and a mini-split draws differently from what those panels were designed around. Half the homes in Franklin County, Alabama were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor here will open the panel and measure what is actually available before the equipment conversation begins, because a panel that falls short changes the scope and the price of the job. The ductwork question does not apply to a mini-split, but the electrical one does, and in stock of this vintage it is the variable that decides how the installation goes.
What a Mini-split Installation Puts in Your Home
The indoor air handler mounts high on an interior wall, inside the room being conditioned, and moves treated air directly into that space. The outdoor unit sits on a pad or bracket outside the house and holds the compressor and condenser coil. These two pieces are the core of what a contractor installs.
A refrigerant line set runs through a small hole in the wall to connect the indoor and outdoor units, carrying the working fluid between them. A condensate drain line runs from the indoor unit to the outside, pulling away any moisture the system collects. A dedicated electrical circuit feeds the outdoor unit.
The drawing beside this text shows the general layout of a mini-split system, and a licensed contractor determines exactly how each piece is positioned and configured for your specific home.

Severe Weather Events in Franklin County
Local weather puts real demands on heating and cooling equipment, and those demands shape what a system needs to handle over its life. A mini-split sized and installed for this climate is a different proposition than one spec'd somewhere else.
