Sizing a mini-split here starts with what the outdoor unit will actually face, and that question has a concrete answer for this county. 75 severe weather events were recorded in Winston County, Alabama between 2015 and 2024. At that rate, severe weather is a standing operating condition, not a rare interruption, which means the placement of the outdoor unit and the rated capacity of each head are decisions made against real and regular load. A contractor quoting an install in Winston County factors that in before specifying equipment.
Electrical service is what decides how a mini-split installation goes in Winston County. Half the homes in Winston County, Alabama were built in 1988 or earlier (2020-2024 ACS 5-year). A house built by that year was wired for the loads of that era, and a ductless system draws on a dedicated circuit that older panels were not always laid out to give. A contractor here sizes the new unit and then opens the electrical to find out whether the service can carry it, or whether panel work comes first.
What Gets Installed With a New Mini-split
The indoor air handler mounts on an interior wall, high enough to distribute conditioned air across the room. It is the piece a homeowner sees every day. The outdoor condenser unit sits on a pad or bracket outside the house and holds the compressor and the coils that do the heavy work.
A small bundle of lines runs through a drilled opening in the wall to connect the two units. That bundle carries the refrigerant lines, a condensate drain line, and the power and communication wiring. A contractor also mounts the wall bracket and thermostat or control receiver that completes the installation.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines exactly how each piece is positioned and routed for your specific house.
