Sizing a mini-split here is a local calculation, not a catalog one. 192 severe weather events were recorded in Baldwin County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition of operating in this county, and a contractor quoting an installation has to account for the sustained cooling and heating load that kind of climate puts on the equipment. A unit specified for a milder pattern of demand will run harder and longer than its rated capacity expects. The contractor gets that sizing right from the start, or the system spends its life catching up.
Electrical service is the variable a contractor works out first in a Baldwin County mini-split installation. Half the homes in Baldwin County, Alabama were built in 1999 or earlier (2020-2024 ACS 5-year). A house built around that time was wired for the demands of its era, and a mini-split's load requirements may not match what the panel was sized to deliver. If the panel is undersized or the circuits are already full, that gets resolved before the outdoor unit ever goes on the wall.
What a Mini-split Installation Puts in Your Home
The indoor air handler 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 the ground or a wall bracket outside the house, housing the compressor and the components that do the heavy mechanical work.
A contractor runs a conduit bundle through a small 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 that let the indoor and outdoor units work as one system.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and how the components are positioned within it.

Severe Weather Events in Baldwin County
Baldwin County's climate puts real demands on heating and cooling equipment, and those demands vary with what the weather actually does here year to year. A mini-split sized and installed for local conditions holds up better than one specified against a generic load.
