Takes about a minute. No obligation.
A contractor quoting a mini-split installation in Houston County has to size the system for what this climate actually demands, not for what a catalog suggests for a house of a given square footage. 248 severe weather events were recorded in Houston County, Alabama between 2015 and 2024. At that rate of severe weather, the cooling load a system runs against here is a real variable, and a contractor who skips a proper load calculation is likely to leave a unit that short-cycles in mild conditions and falls behind when the weather turns hard. The spec sheet does not know where the house is.
Electrical panels in houses this old were sized for loads that bear little resemblance to what a mini-split draws today. Half the homes in Houston County, Alabama were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor quoting a mini-split installation here will size up the panel before pricing anything else, because undersized service means the new unit will not run correctly regardless of how well it is placed. The ductwork question does not apply to a ductless system, so the panel is where the job either opens cleanly or gets complicated.
What a Mini-split Installation Puts in Your Home
The indoor air handler mounts high on a wall inside the room being conditioned, where it delivers treated air directly into that space. The outdoor unit sits on the ground or a pad outside the house and holds the compressor and condenser coil. These two units are the core of what a contractor places during a mini-split installation.
A refrigerant line set runs between the indoor and outdoor units through a small opening in the wall, carrying the connection that makes both sides work as one system. A condensate drain line exits the indoor unit and routes moisture outside, and a dedicated electrical circuit feeds the outdoor unit from the service panel.
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 particular house.

Severe Weather Events in Houston County
Heating and cooling equipment in Houston County works against whatever the local climate delivers, and storm activity is part of that load. A mini-split sized and installed for conditions here has to hold up through what this area actually sees.
