Getting the size right on a mini-split in Jackson County depends on more than square footage. 82 severe weather events were recorded in Jackson County, West Virginia between 2015 and 2024. That record puts real seasonal stress on a system, but it sits at a level where installation decisions, not weather alone, decide how well a unit holds up over time. A contractor who shortcuts the load calculation or cuts corners on the line set is building in problems that the weather will eventually expose. Proper sizing, a clean refrigerant charge, and solid mounting are what a licensed installer has to get right here.
Electrical service sized for older equipment is what a mini-split contractor runs into first in much of Jackson County. Half the homes in Jackson County, West Virginia were built in 1979 or earlier (2020-2024 ACS 5-year). What was standard when those houses were wired was not sized with a modern inverter-driven system in mind, so before any unit gets spec'd or priced, the contractor checks whether the panel can carry the new load. Ductwork is beside the point here, since mini-splits run without it, but the electrical is not optional.
The Mini-split Parts a Contractor Works With During Installation
The indoor air handler mounts high on an interior wall in the room being served, and it is the piece the occupants see every day. The outdoor condenser unit sits on a pad or brackets outside the house, typically along an exterior wall. Together these two units form the core of what a contractor brings to the job.
A refrigerant line set runs through a small penetration in the wall and connects the indoor and outdoor units. A condensate drain line runs from the air handler to a suitable discharge point, and the electrical line from the disconnect box ties into the outdoor unit.
The drawing shows a standard layout, and a licensed contractor determines exactly how each piece fits and routes within your home.

Severe Weather Events in Jackson County
Heating and cooling equipment carries the full load of whatever the local climate demands, and that demand is shaped by how hard the weather pushes. A mini-split sized and installed for what Jackson County actually sees will hold up differently than one specified for somewhere else.
