Takes about a minute. No obligation.
Sizing a mini-split here starts with what the house demands, not with a worst-case weather scenario. 96 severe weather events were recorded in Ritchie County, West Virginia between 2015 and 2024. That puts this county close to the middle of the national picture, which means a contractor is not sizing around an unusually punishing outdoor load. The refrigerant line routing, the wall penetration seal, and the unit placement are the variables that decide how well the system performs and holds up, and those are determined by the specific structure, not by a regional weather premium.
Electrical service is where a mini-split installation in Ritchie County either opens up or stalls. Half the homes in Ritchie County, West Virginia were built in 1975 or earlier (2020-2024 ACS 5-year). Panels in houses of that era were sized for a different set of loads than a modern mini-split draws, and a contractor has to read what is actually in the box before the job can be priced or scheduled. Ductwork is beside the point for a ductless system, so the electrical is the variable that decides the scope here.
What a Mini-split Installation Covers in Your Home
The indoor air handler mounts high on a wall inside the room being conditioned, and it is the piece a homeowner sees and lives with every day. The outdoor unit sits on the ground or on a wall bracket outside the house, and it is where the compressor and most of the mechanical work live.
A refrigerant line set runs between the two units through a small hole in the wall, carrying the working fluid back and forth. A condensate drain line runs from the indoor unit to move moisture out, and a dedicated electrical circuit feeds the outdoor unit from the panel.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation involves for your specific house.
