Sizing a mini-split in Hanover County starts with what the equipment will actually face year after year. 126 severe weather events were recorded in Hanover County, Virginia between 2015 and 2024. At that rate, a contractor cannot pull a load calculation straight from a floor plan and call it done. Severe weather raises peak demand and shortens the margin between a system that keeps up and one that runs behind its own schedule. A contractor who skips that step installs a unit sized for a calmer place.
The wiring already in the walls is where a mini-split installation either goes smoothly or stalls. Half the homes in Hanover County, Virginia were built in 1991 or earlier (2020-2024 ACS 5-year). Houses built for the appliance loads of that era carry electrical service that a contractor has to measure against what a modern mini-split actually draws before any equipment gets ordered. Ductwork is beside the point for a mini-split, so the panel and the branch circuits take its place as the first thing opened and priced.
What a Mini-split Installation Covers
The indoor air handler mounts high on a wall inside the room being served, which is where most homeowners notice the system first. It draws in room air, conditions it, and delivers it back. The outdoor condenser unit sits on a pad or bracket outside the house and carries the compressor and the main refrigerant components.
A refrigerant line set runs through a small penetration in the wall to connect the two units, carrying refrigerant between them. A condensate drain line runs from the indoor head to an appropriate discharge point, and a dedicated power supply feeds the outdoor unit directly.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one is positioned and routed for your specific home.
