A contractor quoting a mini-split installation in Greene County has to settle one question first: what is the system actually being sized against? 117 severe weather events were recorded in Greene County, Virginia between 2015 and 2024. That puts severe weather in this area at a real but not extreme pace, which means the climate alone does not drive the sizing decision the way it would in a harder-hit region. What drives it is the quality of the original install and how well the load calculation fits the house. A contractor who skips that math and defaults to a catalog size leaves the homeowner with a system that runs wrong from day one.
The electrical panel in a house of this vintage was sized for a different era's equipment, and a mini-split draws power in a pattern that older service panels were not designed around. Half the homes in Greene County, Virginia were built in 1994 or earlier (2020-2024 ACS 5-year). A contractor installing a ductless system here checks the panel before anything else, because the unit can be matched perfectly to the space and still stall at the breaker box. That single variable shapes the scope and the price of the job more than the equipment selection does.
What a Mini-split Installation Covers
The indoor air handler mounts high on a wall inside the room, which is where most homeowners notice it first. It pulls in room air, conditions it, and pushes it back out. The outdoor unit sits on a pad or bracket outside the house and holds the compressor and condenser coil.
A refrigerant line set runs through a small hole in the wall to connect the two units, carrying refrigerant between them. A condensate drain line runs from the indoor unit to carry away moisture, and a dedicated electrical circuit feeds the outdoor unit from the panel.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one applies to your house.
