Takes about a minute. No obligation.
Sizing a mini-split for this county means accounting for a climate that puts real, recurring load on the system. 109 severe weather events were recorded in Genesee County, Michigan between 2015 and 2024. A contractor quoting an install here cannot pull a number from a catalog and call it done. Outdoor unit placement, refrigerant line routing, and the capacity of the indoor head all get set against what the equipment will actually run against in this area, not against what works in a milder place.
Electrical panels in much of this county's housing were sized for the loads of a different era, and a mini-split draws on a dedicated circuit that older service may not have room to add without an upgrade. Half the homes in Genesee County, Michigan were built in 1969 or earlier (2020-2024 ACS 5-year). A contractor quoting a mini-split installation here opens the breaker panel before anything else, because what it contains determines whether the electrical work is a minor addition or a separate job that changes the total cost.
The Mini-split Parts a Contractor Sizes and Places
The indoor air handler mounts high on an interior wall of the room being served, which is where a homeowner notices it first. It delivers conditioned air directly into that space. The outdoor unit sits on the ground or a wall bracket outside the house and houses the compressor and the other components that make the system run.
A refrigerant line set runs through a small opening in the wall to connect the two units, carrying the working fluid between them. A condensate drain line also exits the indoor unit and routes moisture outside. The electrical disconnect and dedicated circuit tie into both units at the outdoor side.
The drawing shows a typical layout, and a licensed contractor determines exactly where each piece is placed in your house based on its structure and your needs.
