Step 1 of 3: Equipment
A two-story house with beige horizontal siding, a covered front porch, and a dark shingled roof, set behind a lawn with shrubs, leafy trees on both sides, and a wet street in the foreground.

Sizing a mini-split here is a heating problem, full stop. Homes in Fremont County, WY have essentially no cooling season — no month of the year is warm enough to call for it. A contractor quoting an install has no cooling load to calculate, which means every decision about capacity, refrigerant line length, and outdoor unit placement is driven by how well the system moves heat into the house on the coldest days of the year. The compressor's cooling-side duty is absent, so the heat exchanger and the coil carry the whole of what the unit is asked to do.

Older electrical panels in this county's housing stock are often the variable a contractor has to settle before anything else gets priced. Half the homes in Fremont County, Wyoming were built in 1978 or earlier (2020-2024 ACS 5-year). Wiring sized for the equipment of that era was not built to carry what a mini-split outdoor unit and its air handlers pull, and a contractor quoting the job has to look at the service panel and the branch circuits before the equipment selection means anything. If the panel needs an upgrade, that cost belongs in the scope from the start.

What a Mini-split Installation Covers in Your Home

The indoor air handler mounts high on a wall inside the room being served, and it is the piece a homeowner sees every day. The outdoor condenser unit sits on the ground or a wall bracket outside, housing the compressor and the components that drive the whole system.

A refrigerant line set runs through a small hole in the wall to connect the two units, and a condensate drain line carries moisture out of the building. The outdoor unit also requires a dedicated disconnect box mounted nearby, which a contractor fits as part of the installation.

The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your house.
