Takes about a minute. No obligation.
A mini-split in this area is, functionally, a heating system. Homes in Teton County, WY have essentially no cooling season — no month of the year is warm enough to call for it. The compressor runs through cold months to move heat into the house, and the defrost cycle works against ice buildup on the outdoor coil. Those are the components a contractor has to get right at installation, because an undersized unit or a poorly chosen cold-weather refrigerant spec will show up as lost capacity on the first hard day. Sizing the indoor head count and placing the outdoor unit where defrost drainage can clear are not afterthoughts.
Electrical panels in much of this county's housing were sized for loads that predate the equipment a mini-split contractor is now asked to run on them. Half the homes in Teton County, Wyoming were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor quoting a mini-split installation has to pull the panel before pricing the job, because what looked adequate for the original equipment often falls short for a new system's demand. The ductwork question is easier here: mini-splits don't use it. The panel is where the answer lives.
What a Mini-split Installation Covers in Your Home
The indoor air handler mounts high on a wall inside the room being conditioned, where it draws in room air and delivers treated air back out. The outdoor unit sits on a pad or bracket outside the house and holds the compressor and condenser coil, doing the mechanical work of the system.
A refrigerant line set runs through a small penetration in the wall to connect the two units, and a condensate drain line carries moisture from the indoor unit to the outside. A dedicated electrical disconnect is placed near the outdoor unit to give a contractor safe access to power.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.
