Takes about a minute. No obligation.
Sizing a mini-split in Crawford County starts with the house, not a weather assumption. 71 severe weather events were recorded in Crawford County, Wisconsin between 2015 and 2024. At that rate, severe weather shows up often enough to belong in the picture but rarely enough that it does not define how hard the system runs day to day. A contractor here spends more time on manual load calculations, wall construction, window exposure, and how the zones are drawn than on hardening the install against constant weather stress. Get the sizing wrong and the equipment cycles poorly no matter what the sky does.
Electrical panels in Crawford County houses were not built to anticipate what a mini-split draws today. Half the homes in Crawford County, Wisconsin were built in 1978 or earlier (2020-2024 ACS 5-year). A house built that long ago was wired for the loads of its time, and those loads were different. When a licensed contractor comes to quote a ductless installation, the panel is where the job either proceeds or stalls, because undersized service has to be addressed before the new unit can run safely. Ductwork is not the variable here; mini-splits do not need it. What the electrical can carry is.
What a Mini-split Installation Covers
The indoor air handler mounts high on an interior wall in the room being conditioned, and it is the piece a homeowner sees every day. The outdoor unit sits on the ground or a pad outside the house and holds the compressor and condenser coil, which do the heavy mechanical work of the 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 from the indoor handler to the outside. A dedicated electrical circuit feeds the outdoor unit, and a control wire runs alongside the line set to carry signals between the two.
The drawing shows a typical layout, and a licensed contractor determines exactly how these pieces fit the conditions of your specific home.
