Sizing and refrigerant charge matter in any install, but in Atchison County the longer failure mode is dormancy. Homes in Atchison County, MO run cooling about three months a year, from June through August. A compressor that sat idle through fall, winter, and spring has to start hard on the first hot June day, and a system with a loose electrical connection or an undercharged line set will show it then, not gradually. Contractors quoting here set the charge precisely and verify the contactor and capacitor before they button the unit up, because those are the components a long off-season stresses at startup.
Electrical panels in this county's older stock were sized for loads that predate the equipment homeowners are running now. Half the homes in Atchison County, Missouri were built in 1957 or earlier (2020-2024 ACS 5-year). A contractor quoting a mini-split installation will open the panel and check what capacity is actually there before anything else gets scheduled, because a panel that cannot carry the new draw means an electrical upgrade comes first. The ductwork in houses of this vintage is a separate question, but for a mini-split the panel is where the job either proceeds or stops.
The Parts of a Mini-Split System Being Installed
The indoor air handler mounts high on an interior wall, inside the room being conditioned. It is the piece the homeowner sees and lives with every day. Outside the house, the outdoor condenser unit sits on a pad or bracket and does the mechanical work of the system.
A set of refrigerant lines runs through a small opening in the wall, connecting the two units and carrying the working fluid between them. A condensate drain line also exits the indoor unit, pulling moisture away from the room. A dedicated electrical line feeds the outdoor unit from the panel.
The drawing alongside shows a typical layout, and a licensed contractor determines exactly how each piece fits your home.

Heating and cooling equipment in Atchison County works against whatever the local climate puts out, and that workload is shaped by how hard the weather runs here. A mini-split sized and installed for local conditions holds up better than one spec'd for somewhere else.
