Sizing a mini-split for a Lee County home is not a generic calculation. The compressor starts and stops through a long cooling season with little time off, and every cycle adds to the mechanical history of the contactor and the refrigerant circuit. Homes in Lee County, AR run cooling about five months a year, from May through September. A contractor running a load calculation here has to account for a system that earns its wear steadily, which means getting the capacity right at installation protects the compressor from cycling harder than it was built to. An undersized unit running flat-out all summer will show that strain in the contactor and coil before an accurately sized one would.
Older electrical panels are sized for what the house originally ran, and a mini-split pulls a load that was not part of that original calculation. Half the homes in Lee County, Arkansas were built in 1973 or earlier (2020-2024 ACS 5-year). A contractor pricing a mini-split installation here checks the service panel before quoting the equipment, because an undersized panel means an upgrade comes first, and that changes the total scope of the job. The ductwork question does not apply to a ductless system, but the electrical one does, and it is not settled by a visual inspection from the driveway.
What a Mini-split Looks Like in Your Home
The indoor air handler mounts high on a wall inside the room you want conditioned. It is the piece a homeowner sees every day, and it is where conditioned air enters the living space. The outdoor unit sits on the ground or on a bracket outside the house and holds the compressor and the components that drive the whole system.
A refrigerant line set runs through a small opening in the wall to connect the two units, and a condensate drain line carries moisture from the indoor handler to the outside. A dedicated disconnect box is mounted near the outdoor unit to give the contractor a safe shutoff point for the equipment.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines exactly how each piece applies to your house.
