Sizing a mini-split for a Hempstead County home is not a catalog decision. Homes in Hempstead County, AR run cooling about five months a year, from May through September. The compressor and condenser fan spend a long stretch of every year starting and stopping, and the wear from that accumulates on whatever the installer left behind: a refrigerant charge that is slightly off, a mounting surface that flexes, a line set with too tight a bend. A contractor quoting this job has to run a room-by-room load calculation first, because an undersized unit runs longer cycles than a correctly sized one, and a correctly sized unit installed poorly behaves the same way.
Electrical panels in much of this county's housing were built for a load that predates modern ductless equipment by a significant margin. Half the homes in Hempstead County, Arkansas were built in 1979 or earlier (2020-2024 ACS 5-year). A mini-split draw can exceed what those original panels were rated to handle, so the panel assessment comes before the equipment selection, not after. A contractor who skips that step is quoting blind.
The Mini-split System a Contractor Installs
The indoor air handler mounts high on an interior wall, inside the room being conditioned. It is the piece the homeowner sees every day. The outdoor condenser unit sits on a pad or bracket outside the house and houses the compressor and the hardware that drives the whole system.
A set of refrigerant lines and a condensate drain line run through a small opening in the wall, connecting the two units. A disconnect box goes on the exterior wall near the outdoor unit, giving the contractor a safe shutoff point close to the equipment.
The drawing shows a typical layout, and a licensed contractor determines exactly how the equipment is positioned and connected in your home.
