Sizing a mini-split for a Franklin County home is not a catalog decision. Homes in Franklin County, AR run cooling about four months a year, from June through September. A compressor that was matched to the wrong load calculation starts the season already working harder than it should, and the thermal stress accumulates across every cycle. By the time August arrives, an undersized unit is pulling longer runs to hold setpoint, which accelerates wear on the contactor and the coil. A contractor quoting this job has to calculate cooling load from the house itself, not from square footage alone.
Electrical panels in much of Franklin County's housing stock were sized for loads that predate modern equipment. Half the homes in Franklin County, Arkansas were built in 1985 or earlier (2020-2024 ACS 5-year). A mini-split installation puts new demands on whatever service is already in the house, and a contractor working here checks the panel early, because an undersized service changes the scope of the job before the unit is ever chosen. Ductwork is not a factor with a mini-split, but the electrical is, and older panels often require an upgrade before the install can proceed.
What a Mini-split Installation Covers in Your Home
The indoor air handler mounts high on a wall inside the room being served, pulling room air across its coil and delivering conditioned air back into the space. The outdoor unit sits on the ground or a bracket outside the house and holds the compressor and condenser coil, doing the heavier mechanical work of the system.
A refrigerant line set runs through a small opening in the wall to connect the two units, carrying refrigerant between them. A condensate drain line runs alongside it, carrying moisture out of the building, and a power cable ties the indoor and outdoor units together so they operate as one system.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your house.
