Size a mini-split wrong in Iberia Parish and the compressor knows it before the homeowner does. Homes in Iberia Parish, LA run cooling about six months a year, from May through October. A unit that is undersized for that load starts and stops more than a correctly sized one, and each cycle adds wear to the compressor and the contactor. A contractor quoting an installation here has to run a proper load calculation first, because a number pulled from square footage alone will produce a system that runs short of capacity through the hottest part of the season and fails earlier because of it.
Older service panels were built around the load assumptions of the era they were wired in, and a mini-split draws differently from what most of that stock was originally built to serve. Half the homes in Iberia Parish, Louisiana were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here will check the panel before pricing anything else, because undersized service cannot simply be worked around. If the panel needs an upgrade, that becomes part of the job scope, and a quote that skips it will be wrong before the equipment ever arrives.
The Mini-split Components a Contractor Assesses for Installation
The indoor unit mounts high on an interior wall in the room being served, pulling in room air and delivering conditioned air back into the space. The outdoor unit sits on the ground or a bracket outside the home and houses the compressor and the components that move heat between inside and out.
A refrigerant line set runs through a small hole in the wall to connect the two units, carrying refrigerant between them. A condensate drain line runs from the indoor unit to move moisture out of the house, and a dedicated electrical line feeds the system from the panel.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed for your specific home.
