Takes about a minute. No obligation.
A contractor sizing a mini-split here has to get the load calculation right before anything else, because an undersized unit will start and stop more than it should across a long cooling season. Homes in West Feliciana Parish, LA run cooling about five months a year, from May through September. Compressors in this climate accumulate real wear on the contactor and the refrigerant circuit, and a unit that was undersized or improperly charged at installation reaches those limits faster than the homeowner expects. A sloppy install has less idle time to hide behind.
The electrical panel is where a mini-split installation either moves forward or stops. Half the homes in West Feliciana Parish, Louisiana were built in 1991 or earlier (2020-2024 ACS 5-year). Houses built by then were wired for the loads of that era, and the service panel a contractor finds on the wall today is often the original one. A mini-split draws differently from what those panels were sized to handle, so the first question on any quote here is whether the existing service can carry the new unit without an upgrade. The ductwork question does not apply, but the electrical one does, and it gets answered before anything else is priced.
The Mini-split Components a Contractor Works With
The indoor air handler mounts high on an interior wall, inside the room being conditioned, and delivers treated air directly into that space. The outdoor unit sits on a pad or bracket outside the house and houses the compressor and condenser coil. Together, these two units are the core of what a contractor accounts for when planning a mini-split installation.
A refrigerant line set runs through a small hole in the wall to connect the indoor and outdoor units, and a condensate drain line carries moisture from the air handler to the outside. A disconnect box is placed near the outdoor unit to allow safe electrical access. Each of these elements has a fixed location the contractor determines before work begins.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines what applies to your specific home and its conditions.
