Sizing a mini-split in Tangipahoa Parish is not a generic calculation a contractor can lift from a manual without measuring the house. Homes in Tangipahoa Parish, LA run cooling about six months a year, from May through October. A compressor that starts and stops through all those months accumulates wear on its contactor and refrigerant circuit in proportion to how well the original load calculation matched the actual demand. Undersized equipment runs longer cycles to chase the setpoint, and in a parish with a cooling season this extended, that gap in the original install shows up in the compressor long before it would somewhere the system sat idle half the year. A contractor quoting a new install here works out the load from the structure first, because the equipment will have little slack to absorb the error.
Electrical service is what a contractor prices around in much of this parish. Half the homes in Tangipahoa Parish, Louisiana were built in 1993 or earlier (2020-2024 ACS 5-year). A house built in that era was wired for whatever system the builder spec'd then, and the panel may not accept a modern mini-split circuit without an upgrade. The ductwork question falls away with a ductless unit, but the electrical does not, and a site visit that skips the panel is an incomplete quote.
The Mini-split Components a Contractor Works With
The indoor air handler mounts high on an interior wall in the room being served, pulling in room air and delivering conditioned air back out. The outdoor condenser unit sits on the ground or a wall bracket outside the house and holds the compressor and the coil that exchanges heat with the outside air.
A refrigerant line set runs between the two units, carrying the refrigerant that does the work between them. A condensate drain line also runs from the indoor unit to the outside, removing moisture the handler pulls from the air. The outdoor unit gets its own dedicated disconnect box mounted nearby.
