Takes about a minute. No obligation.
A contractor quoting a mini-split installation in St. Martin Parish has to establish the load before anything else, because an undersized system loses ground slowly and then all at once. Homes in St. Martin Parish, LA run cooling about six months a year, from May through October. The compressor and condenser fan are the components that pay the price, starting and stopping through every one of those months. A unit installed with the wrong capacity or a sloppy refrigerant charge will show the deficiency well before the equipment might otherwise warrant attention, simply because the idle time that could mask a marginal install does not exist here.
Electrical service is where a mini-split installation in St. Martin Parish gets settled. Half the homes in St. Martin Parish, Louisiana were built in 1986 or earlier (2020-2024 ACS 5-year). Houses built through that period were wired for the equipment of that moment, and the panels put in then were sized accordingly. A mini-split draws a different load profile, and a contractor has to establish what the existing service will carry before any equipment gets ordered. What the panel shows determines whether the install is straightforward or whether the electrical work runs ahead of it.
The Mini-split Components a Contractor Sizes and Places
The indoor air handler mounts high on an interior wall inside the room being conditioned, and it is the piece a homeowner sees every day. The outdoor condenser unit sits outside the house, usually on a pad or bracket at ground level or along an exterior wall, and it carries the compressor and the fan that shed heat to the open air.
A conduit bundle runs through a small penetration in the wall to connect the two units, carrying the refrigerant lines, the power cable, and the condensate drain line together. Some installations add a second or third indoor head connected to the same outdoor unit, each one placed in a different room and wired back through its own line set.
The drawing shows a typical layout, and a licensed contractor determines what fits the specific structure, wall placement, and room configuration of your home.
