Takes about a minute. No obligation.
Size the indoor head wrong or leave the refrigerant charge short, and the compressor runs harder than it should on every cycle for the entire season. Homes in Evangeline Parish, LA run cooling about five months a year, from May through September. A contractor quoting a new system here has to do a real load calculation for each room the unit serves, not pull a number from the square footage alone. Refrigerant lines that were bent, kinked, or run too long at the original install restrict flow under that sustained demand. The compressor bears it first.
Electrical service panels in older Evangeline Parish homes were sized for the loads of the equipment that came with them, and a mini-split draws differently than what those panels were built around. Half the homes in Evangeline Parish, Louisiana were built in 1980 or earlier (2020-2024 ACS 5-year). That puts the panel, not the indoor or outdoor unit, at the center of what a contractor has to price first. If the existing service cannot carry the new load, the electrical work gets quoted alongside the install, not after it.
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 pushing 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 components that do the heavy work of the system.
A conduit bundle runs through a small opening in the wall, connecting the two units. It carries the refrigerant lines, the power cable, and the condensate drain line. The wall-mounted thermostat or wired controller sits inside the room and gives you direct control over each zone.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how the installation applies to your specific house and its existing conditions.

Severe Weather Events in Evangeline Parish
Extreme weather puts a sustained load on heating and cooling equipment, and Evangeline Parish sees the kind of climate swings that shorten equipment life when the system is undersized or poorly matched to the building. A mini-split sized and installed for local conditions handles that load differently than one spec'd for somewhere else.
