A mini-split quote in Lee County starts with what the house actually needs, not with a catalog spec pulled from a national chart. 46 severe weather events were recorded in Lee County, Texas between 2015 and 2024. At that rate, severe weather is a real but infrequent pressure on equipment, which means a contractor installing a new system has to get the sizing and refrigerant line work right from the start. A unit undersized or poorly mounted will underperform long before the weather becomes the explanation.
Electrical service sized for an earlier generation of residential loads is what a contractor finds behind the walls of a typical house here. Half the homes in Lee County, Texas were built in 1992 or earlier (2020-2024 ACS 5-year). Mini-split systems draw differently than what many of these houses were wired to handle, and the panel is where that gap shows up before anything else. Ductwork is not a factor with mini-splits, so the electrical is where the question of scope gets settled.
The Parts of a Mini-Split System and Where Each One Goes
The indoor air handler mounts high on an interior wall inside the room being conditioned, where it draws in room air and delivers conditioned air back out. The outdoor unit sits on the ground or a bracket on an exterior wall and houses the compressor and condenser coil, doing the heavy mechanical work of the system.
A set of refrigerant lines runs through a small opening in the wall to connect the two units, carrying refrigerant back and forth between them. A condensate drain line also exits the indoor unit, routing moisture out of the house, and a dedicated electrical circuit feeds the outdoor unit 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.

Severe Weather Events in Lee County
Weather puts a measurable load on heating and cooling equipment, and that load is a local fact. A mini-split sized and installed for what Lee County actually delivers will hold up differently than one spec'd for somewhere else.
