A contractor quoting a mini-split installation in Galveston County starts with placement and mounting before anything else. 94 severe weather events were recorded in Galveston County, Texas between 2015 and 2024. At that rate of severe weather, an outdoor unit bracketed to a wall that can handle the load will outlast one that was sited for convenience. The refrigerant line routing, the conduit sealing, and the anchor hardware are all decisions the climate forces early in the job, and a contractor who knows this area prices for them from the start.
Ductless mini-split installation sidesteps the duct question entirely, but the electrical service in a house is a different matter. Half the homes in Galveston County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A panel that was sized decades ago for a smaller load may not carry what a new mini-split circuit draws, and a contractor has to open that assessment before a quote means anything. If the service needs an upgrade, that work comes first.
The Parts of a Mini-Split System and What Gets Installed
The indoor air handler mounts high on an interior wall, inside the room being conditioned. It is the unit a homeowner sees and interacts with daily. Outside, the condenser unit sits on the ground or on a wall bracket, handling the work the indoor unit depends on.
A refrigerant line set runs through a small opening in the wall, connecting the two units. A condensate drain line carries moisture away from the indoor unit, routed to a drain or to the exterior. A dedicated disconnect box goes in near the outdoor unit to give the condenser its own shutoff point.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines exactly how each piece applies to your house.
