A contractor quoting a mini-split installation in Midland County has to size for what the weather here actually demands, and that means the spec sheet from a manufacturer's chart is a starting point, not an answer. 264 severe weather events were recorded in Midland County, Texas between 2015 and 2024. At that rate of severe weather, a unit sized to the middle of the range for a given square footage will be pushed past its design load on a regular basis. What that produces is a compressor that cycles harder and longer than it was built to, which shortens the serviceable life of the equipment before maintenance or age have any say in it. The right size is determined by this county's load, not by the floor plan alone.
The electrical panel in a home from this era was designed around load assumptions that have since changed. Half the homes in Midland County, Texas were built in 1992 or earlier (2020-2024 ACS 5-year). A mini-split pulls dedicated circuits, and in housing stock this old, that panel has often never been updated to carry them. A contractor quoting an install here has to open the box and read what is actually there before the equipment conversation starts.
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 piece a homeowner sees every day. The outdoor condenser unit sits on a pad or brackets outside the house and holds the compressor and the fan that moves air across the coils.
A refrigerant line set runs through a small opening in the wall and connects the two units, carrying refrigerant between them. A condensate drain line runs from the indoor unit to the outside, clearing the moisture the air handler pulls from the room. A dedicated electrical circuit feeds the outdoor unit.
The drawing shows the standard layout of these components, and a licensed contractor determines exactly how they are positioned and routed in your home.
