Takes about a minute. No obligation.
A mini-split sized for an average load in a mild setting will run short of what this county actually demands. 100 severe weather events were recorded in Upshur County, Texas between 2015 and 2024. That rate of severe weather means outdoor units here cycle harder and longer than a manufacturer's standard assumptions allow for, and a contractor quoting a new install has to size around what the equipment will face in the field, not just what the square footage suggests on paper. Refrigerant line routing and mounting position matter too, because units set up without that local context get stressed in ways a straightforward spec sheet does not flag.
Electrical service is what decides how a mini-split installation goes in much of this county, and it gets settled before anything else on the job. Half the homes in Upshur County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). A house built around that time was wired for a different set of demands, and the panel a contractor finds may not carry what a modern inverter-driven unit draws. Ductwork is a separate question with mini-splits, since the system does not use it, but the electrical is real work that has to be scoped and priced on its own terms.
The Mini-split Parts That Come With an HVAC Installation
The indoor air handler mounts high on an interior wall in the room being served, and a licensed contractor positions it to reach the space evenly. The outdoor condenser unit sits outside the home on a pad or bracket, and it carries the compressor and the components that drive the whole system.
A refrigerant line set runs through a small penetration in the wall to connect the two units, bundled alongside a condensate drain line and the power and communication wiring. A wall-mounted thermostat or wired controller goes up inside the room to give the occupant direct control over that zone.
The drawing shows a standard layout, and a licensed contractor determines exactly how each piece fits this particular home.

Severe Weather Events in Upshur County
Upshur County's climate puts real demand on heating and cooling equipment, and that demand is shaped by how often the weather turns hard. A mini-split sized and installed for local conditions handles that load better than one that was not.
