A contractor repairing a mini-split in Bexar County works out what the system has already been through before settling on a cause. 387 severe weather events were recorded in Bexar County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition for equipment here, and compressor strain, refrigerant stress, and capacitor fatigue show up in repair calls as the product of repeated load over time. A failed part does not always point to one bad season. It often points to a system that has been running hard for years against a climate that does not let up much.
Mini-split systems installed in houses built around the median for this county have years of Texas heat and humidity behind them, and what a contractor finds when the unit comes open is often a refrigerant circuit or control board that takes parts no longer stocked at the nearest distributor. Half the homes in Bexar County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A repair on equipment that age does not stall on labor or access. It stalls on the supply chain, and a contractor who has not checked parts availability before quoting a scope can price the job twice.
The Parts of a Mini-split a Contractor Checks First
The indoor air handler mounts high on an interior wall and pushes conditioned air directly into the room. Its fan, coil, and filter are the first things a contractor examines, because a dirty coil or a failed fan motor will show up in the air output before anything else does. Refrigerant leaks often start here too.
The outdoor condenser unit sits on a pad or bracket outside the house and holds the compressor, the second coil, and the fan that rejects heat to the outside air. Running between the two units, the refrigerant line set and the condensate drain are checked for blockages, crimps, and leaks that can quietly undermine either unit.
The drawing shows a typical mini-split layout, and a licensed contractor determines which components are the source of the problem in your specific home.

Severe Weather Events in Bexar County
Bexar County weather puts real load on mini-split systems, and load is what drives repairs. How hard the climate pushes the equipment shapes how often a unit needs attention and what kind.
