A contractor pulling a central AC unit in Hays County has to sort out what the system has been running against before they can say what gave out. 108 severe weather events were recorded in Hays County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition here, and the wear a contractor finds on capacitors, contactors, and coils reflects a system that has been working hard through it. Age and maintenance history still matter, but a diagnosis that ignores the load this climate puts on cooling equipment will miss the reason a part failed and price the repair wrong.
Recent housing stock carries equipment that was matched to it from the start, which changes what a repair call is actually about. Half the homes in Hays County, Texas were built in 2007 or earlier (2020-2024 ACS 5-year). A system in a house of that age was installed into infrastructure sized for it, so when something fails, the opened unit is where the answer lives: a worn capacitor, a failing contactor, a refrigerant problem. The parts those systems take are still in production. A contractor is not working around mismatched ductwork or chasing a component that has been out of manufacture for years.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside or behind it, and it is where heat gets released to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor examines when a system stops cooling. A failed compressor, a refrigerant leak at the condenser coil, or a burned-out condenser fan motor each produce their own pattern of symptoms.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, the blower motor, and the expansion valve, all of which a contractor will inspect when the outdoor unit checks out fine. The refrigerant lines run between the two cabinets, and the thermostat sits on an interior wall controlling the whole system. A wiring fault at the thermostat or a blockage at the expansion valve can shut a system down just as completely as a compressor problem.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in Hays County
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
Licensing and Legal Requirements in Hays County, Texas
In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather Events in Hays County
Weather puts a measurable load on central AC equipment, and that load is local. What the climate does in Hays County shapes how hard the system works and what parts wear first.
