A contractor diagnosing a central AC repair in Travis County starts by establishing what the system has been running against, because the answer changes which parts get inspected and in what order. 277 severe weather events were recorded in Travis County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and compressor wear, capacitor fatigue, and refrigerant stress all accumulate against that load over the life of a system. A part that tests borderline on the bench may have been borderline for longer than the homeowner knows.
Half the homes in Travis County, Texas were built in 1999 or earlier (2020-2024 ACS 5-year). A house built by then has almost certainly seen at least one complete equipment turnover since it was first cooled. The system running in it today was chosen and dropped in well after the original build, which means the contractor opening it is working with parts whose production run may have already ended. When a unit fails, what takes time and money is sourcing what that specific system actually takes, not the labor of pulling and replacing it.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the condenser coil, the compressor, and the fan that pushes air across them. When a system stops cooling, these are the first places a contractor looks. A failed compressor or a dirty condenser coil can each kill cooling entirely.
Inside, the air handler holds the evaporator coil and the blower that pulls warm household air across it. The refrigerant line set runs between the two units, and the expansion valve sits where that line meets the evaporator coil. A leak in the line, a frozen coil, or a failing blower motor all show up at these points.
The drawing shows the typical layout of these components, and a licensed contractor determines exactly what applies to the system in your house.

What HVAC Repair Looks Like in Travis 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 Rules for HVAC Repair in Travis 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 Travis County
Extreme weather puts real load on cooling equipment, and the pattern of storms in a given area shapes how hard a system works and what tends to fail. Repair needs here are tied directly to local conditions, which is why the weather record for this area belongs on a page about Central AC service.
