A contractor called out to repair a central AC system in Lavaca County has to work out what actually broke the equipment before quoting anything. 26 severe weather events were recorded in Lavaca County, Texas between 2015 and 2024. At that rate, severe weather is something a system here encounters now and then, not something it runs against season after season. A compressor that has given out, a capacitor that has failed, a refrigerant circuit that is low: in this county those findings trace back to component age or to how the system was installed, not to the weather loading it down. The repair scope follows from what the contractor opens up and what they find worn.
Ductwork and wiring aside, the variable that decides how a repair job goes in this county is parts availability. Half the homes in Lavaca County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). Equipment installed into houses of that age has been replaced, and replaced again, and what a contractor pulls out of the cabinet today may be a generation or two removed from what the house was built around. When a compressor or control board fails, the opened unit is the first real piece of information: what it actually is, what it actually takes, and whether that part is still in production. A repair that looks like an afternoon can stretch when the answer to that last question is no.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it carries the compressor and the condenser coil. These are the parts that take the heat pulled from inside and release it outdoors. When either one fails, the whole system stops moving heat, so a contractor goes here first.
Inside the house, the air handler holds the evaporator coil and the blower fan. The evaporator coil absorbs heat from the air passing over it, and the blower pushes that air through the house. The expansion valve and refrigerant lines connect the two units, and a fault in either can look like a coil problem or a compressor problem until a contractor traces the pressure through the system.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.

What HVAC Repair Looks Like in Lavaca 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 Lavaca County, Texas

Severe Weather Events in Lavaca County
Extreme weather puts real strain on cooling equipment, and how hard a system works over its life depends largely on what the local climate demands of it. Repair needs in Lavaca County are shaped by those same conditions, which is why local weather history belongs on this page.
