Takes about a minute. No obligation.
A contractor diagnosing a central AC failure in Gonzales County has to decide early what actually wore the system down. 31 severe weather events were recorded in Gonzales County, Texas between 2015 and 2024. At that rate, severe weather is a real but infrequent pressure on equipment here, not a grinding seasonal condition. A compressor that gives out in this county is more likely carrying years of deferred maintenance or a marginal install than it is absorbing storm punishment. That distinction changes what a contractor prices and replaces first.
Ductwork and wiring hold their age quietly, but opened equipment tells you something harder to work around. Half the homes in Gonzales County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). Systems installed into houses built that long ago have run through enough replacement cycles that a contractor pulling a failed part has to check availability before pricing the repair. If the component is discontinued or sourced only through specialty distributors, the job changes shape: the repair scope narrows or the cost of completing it climbs in ways the age of the house alone would never have suggested.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it carries the compressor and the condenser coil. These are the pieces a contractor goes to first when the system is running but not cooling, because a failed compressor or a fouled coil will stop the cooling before anything else does.
Inside the house, the air handler holds the evaporator coil and the blower. The air handler is usually in a closet, attic, or utility room, and the evaporator coil is where a refrigerant leak or an icing problem shows up. The refrigerant lines that run between the two units and the expansion valve that meters refrigerant flow are also on the checklist when the coil and compressor check out clean.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific house.

What HVAC Repair Looks Like in Gonzales 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.
