A contractor quoting a central AC installation in Goliad County has to work out what the system will actually run against, and the answer here is that severe weather, while real, is not the dominant pressure on equipment. 37 severe weather events were recorded in Goliad County, Texas between 2015 and 2024. At that rate, most systems in this county spend the bulk of their lives in ordinary heat, not recovering from severe events. Poor sizing and loose duct work do more damage quietly than any storm. A contractor here earns their quote by getting the load calculation right for the house, not by speccing for a punishment the county's record does not reliably deliver.
Ductwork laid down for an older system carries assumptions about airflow, routing, and return placement that a new central AC unit may not share. Half the homes in Goliad County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing new equipment in a house from that era has to assess whether the existing duct layout will deliver air where the new system expects to push it, and whether the supply and return runs are sized for current equipment at all. If they are not, the duct work becomes its own scope of work, separate from the unit itself.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the mechanical heart of the system. Inside, the air handler or furnace cabinet stands in a utility space, closet, or attic and moves conditioned air through the home. Together these two units make up what a contractor installs.
The refrigerant line set runs between the outdoor and indoor units, carrying the working fluid that links the two sides of the system. A contractor also connects the thermostat, which sits on an interior wall and tells the system when to run, and the condensate drain line, which carries moisture pulled from the air out of the house.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What to Expect on Install Day
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.
What Goliad County, Texas Requires for HVAC Installation
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 Goliad County
Weather puts a load on cooling equipment, and that load is shaped by what the local climate actually does. A system sized and installed for conditions in Goliad County handles that reality differently than one spec'd somewhere else.
