A contractor quoting a central AC installation in Webb County has to account for what drove the old system out before they size the new one. 84 severe weather events were recorded in Webb County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here, not a steady operating condition, so a compressor that gave out or ductwork that underperformed was most likely undone by years of use, a poor original install, or deferred maintenance. A contractor sizing a replacement unit works from the house's actual load requirements and the quality of what is already in the walls, because those are what decide how the new system runs.
Ductwork laid into a house decades before current AC equipment existed was sized and routed for a different system entirely. Half the homes in Webb County, Texas were built in 1997 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in stock like this opens walls and crawlspaces to find out whether what is already there can carry a modern unit's airflow, or whether it has to be modified before the new equipment goes in. The electrical panel gets the same look, since what a current system draws may exceed what the original service was set up to handle. Those two variables, duct capacity and electrical service, are what set the scope and the price of the job.
What a Central AC System Includes
The indoor air handler sits inside the house, most often in a utility closet, attic, or basement, and it pulls warm air across a coil to cool it before pushing it back through the home. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the coil that releases heat outside.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through copper tubing. A thermostat on an interior wall ties the whole system together, reading the indoor temperature and telling the equipment when to run.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific home.

What the Installation Actually Looks Like
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 Webb 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 Webb County
Extreme weather puts a measurable load on cooling equipment, and that load is not the same everywhere. What the sky does in Webb County shapes how hard a central AC system has to work and what it needs to hold up over time.
