A repair call on a central AC unit in San Patricio County asks a contractor to sort out what the system has been carrying before settling on a cause. 49 severe weather events were recorded in San Patricio County, Texas between 2015 and 2024. At that rate, severe weather is an occasional pressure on equipment here, not a relentless one, so a compressor that has given out is more likely worn from age or a poor original install than from weather load alone. Refrigerant lines, capacitors, and contactors each show wear in ways that point to one cause or another, and a contractor has to read those signs rather than assume the weather explains the bill.

Ductwork and electrical connections in a house this old were put in for whatever ran then, not for the system a contractor is opening today. Half the homes in San Patricio County, Texas were built in 1982 or earlier (2020-2024 ACS 5-year). That gap shows up inside the equipment as adapted fittings, spliced wiring, and drain paths that have been rerouted at least once. A contractor repairing a central AC unit here checks those upstream connections before pricing the job, because a failed capacitor or a leaking coil can be straightforward to address while the refrigerant lines feeding it are corroded at a junction nobody has touched in years.
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 holds the compressor and the condenser coil. These are the parts a contractor reaches first when a system stops cooling. A failed compressor or a coil that has lost its charge are common reasons a central AC quits.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil sits in the air stream above or below the air handler, and a frozen or fouled coil is a frequent culprit when airflow feels weak or cooling is uneven. The blower pushes conditioned air through the house, and a failing motor or capacitor shows up as reduced airflow or no air movement at all.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what work is needed in your specific home.

What Happens When the Contractor Comes Out
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.
