Takes about a minute. No obligation.
A central AC unit called in for repair here has been running against real weather pressure for years, and a contractor has to sort out how much of that load the system has been carrying before they can say what failed and what it costs to fix. 94 severe weather events were recorded in Galveston County, Texas between 2015 and 2024. At roughly the national midpoint for severe weather, this county puts a steady, unremarkable-looking burden on compressors, capacitors, and contactors that quietly shortens the window before those parts give out. A failed capacitor here is not automatically storm damage, but the cumulative load of seasons like these is what a contractor weighs when they pull the cover and see what is actually worn.
Ductwork and electrical in a house this old were put in for equipment that has since been replaced at least once, so what a contractor opens at the service call carries its own separate history. Half the homes in Galveston County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A system that has been recharged, patched, or had components swapped over the years can fail in ways that a visual check of the cabinet will not show. The contractor has to read what the compressor, the capacitor, and the coil actually look like inside, and whether the parts that system takes are still in supply, before the repair scope becomes clear.
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 condenser coil. These are the components a contractor reaches first when a system stops cooling, because a failed compressor or a clogged or leaking coil accounts for a large share of Central AC breakdowns. The air handler or furnace cabinet lives inside, typically in a utility closet, attic, or basement, and it circulates air across the evaporator coil.
The evaporator coil sits inside that air handler cabinet, and a frozen coil or a refrigerant leak there will shut down cooling just as completely as a failed outdoor component. The refrigerant lines run between the two units, and the thermostat on the wall ties all of it together by telling the system when to run. A contractor traces the fault from the thermostat signal outward through both units.
The drawing shows the general layout of a Central AC system, and a licensed contractor determines which components apply to your specific house and situation.

What HVAC Repair Looks Like in Galveston 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 Galveston 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 Galveston County
Coastal heat and storm activity put real strain on central AC equipment over time. How hard a system has to work, and how often it gets pushed past normal operating conditions, shapes what kinds of repairs come up and how soon.
