A contractor called out to repair a central AC unit in San Jacinto County is not walking into a system worn down by relentless weather. 26 severe weather events were recorded in San Jacinto County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, and it does not account for the compressor that has run hot for years or the capacitor that was borderline at the last service. What a contractor finds in failed components here traces back to equipment age and how the system was maintained, not to weather load. That is where the diagnosis starts.
Ductwork and wiring put in decades before current equipment was installed tend to stay in place, so what a contractor finds once the unit is open carries more weight than the building's age on its own. Half the homes in San Jacinto County, Texas were built in 1991 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and when current systems were installed means the equipment a contractor opens often predates the parts supply a straightforward repair would assume. If a compressor or coil turns out to take components no longer in regular production, the job changes scope before the quote is final.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it is where the system sheds the heat it has pulled from your air. The indoor air handler or furnace cabinet stands inside, most often in a utility closet, attic, or basement, and it pushes cooled air through the home. These two units are the first places a contractor looks when a system stops cooling or stops running altogether.
The copper refrigerant lines run between those two units, carrying the working fluid that makes the whole cycle possible. Alongside those lines, the condensate drain and drain pan sit beneath the indoor unit to carry away the moisture the system pulls from your air, and the thermostat mounted on a main-floor wall is the control point that tells the system when to run and when to stop. A fault in any of these can produce symptoms that look like a failed compressor or a refrigerant problem, so a contractor works through them as part of the same diagnosis.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific home.

What HVAC Repair Looks Like in San Jacinto 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.
