A contractor quoting a central AC repair in Orange County has to work out what the system has already been through before settling on a cause. 36 severe weather events were recorded in Orange County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of equipment life here, not an occasional disruption, and components like the compressor and condenser coils carry that load season after season. A failure that looks like simple age may trace back to years of hard running under repeated stress. The contractor checks both.
Older ductwork and aging equipment are a known pairing in this part of Texas. Half the homes in Orange County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). That means a large share of the central AC systems running here have been through enough service cycles that when something fails, the question a contractor has to answer first is whether the part the system takes is still in production. If it is not, the repair scope changes entirely. A system that would otherwise take a straightforward fix instead needs a decision about what to do next, and that decision depends on what the opened unit actually contains, not on the age stamped on the permit.
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 carries the compressor and the condenser coil. These are the pieces a contractor reaches first when a system stops cooling. A failed compressor or a fouled condenser coil is often where the problem ends up.
Inside, the air handler holds the evaporator coil and the blower. The evaporator coil sits in the air stream above the furnace or inside a dedicated cabinet, and the blower pushes conditioned air into the supply ducts. The refrigerant line set runs between the two units and is also part of what a contractor traces when something is off.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to your house and system.

What HVAC Repair Looks Like in Orange 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 Orange 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.
