A contractor called out to repair a central AC unit in Grimes County has to account for what actually wore the system down. 36 severe weather events were recorded in Grimes County, Texas between 2015 and 2024. At that rate, severe weather is an event in this county, not a steady condition the equipment has been fighting. A failed capacitor, a refrigerant leak, or a compressor that quit is far more likely to trace back to the age of the unit and how well it was maintained than to storm load. That is where a competent diagnosis starts.
Ductwork installed in a house does not get swapped out when the equipment gets replaced, which means the system a contractor opens today is running in infrastructure that was sized and sealed for something older. Half the homes in Grimes County, Texas were built in 1997 or earlier (2020-2024 ACS 5-year). When a repair calls for a specific capacitor, contactor, or control board, whether that part still ships is the question that decides how the job goes and what it costs. A contractor working through a repair here checks parts availability early, because a discontinued component turns a straightforward repair into a broader decision about the system.
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 holds the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling. The compressor is the most common source of a hard failure, and the condenser coil is where dirt and damage show up early.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil sits in the airstream above or beside that cabinet, and a frozen coil or a failing blower will stop cool air from reaching the rooms. The refrigerant lines run between the two units and carry the working fluid a contractor checks for leaks or low charge.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to your specific system and what work each one needs.

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.
