Takes about a minute. No obligation.
A contractor called out to repair a central AC unit in Lubbock County has to account for what the equipment has already been running against. 260 severe weather events were recorded in Lubbock County, Texas between 2015 and 2024. At that rate, severe weather is part of normal operating life for every system in the county, and components that carry the hardest load, compressors and capacitors chief among them, show wear that reflects it. A repair quote here starts with those parts, not with the easy checks.
Half the homes in Lubbock County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). Central AC systems installed in houses built around that period have had a long time to accumulate wear in the compressor, the capacitors, and the refrigerant lines, and the service manuals those units were built to are not what a parts supplier keeps on the shelf. A contractor who opens a system in a house from that era will price the job partly on whether the components it takes can still be sourced, and sometimes the answer changes what the repair looks like.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets shed to the outside air. The compressor lives inside that cabinet and is often where a contractor starts when the system stops cooling. The condenser coil and its fan work alongside it, and a fault in any of those parts shows up fast.
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 refrigerant line set runs between the two units connecting the indoor and outdoor sides. The thermostat on the wall ties the whole system together and is one of the first things a contractor checks before opening anything up.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what needs attention in your specific home.

What the repair visit looks like
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.
