Takes about a minute. No obligation.
A central AC system in this county has been running against genuine weather pressure, and when it breaks down, a contractor has to untangle two separate causes before the repair scope is settled. 162 severe weather events were recorded in Armstrong County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition, not an occasional interruption, which means components like capacitors and contactors have been cycling hard. But wear from load looks a lot like wear from age, and a contractor who skips past that question can replace the wrong part. The diagnosis has to establish which failure drove the call.
Ductwork in a house this old has often been rerouted, spliced, or partly replaced by whoever serviced the system before, and the refrigerant lines and drain paths can tell a different story than the unit itself suggests. Half the homes in Armstrong County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). A contractor pulling the covers off a central AC system in stock like this finds components whose condition depends on that history of adaptation, not on any single installation date. The parts that need sourcing are the ones that dictate whether a repair closes in a day or stretches while a supplier searches.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it is where heat gets shed to the outside air. The indoor air handler or furnace coil assembly lives inside, typically in a closet, attic, or utility room, and it is the side of the system where cooled air enters your living space. Both units are the first places a contractor looks when something stops working right.
The refrigerant lines run between the two units and carry the charge that the system depends on; a leak anywhere along them will show up as weak cooling or ice on the coil. The thermostat on your wall is the system's control signal, and a faulty one can mimic problems that look like they belong deeper in the equipment. The contractor also checks the condensate drain, a small line that removes moisture pulled from the air, because a clog there can shut the system down.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for 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.
