A contractor called out to repair a central AC unit in Comanche County has to account for what the equipment has already been through before settling on a cause. 358 severe weather events were recorded in Comanche County, Oklahoma between 2015 and 2024. At that rate, severe weather is part of the normal workload for every system in this county, not an occasional interruption to it. Capacitors, contactors, and compressor windings that show stress here may have reached that state under a heavier sustained load than a contractor would assume elsewhere, and the repair scope follows from which it is.
Ductwork in a house that has stood this long has likely carried more than one system through its life. The part a contractor pulls out matters less than whether it can be replaced. Half the homes in Comanche County, Oklahoma were built in 1977 or earlier (2020-2024 ACS 5-year). A system running in stock of this vintage may be old enough that certain components are no longer manufactured, which means a contractor opening the unit has to price availability, not just labor and the part itself. That changes what a repair costs and sometimes whether a repair makes sense at all.
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 carries the compressor and the condenser coil. These are the pieces a contractor reaches first when the system stops cooling. A failed compressor, a clogged coil, or a refrigerant leak all live here.
Inside, the air handler holds the evaporator coil and the blower. The air handler sits in a utility closet, attic, or basement and moves conditioned air into the duct system. The thermostat on the wall ties the two halves together and tells each one when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to the specific setup in your house.

What HVAC Repair Looks Like in Comanche 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.
