A contractor quoting a repair on central AC in Houston County has to sort out what actually wore the system down before settling on a scope. 77 severe weather events were recorded in Houston County, Texas between 2015 and 2024. At roughly that rate, severe weather lands here as an event, not a background condition every compressor has been grinding against for years. A unit that failed in this county probably failed because of age, a deferred refrigerant issue, or a capacitor that was overdue. Storm load is worth ruling out, but a contractor who leads with it is leading with the less likely explanation.
Half the homes in Houston County, Texas were built in 1981 or earlier (2020-2024 ACS 5-year). When a system opens up, what the contractor is working out is whether the parts it requires are still being made, or whether they have cycled out of standard production and have to be sourced elsewhere. That search changes both the timeline and the cost of a repair in ways that have nothing to do with the fault itself. A refrigerant valve on a system that has already been replaced once in a house this old may take a part that a supplier has to locate rather than pull from a shelf.
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 released to the air. Inside, the air handler or furnace cabinet holds the evaporator coil, which is the piece that pulls heat out of your indoor air. When either of those is the source of a problem, a contractor can usually tell quickly: a failing condenser may run but not cool, while a compromised evaporator coil often shows up as ice or a refrigerant issue.
The refrigerant lines run between the two units, carrying the charge that makes the whole exchange possible. The thermostat, mounted on an interior wall, is the control point, and the blower inside the air handler is what moves conditioned air into the duct system. Any one of those connections can be where a fault sits, so a contractor works through them alongside the main components.
The drawing shows the general layout of a central system, and a licensed contractor determines which parts and conditions apply to your specific house.

What HVAC Repair Looks Like in Houston 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.
