Takes about a minute. No obligation.
A contractor diagnosing a failed central AC unit in Madison County works out what actually wore the system down before pricing a repair. 40 severe weather events were recorded in Madison County, Texas between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, which means the compressor that gave out on a July afternoon is far more likely carrying years of deferred maintenance or a slow refrigerant loss than the effects of storm load. A contractor checks refrigerant charge, capacitor condition, and coil state because those are what fail here. The weather record does not explain the bill.
Half the homes in Madison County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). A house that old has almost certainly worn out at least one full system already, which means the equipment running in it now is younger than the building by a wide margin. What that produces for a repair job is a unit whose internal condition reflects its own history, not the house's. Compressor wear, capacitor age, and refrigerant charge are what a contractor reads once the cabinet is open, and those findings set the repair scope. The permit year settles nothing about whether the parts a given system takes are still in production.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it carries the compressor and the condenser coil. Both are common failure points. A compressor that has seized or a coil that has fouled will stop the system from shedding heat, and a contractor will put eyes on both early.
Inside, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil sits in the airstream above or downstream of the blower, and a frozen coil or a failing blower motor will often be what explains warm air coming through the vents. The refrigerant lines that run between the two cabinets and the expansion valve that controls refrigerant flow are also on a contractor's check list.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific house and equipment.

What HVAC Repair Looks Like in Madison 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.
Licensing and Legal Requirements in Madison County, Texas
