Takes about a minute. No obligation.
Before a contractor can tell you why your central AC failed, they have to work out what the system has been running against. 111 severe weather events were recorded in Lynn County, Texas between 2015 and 2024. At that rate, severe weather is a regular part of how equipment here ages, which means a refrigerant problem or a failing capacitor carries two possible histories: the system wore down under repeated stress, or it simply reached the end of its service life on its own schedule. A contractor has to pin that down because the answer changes the repair.
Ductwork and wiring in stock this old were put in for equipment that no longer exists, and what has built up inside them shapes every repair call. Half the homes in Lynn County, Texas were built in 1966 or earlier (2020-2024 ACS 5-year). A contractor opening a system in a house from that era finds electrical connections that have cycled through heat and cold long enough to corrode and loosen, refrigerant lines that have absorbed years of pressure fluctuation, and component wear that a visual inspection from the outside does not show. The repair scope is set by what the opened unit actually contains, not by the age written on the permit.
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 a system stops cooling. The compressor is the part that drives the whole cycle, and the condenser coil is where heat leaves the refrigerant.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the house. The refrigerant lines running between the two units and the expansion valve that meters refrigerant flow round out what a contractor traces when the problem is not immediately obvious.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific home.

What Happens When the Contractor Comes Out
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 Rules for HVAC Repair in Lynn County, Texas
In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather Events in Lynn County
Extreme weather puts real hours on AC equipment. The harder the system works to recover after each event, the more wear accumulates, and repair needs in Lynn County track closely with what the sky does here.
