A contractor called out to repair a central AC system in Meigs County works through the usual list first: how old the equipment is, how it was installed, and whether it has been serviced. 29 severe weather events were recorded in Meigs County, Tennessee between 2015 and 2024. At that rate, severe weather is an event here rather than a constant condition, so a compressor that has given out or a coil that is underperforming is far more likely to have gotten there through years of ordinary use than through storm load. A contractor will check refrigerant levels, inspect electrical connections, and look at how hard the system has been running, because wear from routine summer demand is what explains most of what they find.
Half the homes in Meigs County, Tennessee were built in 1994 or earlier (2020-2024 ACS 5-year). A house built that long ago has likely seen more than one cooling system come and go, which means the equipment a contractor opens today was installed into a structure that predates it by a significant margin. What that contractor finds inside matters more than the unit's rated age: refrigerant fittings that were adapted rather than replaced, wear on components that reflects actual running conditions rather than calendar years, and whether the parts the existing system takes are still in production. That is what determines the repair scope.
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 wall or behind the home. It holds the compressor and condenser coil, and when either is the problem, the system runs but cannot shed heat. The compressor is the piece contractors reach for first when cooling has stopped altogether.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil is where refrigerant absorbs heat from indoor air, and a frozen or dirty coil is a common reason a system blows air that never gets cold. The blower fan moves conditioned air into the supply ducts, and the refrigerant lines running between the two units carry the refrigerant that connects the whole system.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific home and situation.

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.

Severe Weather Events in Meigs County
Storm activity puts real stress on cooling equipment, forcing it to cycle hard, shut down unexpectedly, or run through conditions it was not rated for. How often that happens here shapes what a central AC system in Meigs County faces over its life, and what kind of repair work it is likely to need.
