Takes about a minute. No obligation.
A contractor called out to repair a central AC unit in Granville County has to settle one question early: what has actually worn this system down. 84 severe weather events were recorded in Granville County, North Carolina between 2015 and 2024. At that rate, severe weather is an event in this county, not a steady operating condition, so a compressor that has given out or a refrigerant line that has failed is pointing back at age, installation quality, or skipped maintenance rather than at cumulative storm load. The weather record here does not carry much weight as a diagnosis.
Ductwork and wiring aside, what decides a repair job in this county is what the opened unit actually contains and whether the components it takes are still in production. Half the homes in Granville County, North Carolina were built in 1992 or earlier (2020-2024 ACS 5-year). Systems installed into houses that old have been replaced, retrofitted, and replaced again, which means the unit a contractor opens today is not necessarily the generation you would predict from the building date. What it is determines whether parts are a same-week order or a sourcing problem, and that gap is where repair timelines actually live.
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 outside air. The compressor lives inside that cabinet and is often the first place a contractor looks when the system stops cooling. A failed capacitor or a seized compressor shows up fast.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is where the system pulls heat out of your indoor air. The refrigerant lines running between the two units and the expansion valve that controls refrigerant flow are checked when cooling is weak or the coil is freezing over. The blower motor and the contactor relay are also common points of failure a contractor will test early.
The drawing shows a representative layout, and a licensed contractor determines which components apply to your specific system and home.

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.
