Takes about a minute. No obligation.
A contractor working a Central AC repair in Caswell County has to establish what actually failed and why before quoting any part of the job. 151 severe weather events were recorded in Caswell County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing condition here, and it accumulates on capacitors, contactors, and compressor windings over the life of a system. A contractor who skips that history risks replacing a part that will fail again for the same reason the first one did.
Ductwork in a house built for an earlier era of cooling collects decades of particulate, develops leaks at seams and joints, and runs in configurations that strain a system every time it cycles. Half the homes in Caswell County, North Carolina were built in 1981 or earlier (2020-2024 ACS 5-year). When a contractor opens a central AC unit here, what they find often reflects that history: a compressor or coil working harder than it should because the duct system feeding it has never been assessed. Parts availability matters too, because the equipment running in older stock is sometimes running on components that are no longer standard. The repair scope gets set by what the system actually contains, not by the initial complaint.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along the foundation, and it is where heat gets shed to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor examines when the system stops cooling. A failed compressor or a refrigerant leak at that unit accounts for a large share of repair calls.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air across it. The coil, the blower motor, and the capacitors that start each motor are all accessible from that cabinet and each is a common source of trouble. A clogged drain line runs from the coil to a floor drain, and a blocked line can shut the system down on its own.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply in this particular house.

What Happens When a 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.
