A contractor diagnosing a failed central AC unit in Covington city starts with how the system has been maintained and how old its components are, because those factors carry more weight here than the weather. 31 severe weather events were recorded in Covington city, Virginia between 2015 and 2024. At that rate, severe weather is an event in this area, not a standing condition, and a compressor or capacitor that gives out is far more likely to show wear from years of normal seasonal cycling than from storm load. Deferred maintenance and aging refrigerant lines are what contractors find when they open these systems.
Ductwork in a house this old was put in for a system that no longer exists, and the equipment running in it now is itself a generation or two removed from what that ductwork was last sized for. Half the homes in Covington city, Virginia were built in 1951 or earlier (2020-2024 ACS 5-year). When a central AC unit fails in stock like this, a contractor opening the system is working out whether the failed component takes a part that is still manufactured, or whether the repair requires substitution, workaround, or a frank conversation about what comes next. That answer comes from what is in the unit, not from the year on the building permit.
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 or rear wall, and it carries the compressor and condenser coil. These are the pieces a contractor reaches first when a system stops cooling, because a failed compressor or a fouled coil will shut down the whole system. The air handler or furnace blower sits inside, typically in a basement, closet, or attic, and it pushes conditioned air through the house.
The evaporator coil sits directly above or below that indoor air handler, tucked inside the plenum where supply air first enters the duct system. The refrigerant lines run between the indoor and outdoor units, and the metering device that controls refrigerant flow sits at the evaporator end of those lines. A contractor also checks the condensate drain, which carries moisture pulled from indoor air to a floor drain or outside.
The drawing shows a representative layout, and a licensed contractor determines which components and access points apply to this particular house.

What HVAC Repair Looks Like in Covington
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.
