Takes about a minute. No obligation.
A contractor called out to repair central AC in Highland County has to decide what actually wore the system down before they can price the job. 71 severe weather events were recorded in Highland County, Virginia between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, which means a compressor that has seized or a coil that has failed is almost certainly carrying the cost of years without service or a unit that was undersized from the start. The weather record is real, but it rarely lands as the explanation a repair contractor needs.
Ductwork and wiring age with the house, but the repair question in Highland County lands on the opened unit itself. Half the homes in Highland County, Virginia were built in 1971 or earlier (2020-2024 ACS 5-year). Systems installed into that stock over the decades since have turned over more than once, and what a contractor finds inside a failed unit here often includes components whose replacement parts are at the thin end of what manufacturers still supply. A capacitor or contactor is easy. A proprietary control board or a refrigerant circuit built around a discontinued spec sends the job in a different direction, one that changes both the timeline and what the contractor has to order before the work can close.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad against an exterior wall, and it carries the compressor and condenser coil. These are the parts a contractor reaches first when the system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor are the most common reasons the whole system goes down.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil is where refrigerant absorbs heat from the air moving across it, so a frozen coil or a clogged drain line shows up here. The blower pushes conditioned air into the duct system, and a weak or failed blower is a frequent cause of uneven cooling across the house.
The drawing shows a typical layout, and a licensed contractor will assess which components apply to your specific system and home.

What HVAC Repair Looks Like in Highland County
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.
