Takes about a minute. No obligation.
A contractor diagnosing a failed central AC unit in Buckingham County has to sort out what actually wore the system down. 136 severe weather events were recorded in Buckingham County, Virginia between 2015 and 2024. At that rate, severe weather is part of the operating picture here, but not so relentless that it accounts for every failure on its own. A compressor that gives out after years of service is more likely telling the story of its age and how well it was maintained than of any particular storm season. The contractor checks both, and the maintenance record usually speaks first.
Ductwork and compressors in houses this old have been running through repeated repair cycles, and the parts a system of this vintage takes are not always still manufactured. Half the homes in Buckingham County, Virginia were built in 1990 or earlier (2020-2024 ACS 5-year). When a unit opens up in a house built around that year, what a contractor finds often determines whether the job is a straightforward fix or a search for components that require sourcing time. Some parts come off the shelf. Others do not, and that gap is what sets the scope and the bill.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil. These are the parts a contractor reaches first when the system stops cooling, because faults here, whether a failed compressor, a refrigerant leak at the coil, or a seized fan motor, cut off the whole system at once.
Inside, the air handler or furnace cabinet houses the evaporator coil and the blower fan, usually in a closet, basement, or utility room. A clogged or iced evaporator coil, a failing blower motor, and a faulty expansion valve are common sources of problems that show up at the registers before a homeowner knows where to look.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what work is needed in your specific home.
