A contractor called out to repair a central AC in Manassas is not going to pin a failed component on what the sky has done. 15 severe weather events were recorded in Manassas city, Virginia between 2015 and 2024. At that rate, severe weather is an event here, not a condition, and most systems have spent their working lives without much of it. Age, the quality of the original installation, and how consistently the unit was serviced are what wear a compressor or a contactor down in this area. A contractor will look there first, and that is where the answer is.
Half the homes in Manassas city, Virginia were built in 1985 or earlier (2020-2024 ACS 5-year). A house built in that era was not wired or ducted for the equipment running in it now. When a repair opens a system here, the condition of the surrounding ductwork and the connections feeding the unit are part of what determines whether a single part swap closes the job or whether corroded wiring or a compromised duct joint is driving the failure. A contractor who pressure-tests only the equipment and leaves those connections unchecked can close a call that opens again in weeks.
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 sheds the heat that has been pulled from indoors. The indoor air handler or furnace cabinet lives in a basement, attic, or utility closet and pushes conditioned air through the home. When a system stops cooling, the condenser and the air handler are where a contractor starts.
The copper refrigerant lines run between those two units, carrying the fluid that makes the whole exchange possible. Alongside the air handler sits the evaporator coil, a finned assembly that does the actual work of pulling heat from indoor air. The condensate drain line and the electrical disconnect at the outdoor unit round out what a contractor traces when chasing a fault.
The drawing shows a representative layout, and a licensed contractor determines what applies to this particular house and system.
