Takes about a minute. No obligation.
A contractor quoting a central AC repair in Falls Church has to decide what actually wore the system down. 26 severe weather events were recorded in Falls Church city, Virginia between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition, so it rarely accounts for a failed capacitor or a compressor that stopped holding pressure. What a contractor finds instead tends to trace back to how old the equipment is, how it was installed, and how consistently it has been serviced. Storm load is not the explanation to reach for first.
Half the homes in Falls Church city, Virginia were built in 1971 or earlier (2020-2024 ACS 5-year). A house that old has almost certainly seen more than one cooling system come and go, and the one running now may be wired into original low-voltage control wiring or connected to ductwork that was modified to fit a unit chosen decades later. When a repair technician opens the cabinet, what they find drives the job: a refrigerant circuit refitted to a different specification, control boards spliced into wiring they were not made for, or a compressor sitting in a modified cradle. Whether the parts that system takes are still in production is the question that sets the price and the timeline.
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 carries the compressor and the condenser coil. These are the pieces a contractor reaches first when a system stops cooling, because the compressor does the hardest mechanical work and the coil sheds heat directly to the outside air.
Inside, the air handler holds the evaporator coil and the blower fan, typically in a utility closet, basement, or attic. The refrigerant line set runs between the two units, and the thermostat on the wall ties the whole system together, telling it when to run and when to stop.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific house and equipment.

What HVAC Repair Looks Like in Falls Church
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.
