A contractor working a central AC repair in Harrisonburg has to settle, early in the diagnosis, whether a failed part gave out from use or from something external. 26 severe weather events were recorded in Harrisonburg city, Virginia between 2015 and 2024. At that rate, severe weather is a periodic fact of life here, present but not relentless, which means it seldom accounts fully for a blown capacitor or a struggling compressor. Wear from age and the quality of past service visits are what most repairs trace back to. A contractor who skips that audit and points at the weather is leaving the real cause unfound.
Half the homes in Harrisonburg city, Virginia were built in 1987 or earlier (2020-2024 ACS 5-year). For a central AC repair, that age of housing stock shapes what a contractor finds once the unit is open. Compressors, capacitors, and control boards from systems installed in older homes frequently belong to product lines that manufacturers have discontinued or revised, and a contractor has to verify parts availability before a repair quote means anything. The diagnostic visit and the parts search are two separate steps in housing like this.
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 holds the compressor and condenser coil. These are where a contractor starts when a system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor are the pieces that most often explain why a central AC has quit doing its job.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is a common source of ice buildup and refrigerant issues, and the blower motor is what a contractor checks when airflow has dropped. The expansion valve and the refrigerant lines connecting the two cabinets round out what the contractor traces when the outdoor unit alone does not tell the full story.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and equipment.

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.
