A contractor called out to repair a central AC system in Radford city spends most of their diagnostic time on the equipment itself: how old the compressor is, whether the refrigerant was ever checked, how the coils and capacitor have held up across years of summer use. 34 severe weather events were recorded in Radford city, Virginia between 2015 and 2024. At that rate, severe weather lands here as an occasional pressure on a system rather than a grinding, cumulative one. A contractor who blames storm load on a failed contactor or a seized blower motor is skipping past the more likely answer, which is deferred maintenance or a component that simply ran its course.
Ductwork in houses built for earlier systems accumulates decades of particulate, joint separation, and liner degradation that shows up the moment a contractor opens the system for a repair. Half the homes in Radford city, Virginia were built in 1976 or earlier (2020-2024 ACS 5-year). A unit running in stock like this may have been replaced once or twice since the house went up, which means the refrigerant type, the control board, and the contactors inside it could belong to any of several generations of equipment. When a contractor pulls a failed component, the question is whether that part is still in production or has to be sourced from salvage.
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. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet accounts for a large share of the calls that end in no cooling.
Inside, the air handler or furnace cabinet sits in a utility closet, basement, or attic and holds the evaporator coil and blower. The evaporator coil is a common failure point when the system freezes up or drains poorly. The blower motor and the metering device that meters refrigerant into that coil are also pieces a contractor will inspect when airflow or cooling is off.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what condition they are in for the specific house.

What HVAC Repair Looks Like in Radford
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.
