Takes about a minute. No obligation.
A contractor diagnosing a central AC repair in Botetourt County has to separate what weather has put on the equipment from what time and workmanship have. 123 severe weather events were recorded in Botetourt County, Virginia between 2015 and 2024. At that rate, severe weather is real but not relentless, and it does not explain most of what contractors find when they open a system. A compressor that has given out, a capacitor that has failed, refrigerant that is low: in most cases the contractor's findings point to wear and installation quality before they point to storm load.
Refrigerant lines corrode, contactors pit, and capacitors lose tolerance over years of summer load. Half the homes in Botetourt County, Virginia were built in 1984 or earlier (2020-2024 ACS 5-year). A system that has been running in a house since well before recent equipment generations may take parts that manufacturers have discontinued or moved to limited distribution, which means a repair quote can shift once the unit is open and the contractor sees exactly what model and revision is inside. The age on the house does not tell a homeowner that, but the opened cabinet does.
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. The compressor is where most repair calls begin. When it fails, the system runs but produces no cooling; when the condenser coil is blocked or damaged, the unit overheats and shuts down.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is a common source of trouble, freezing over when airflow is restricted or refrigerant is low. The blower motor and the refrigerant lines connecting the two units are also points a contractor examines early.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what work is needed in your specific home.

What happens once a contractor comes out
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.
