Takes about a minute. No obligation.
A contractor called out to repair a central AC system in Henry County has to do more than identify the failed part. 274 severe weather events were recorded in Henry County, Virginia between 2015 and 2024. At that rate of severe weather, components that absorb electrical and thermal stress, particularly the capacitor and contactor, accumulate wear that shows up as a failure somewhere downstream of the real cause. Replacing the part that quit without checking what drove it to failure leaves the next part in line to go the same way.
Ductwork in a house of this vintage was designed around equipment generations removed from what runs in it today. Joints shift, insulation degrades, and sealing that was never airtight loses what little integrity it had. Half the homes in Henry County, Virginia were built in 1974 or earlier (2020-2024 ACS 5-year). When a central AC system is underperforming and a contractor opens it up, the refrigerant circuit and the electrical connections get checked first, but in stock this old the duct system regularly turns out to be where the cooling is being lost. A repair that looks like a compressor problem can trace back to return air that the ducts are no longer delivering cleanly.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil. These are where a contractor starts when the system stops cooling. A failed compressor, a refrigerant leak at the coil, or a burned-out capacitor in that cabinet are among the first things a technician rules in or out.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. A frozen evaporator coil, a weak blower motor, or a clogged drain line each produce symptoms that point a contractor toward that part of the system. The thermostat, which mounts on a wall and tells the system when to run, is also checked early when the complaint is that the system does not respond.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

What HVAC Repair Looks Like in Henry County
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.
