Takes about a minute. No obligation.
A central AC system in Richmond County has not been sitting in mild air. 97 severe weather events were recorded in Richmond County, Virginia between 2015 and 2024. At that rate, compressors, capacitors, and condenser coils carry a real and ongoing workload, and a contractor repairing a system here checks those components for wear that builds from repeated stress, not just from a single bad event. What they find shapes both the repair and what they flag for the homeowner about the rest of the system.
Ductwork installed for one generation of equipment and now carrying another is what a contractor opens up to in much of Richmond County. Half the homes in Richmond County, Virginia were built in 1978 or earlier (2020-2024 ACS 5-year). That gap means parts availability is a real variable on repair calls here: a system running in a house that old has likely had components swapped more than once, and what is inside when the unit comes open may not match what the nameplate suggests. A contractor has to confirm what is actually in the system before pricing the repair.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits on a concrete pad beside the house and is usually the first place a contractor looks when something goes wrong. Inside it, the compressor pressurizes the refrigerant and the condenser coil releases heat. If the system runs but blows warm air, or trips repeatedly, either of those components is often where the fault traces back.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil absorbs heat from the indoor air, and the blower pushes that air through the system. A refrigerant line set connects the two units, and the expansion valve and the contactor are smaller components that contractors examine closely because failures there can mimic problems elsewhere.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific house and what each one needs.

What HVAC Repair Looks Like in Richmond 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.

Severe Weather Events in Richmond County, Year by Year
Extreme weather puts stress on cooling equipment in ways that show up later as repair calls. Knowing the pattern of weather events in this area is part of understanding why AC systems here wear the way they do.
