A contractor quoting a central AC installation in Richmond County has to size the system for what this area actually throws at it, not for a best-case season. 97 severe weather events were recorded in Richmond County, Virginia between 2015 and 2024. That puts severe weather squarely in the range of a standing operating condition, not an edge case, which means duct layout, unit placement, and equipment capacity all have to account for a climate that pushes systems regularly. A contractor who treats this county as a mild-load environment will undersize the job.
Ductwork laid down for an older generation of equipment shapes what a central AC installation here actually involves. Half the homes in Richmond County, Virginia were built in 1978 or earlier (2020-2024 ACS 5-year). Ducts sized and routed for a different system can restrict airflow in ways that undercut a new unit before it runs its first cycle, and the electrical service feeding the house may have been designed around loads a modern condenser does not match. A contractor assessing a job in Richmond County opens the duct runs and checks the panel before the equipment choice means much.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which together shed heat collected from inside. The indoor air handler or furnace-mounted evaporator coil lives in a mechanical room, basement, or closet, and is the point where warm indoor air passes over refrigerant-filled coils and gives up its heat.
A copper refrigerant line set runs between the two units, carrying refrigerant back and forth through the walls or exterior of the house. The thermostat mounts on an interior wall and is the control point that tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.

What HVAC Installation 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
Weather puts a measurable load on cooling equipment, and that load varies by location. What happens in Richmond County shapes how hard a central AC system has to work and how well it needs to be sized and installed to hold up over time.
