A contractor quoting a central AC installation in Brunswick County works from the building itself: its layout, its duct runs, how the previous system was sized and set in place. 54 severe weather events were recorded in Brunswick County, Virginia between 2015 and 2024. At that rate, severe weather is an occasional fact of life here rather than a standing condition, and it does not drive the install decisions the way it would in harder-hit areas. What drives them is whether the existing infrastructure can carry a properly sized system, and whether the last install was done right.
Existing ductwork is what a central AC installation in Brunswick County actually turns on. Half the homes in Brunswick County, Virginia were built in 1979 or earlier (2020-2024 ACS 5-year). Ducts laid in for older systems carry different load assumptions than what a new central unit delivers, and a contractor has to confirm whether the existing runs, returns, and insulation are up to the job before the new equipment is even priced. Electrical service gets the same look: a panel from that era often predates the draw a modern condenser requires, and some installations need that addressed first.
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, the two components that do the system's heaviest work. Inside, the air handler or furnace-and-coil assembly mounts in a utility space, basement, or attic and is where cooled air enters the duct system.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through an exterior wall. The thermostat goes on an interior wall where it reads the living space and signals the system to run or stop.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

What the Installation Actually Looks Like
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 Brunswick County
Local weather puts real demands on cooling equipment, and those demands vary by location. What Brunswick County sees in a given year shapes how hard a central AC system has to work and how well it needs to be sized for the job.
