A contractor quoting a central AC installation in Southampton County works out what the building actually demands before settling on equipment size, and the local weather record is a small part of that calculation. 78 severe weather events were recorded in Southampton County, Virginia between 2015 and 2024. At that rate, severe weather is an occasional event in this area, present but not the dominant pressure on a system's operating life. Duct layout, insulation quality, and the age of the structure carry more weight in the sizing decision than storm history does. A contractor who gets those wrong produces an undersized or oversized system regardless of how mild the seasons run.
Older ductwork routed for the equipment of its era is what a contractor opening up a Southampton County house finds standing between a clean install and a complicated one. Half the homes in Southampton County, Virginia were built in 1981 or earlier (2020-2024 ACS 5-year). That gap between what the house was built to carry and what a new central AC unit draws is where the real scoping work happens. A contractor has to trace what is already in the walls, check whether those runs have the capacity and condition a modern system needs, and price accordingly. The electrical panel gets the same look, for the same reason.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. Inside, the air handler or furnace with an evaporator coil sits in a utility closet, attic, or basement. These two units are the core of what a contractor brings in and sets into place.
A refrigerant line set runs between the indoor and outdoor units, connecting them through the wall or floor. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A contractor also installs the condensate drain line, which carries moisture from the indoor coil to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits into your home.

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.
