A contractor quoting central AC installation in Giles County is solving for the house first: its square footage, its ductwork, the orientation of the structure. 79 severe weather events were recorded in Giles County, Virginia between 2015 and 2024. At that rate, severe weather is a real but occasional presence, not the dominant variable shaping what a system endures. A bad original install or an undersized unit will cost a homeowner more over time than the weather record here will. That is what a contractor has to price around.
Ductwork laid down for an older heating system was sized and routed for different airflow demands than a central AC unit will place on it. Half the homes in Giles County, Virginia were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor installing a new system has to assess whether those existing ducts will carry the load before any equipment gets priced, because if they will not, the duct work becomes part of the job. The electrical service is the same question: a panel that predates modern cooling may not have the capacity a new unit requires. What the house already holds decides the scope.
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-based evaporator coil sits in a utility space, basement, or closet and is the indoor half of the system. These two units are the core of what a contractor places and connects.
The refrigerant lines run between the outdoor and indoor units, and the thermostat goes on a central interior wall where it can read the home's air accurately. A condensate drain line also runs from the indoor coil to carry away moisture the system pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed in your specific home.

What the installation looks like from your side
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.
