A contractor quoting central AC installation in Campbell County has to treat the local weather record as part of the sizing problem, not background noise. 218 severe weather events were recorded in Campbell County, Virginia between 2015 and 2024. At that rate, the system a contractor specifies will spend its working life running against real load, not occasional load, and a unit sized to catalog minimums will be undersized for what this area actually asks of it. Capacity, refrigerant line quality, and the strength of the electrical connection all get priced to that reality from the start.
Ductwork laid down for an earlier system was sized for that system, and when a contractor fits a new central AC unit to it, the first question is whether the existing runs can move the air the new equipment produces without starving rooms or overloading the blower. Half the homes in Campbell County, Virginia were built in 1982 or earlier (2020-2024 ACS 5-year). That spread in age between the structure and the equipment running in it is where most of the installation variables live. Electrical service is the other one: panels installed well before current draw requirements were written into load tables get checked before anything is quoted.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and houses the compressor and condenser coil. Inside, the air handler or furnace-based evaporator coil sits in a utility space, basement, or attic, where it connects to the home's existing duct openings. These two pieces are the core of what a contractor brings and sets in place.
The refrigerant line set runs between the outdoor and indoor units, passing through a small penetration in the wall. A thermostat, mounted on an interior wall, is what the homeowner uses to control the whole system. Depending on the house, a condensate drain line also gets routed from the indoor unit to a suitable discharge point.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one applies to your house.

What HVAC Installation Looks Like in Campbell 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.
