A contractor quoting a central AC install in Waynesboro starts with the house: its square footage, insulation, window placement, and how the existing ductwork runs. 36 severe weather events were recorded in Waynesboro city, Virginia between 2015 and 2024. At that rate, severe weather is a real but occasional presence, not the defining variable a contractor has to design around. What drives the sizing calculation is the structure and how it holds or loses conditioned air, and a contractor who skips that work and pulls a unit size from a chart will leave the system short-cycling or struggling on the hottest days regardless of what the weather does outside.
Ductwork sized and routed for older equipment is what a contractor runs into in a significant share of Waynesboro homes. Half the homes in Waynesboro city, Virginia were built in 1969 or earlier (2020-2024 ACS 5-year). When the trunk lines and branch runs in a house were never intended to carry what a current central AC system moves, getting the new unit to perform as rated depends on what those runs can actually handle, not on the unit itself. An electrical service of that era may also need evaluation before a new system can be connected. The equipment gets selected after the house tells the contractor what it will accept.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the two components that shed heat to the outside air. Inside the home, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and the blower that moves conditioned air through the house.
The thermostat goes on an interior wall where it reads the temperature of the living space and signals the system to run or stop. A refrigerant line set, a pair of insulated copper tubes, runs between the air handler and the outdoor unit to connect those two halves of the system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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.
