Sizing central AC in an area where severe weather runs at this rate is a local decision, not a catalog one. 290 severe weather events were recorded in Pittsylvania County, Virginia between 2015 and 2024. A contractor quoting an install here has to account for what the equipment will carry across its working life, which means the load profile of this county enters the sizing calculation directly. A unit that fits the square footage on paper can still be under-specified for what this area regularly puts on it. Contractors working here build that into the quote from the start.
Ductwork laid down for older equipment was designed around different airflow targets than a modern central AC unit delivers, and what is already inside the walls of a Pittsylvania County house can either carry a new system or force a contractor to reroute before the unit ever gets wired in. Half the homes in Pittsylvania County, Virginia were built in 1981 or earlier (2020-2024 ACS 5-year). That age of construction means the supply and return layout in a typical house here reflects the assumptions of a different generation of equipment, so a contractor quotes the ductwork before pricing anything else. The electrical service gets the same look, since what a new unit draws has to be confirmed against what the panel actually provides.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the hardware that does the heaviest work in the system. Inside, the air handler mounts in a utility space, basement, or closet and contains the evaporator coil and blower that move conditioned air through the home.
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 contractor also installs the refrigerant line set, a pair of copper lines that run between the air handler and the outdoor unit and carry refrigerant between the two.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.

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.

Severe Weather in Pittsylvania County
Weather puts a real load on HVAC equipment, and that load varies by location. What hits Pittsylvania County shapes how hard a central AC system has to work and how long it holds up, which makes local conditions a practical factor in any installation decision.
