Sizing a central AC system for Franklin County starts with what the climate actually asks of the equipment, not what a spec sheet assumes. 202 severe weather events were recorded in Franklin County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition in this area, and a contractor who ignores it when calculating load and selecting equipment will leave a system undersized for the summers it has to run through. Ductwork routing, equipment placement, and unit capacity all get decided against that local reality.
Ductwork laid in for a furnace was sized and routed for a different load than central air puts on it. Half the homes in Franklin County, Virginia were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC installation in this county will pull open registers and trace runs before pricing the equipment, because what is already in the walls decides whether the existing duct system can carry the new unit's airflow or has to be modified. The electrical panel gets the same look, since a system installed for the heating needs of that era drew less power than a central cooling unit requires. Those two things, the ductwork and the electrical service, are what the job turns on.
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 holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and blower fan that push conditioned air through the house.
The refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that gets routed along the exterior wall or through a chase. The thermostat goes on an interior wall and serves as the control point that tells the whole system when to run.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like 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.

Severe Weather Events in Franklin County
Extreme weather puts a direct load on cooling equipment, and what happens in Franklin County shapes how hard a system has to work over its lifetime. That makes local weather history a practical reference point for sizing and installing central AC here.
