A contractor quoting central AC installation in Floyd County has to size the system for what this area actually asks of it. 101 severe weather events were recorded in Floyd County, Virginia between 2015 and 2024. At roughly the national midpoint, that rate of severe weather is real but not exceptional, so it does not override the fundamentals. A unit that is undersized or installed with leaky duct connections will struggle through an ordinary summer, regardless of what any one storm season brings. The contractor's first job is getting the load calculation and the refrigerant charge right.
Ductwork laid down for an earlier generation of equipment was designed around different airflow requirements, and when a contractor brings in a new central AC system, what is already in the walls either fits those requirements or it does not. Half the homes in Floyd County, Virginia were built in 1987 or earlier (2020-2024 ACS 5-year). That means a significant share of homes here have duct runs that a contractor has to measure and assess before the new unit can be matched to them. If the existing ductwork cannot move the air a modern system pushes, the installation scope widens past the equipment itself. The electrical service that older construction carries is a second check, since a new condenser draws what it draws regardless of what the original wiring was planned for.
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 the coil that releases heat to the outside air. Inside the house, the air handler or furnace cabinet stands in a utility space, basement, or attic and holds the evaporator coil that cools the air before it moves through the home.
The refrigerant line set runs between the two units, connecting the indoor and outdoor sides through a small penetration in the wall. A thermostat goes on an interior wall where it reads the temperature of the living space and tells the system when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to this particular 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.

Severe Weather Events in Floyd County
Local weather puts real stress on cooling equipment over time, and how hard a system works is shaped by what the climate around it does. That makes installation sizing and equipment selection a local decision, not a generic one.
