A contractor sizing central AC in Nottoway County works from what summers here actually demand, not from a storm tally. 55 severe weather events were recorded in Nottoway County, Virginia between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, which means the load it places on a system over the years is modest. Age of existing equipment, quality of the original install, and duct condition are what drive the decisions on a new installation here. A homeowner replacing a system is almost certainly replacing one that wore out on schedule.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow, routing, and load that a new central AC system does not always share. Half the homes in Nottoway County, Virginia were built in 1973 or earlier (2020-2024 ACS 5-year). That gap between what the house was built around and what a contractor is connecting to it now is where an installation quote either holds or changes. Before a unit gets priced, the existing duct runs have to be checked for capacity and condition, and the electrical service has to be confirmed against what the new equipment draws. Both of those findings shape the job more than the unit selection does.
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 holds the compressor and the condenser coil. Inside, the air handler mounts in a utility closet, basement, or attic and contains the evaporator coil and the blower that moves air through the home.
The thermostat goes on an interior wall where it reads the temperature of the living space and signals the rest of the system. A refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture from the evaporator coil to a floor drain or outside.
The drawing shows the standard layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your home.

What happens on installation day
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.
