A contractor quoting a central AC installation in Radford city starts by working out what the existing system has actually been up against. 34 severe weather events were recorded in Radford city, Virginia between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, which means a system that has struggled or failed here almost certainly did so because of how it was originally sized, how well it was installed, or how long it ran without attention. Those are the variables a contractor accounts for when specifying new equipment and planning the install.
Ductwork laid down for an older heating system carries assumptions about airflow, routing, and sizing that a modern central AC unit does not share. Half the homes in Radford city, Virginia were built in 1976 or earlier (2020-2024 ACS 5-year). That gap between what the house was built for and what a contractor is now fitting into it is where most of an installation's complexity lives. Electrical service is part of that same audit: a panel from that era often predates the draw a current system requires, and a contractor establishes that before anything else gets priced.
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 air handler mounts in a utility closet, basement, or attic and houses the evaporator coil and blower that move conditioned air through the home.
The refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through insulated copper tubing along an exterior wall or through a chase. A condensate drain line also ties into the air handler, routing the moisture the coil pulls from indoor air to a floor drain or outside.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your specific home.

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.
