Takes about a minute. No obligation.
A contractor quoting a central AC installation in Galax has to establish what the existing system has actually been through before settling on equipment size or configuration. 61 severe weather events were recorded in Galax city, Virginia between 2015 and 2024. At that rate, severe weather touches this area occasionally rather than constantly, which means it is rarely the variable that drives a sizing decision. What does drive it is the condition of the ductwork, the age of what is being replaced, and how well the original install matched the house. A contractor working here builds the quote around those factors.
Ductwork laid down for gravity furnaces or window units was sized and routed for a different job, and when a contractor prices a central AC install in Galax city, that existing infrastructure is what the quote actually turns on. Half the homes in Galax city, Virginia were built in 1967 or earlier (2020-2024 ACS 5-year). A house that old was built before central cooling was standard in this region, so the ducts and the electrical service reflect whatever the original owner needed, not what a modern condenser and air handler draw. Some of it carries a new system fine. Some of it has to be extended, rebalanced, or replaced before the equipment question even opens.
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 two components that do the heaviest work in the refrigeration cycle. Inside, the air handler mounts in a utility closet, basement, or attic and contains the evaporator coil and blower that move conditioned air through the home.
The thermostat goes on an interior wall, usually in a central living area, and gives the homeowner control over the whole system. Refrigerant lines run between the air handler and the condenser, and a condensate drain carries moisture pulled from the indoor air out of the house.
The drawing shows how a typical central AC system lays out, and a licensed contractor determines exactly what configuration applies to your home.

What happens once a contractor starts the job
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.
