Takes about a minute. No obligation.
A contractor quoting a central AC installation in Pulaski County has to work out what the house actually demands before settling on equipment. That calculation does not hinge on bracing against a relentless weather load. 77 severe weather events were recorded in Pulaski County, Virginia between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, and a system that is failing or undersized almost certainly got there through age, poor original sizing, or installation shortcuts rather than weather attrition. The contractor's first questions concern the structure: square footage, insulation, duct condition, and what the previous unit was.
Ductwork laid down for an older system may not move air the way a modern central AC unit needs it to. Half the homes in Pulaski County, Virginia were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor pricing a new installation here looks hard at what is behind the walls and in the attic before the equipment question is even relevant, because trunk lines sized for a different era can force a scope change that the unit cost alone never predicted. Electrical service in houses of that age is a second check, since the draw of current equipment often exceeds what the original panel was wired to handle.
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. The indoor air handler or furnace-mounted evaporator coil lives inside, most often in a utility closet, attic, or basement, and is the point where conditioned air enters the duct system.
The refrigerant line set runs between the two units, carrying refrigerant through a pair of insulated copper lines that pass through the wall or floor. The thermostat goes on an interior wall and gives the homeowner control over when the system runs.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the configuration of your house.

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.
