A contractor quoting a central AC install in Madison County has to account for what the local climate actually asks of a system, and that question has a real answer. 144 severe weather events were recorded in Madison County, Virginia between 2015 and 2024. At that rate, severe weather is a steady background condition, not an occasional disruption, which means a system sized too small or installed with shortcuts will show strain sooner rather than later. A contractor who gets the load calculation and refrigerant charge right at the start gives the equipment a fair chance against what this county regularly produces.
Ductwork sized and routed for an older system carries assumptions about airflow, static pressure, and equipment footprint that a modern central AC unit does not share. Half the homes in Madison County, Virginia were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation has to assess whether the existing duct runs will move air the way the new equipment expects, and where they will not, the duct work becomes part of the job before the unit is ever priced. The electrical side follows the same logic: service capacity that met one era's demands gets measured against what a current system will actually draw.
What Goes Into a New Central AC System
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the core of the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet and is the piece the blower pushes air across. These two units are what a contractor is placing and connecting.
The refrigerant lines run between the outdoor and indoor units, carrying the working fluid that makes the whole system function. A thermostat goes on an interior wall and gives the homeowner control over when the system runs. The condensate drain line exits the indoor unit and routes moisture out of the house.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What HVAC Installation Looks Like in Madison County
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 Madison County
Local weather puts real demand on cooling equipment, and that demand shapes what a system needs to handle year after year. Sizing and installing central AC in Madison County means accounting for what the climate actually does here, not what a generic spec sheet assumes.
