A contractor quoting a central AC installation in Randolph County has to think past catalog sizing. 232 severe weather events were recorded in Randolph County, North Carolina between 2015 and 2024. At that rate, every system installed here runs against severe weather as a routine part of its life, not an exception to it. That changes what a proper installation looks like: duct design, unit placement, and equipment capacity all get weighed against what this county's air regularly does to a running system. A contractor who skips that step leaves the homeowner with equipment sized for a quieter climate.
Ductwork sized and routed for older equipment is what a contractor meets in a large share of houses here. Half the homes in Randolph County, North Carolina were built in 1985 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were built to carry and what a modern central AC system actually moves is where an installation job gets complicated or stays simple. Whether the existing runs can handle the new airflow without pressure loss or return-air problems is something a contractor has to measure, not assume. Electrical service gets the same look, since a panel that has not been touched since the house was built may not have the capacity a new system draws.
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, which are the core of the system. Inside, the air handler or furnace-based evaporator assembly mounts in a utility space, basement, or closet and circulates air across the evaporator coil.
The thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. A refrigerant line set connects the indoor and outdoor units, running through the wall or floor, and a condensate drain line carries moisture pulled from the air out of the house.
The drawing shows a typical layout, and a licensed contractor determines what fits the specific configuration of your home.

What HVAC Installation Looks Like in Randolph 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.
