A contractor quoting a central AC installation in Hertford County starts from what the local climate actually asks of a system, and the answer shapes every sizing and equipment decision on the job. 57 severe weather events were recorded in Hertford County, North Carolina between 2015 and 2024. At that rate, severe weather is something equipment here encounters now and then, not a standing condition it runs against season after season. A system that fails in this county failed mostly because of how it was sized, how it was installed, or how long it ran without service. Weather is not what drives the install spec here; the heat load, the duct layout, and the quality of the work are what decide whether a new system holds up.
Ductwork laid down for an older system carries assumptions about airflow, trunk sizing, and return placement that a new central AC unit will test immediately. Half the homes in Hertford County, North Carolina were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to assess what the existing duct network will actually do under a new system's demand, not just note that the network exists. If the runs are undersized or the returns are too few, the new equipment will move air unevenly and run longer than it should. That assessment shapes the quote before the unit itself is ever 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, which are the core of the system. Inside, the air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home. These two units are what a homeowner is buying when they invest in central air.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through the wall or ceiling. The thermostat goes on an interior wall and gives the homeowner control over when the system runs and at what temperature.
The drawing beside this text shows how these pieces fit together in a typical layout, and a licensed contractor determines exactly how that applies to your house.

What the Installation Actually Looks Like
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.
