Sizing a central AC system in Wayne County starts with what the compressor is actually asked to do. Homes in Wayne County, NY run cooling about two months a year, from July through August. A compressor that stands off for most of the year faces a different set of failure modes than one that runs hard through summer after summer: contactors corrode, capacitors drift, and refrigerant leaks go undetected until the first hot day in July, when the homeowner finds out. Contractors who quote a new install here factor that idle period into equipment selection and commissioning checks, because a system that starts poorly on day one of a short season has no extra runtime to self-correct.
Ductwork in this part of New York was built for systems with different output than what a new central AC unit delivers. Whether those ducts can carry the volume a modern installation demands is what a contractor has to establish before anything else on the job gets priced. Half the homes in Wayne County, New York were built in 1968 or earlier (2020-2024 ACS 5-year). Houses on the older end of that distribution often have supply and return runs that were never sized for today's equipment loads, and the electrical service may need evaluation before a new unit can be connected. That assessment shapes the quote more than the unit itself does.
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 heart of the cooling side of the system. Inside, the air handler or furnace with its evaporator coil mounts in a mechanical room, basement, or closet, pulling warm air across the coil and pushing cooled air back through the house.
The refrigerant line set runs between the two units, typically along an exterior wall or through a utility chase, and carries the refrigerant that ties the indoor and outdoor sides together. A thermostat goes on an interior wall where it reads the air temperature and tells the system when to run.
The drawing shows a standard layout, and a licensed contractor determines which configuration and components apply to your specific home.

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.
