Takes about a minute. No obligation.
A contractor sizing central AC here has to account for a compressor that spends virtually its entire life off. Homes in Fulton County, NY have essentially no cooling season — no month of the year is warm enough to call for it. Seals dry out, contactors corrode, and refrigerant-side components degrade when they stand unused across summer after summer without ever being called on. The first genuinely warm day is when the fault surfaces, and it is also when every other homeowner in the county picks up the phone. Getting the installation right from the start, with correct refrigerant charge and sealed connections, determines whether a system that rarely runs still works when it finally has to.
Ductwork laid down for a furnace and nothing else is what a contractor finds in much of Fulton County's housing stock. Half the homes in Fulton County, New York were built in 1954 or earlier (2020-2024 ACS 5-year). Ducts sized for heat alone often run too narrow, too short, or in layouts that leave rooms starved for airflow once a central cooling unit is attached to them. The electrical service is a separate question, but it is the duct system that most often forces a contractor to reprice a job mid-scope, or to recommend a ductless configuration instead.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and holds the compressor and condenser coil. Inside, the air handler mounts in a utility space, basement, or closet and contains the evaporator coil and blower that pull air through the system.
A thermostat goes on an interior wall where it reads the air temperature and tells the system when to run. The refrigerant line set, a pair of insulated copper lines, runs between the air handler and the condenser to connect the two units into a single working system.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation requires in your 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.
Severe Weather Events in Fulton County
Weather puts real load on cooling equipment, and that load is shaped by local conditions. What happens in Fulton County drives how hard a central AC system has to work and how long it stays reliable.
