For a central AC installation in Cayuga County, sizing and refrigerant charge have to be right from day one. Homes in Cayuga County, NY run cooling in a single month of the year, July. The compressor starts and stops hard through July, then sits dormant until the following summer. Seals dry, contacts corrode during the idle months, and the first call of the season is when those faults surface. A contractor quoting a new system here has to account for that stop-and-start cycle, because an undersized or poorly charged unit does not get the gradual exposure that might reveal a problem early.
Ductwork laid out for an old furnace was sized for that furnace. Half the homes in Cayuga County, New York were built in 1958 or earlier (2020-2024 ACS 5-year). A central AC system moves air on a different schedule and in different volumes than the heat source those ducts were built around, so a contractor installing a new unit here measures what is already in the walls before pricing anything else. If the trunk lines are too narrow or the returns too few, the equipment choice follows from that finding, not the other way around. The electrical service gets the same check, because a panel wired for the original load on a house that old often has little room for what a modern condenser draws.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and the condenser coil, which together shed the heat pulled from inside. The indoor air handler, usually placed in a utility closet, basement, or attic, holds the evaporator coil and the blower that moves conditioned air through the home.
The two units connect through a pair of refrigerant lines that run between them, and a thermostat on an interior wall gives the homeowner control over the whole system. A condensate drain line also runs from the air handler to carry away the moisture the evaporator coil pulls from the indoor air.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific home.

What HVAC Installation Looks Like in Cayuga 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 Cayuga County
Extreme weather puts real hours on heating and cooling equipment, and those hours add up differently depending on where you live. A central AC system sized and installed for Cayuga County's actual climate load will hold up better than one spec'd to a regional average.
