Takes about a minute. No obligation.
A compressor that never runs still ages. Seals dry, contactors corrode, and refrigerant can migrate into the compressor oil during long cold-side shutdowns, leaving the system in poor condition before it ever sees a load. Homes in Cortland County, NY have essentially no cooling season — no month of the year is warm enough to call for it. A contractor quoting central AC installation here has to account for that: the new system will spend the vast majority of its life parked, and the quality of the installation decides how well it survives that, not how hard it runs.
Ductwork sized for an older heating system and an electrical panel that was not designed for a modern central AC unit are what a contractor has to assess before anything else on an installation job here. Half the homes in Cortland County, New York were built in 1961 or earlier (2020-2024 ACS 5-year). That distribution shapes what the work actually involves: a contractor pulling new equipment into a house like this is working out whether the existing duct runs can carry the airflow a new system requires, and whether the service panel has the capacity to run it. Where they cannot, the ductwork or the electrical becomes the larger part of the job.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a pad beside the foundation, and holds the compressor and the condenser coil. The indoor air handler or furnace-mounted evaporator coil lives inside, typically in a basement, utility closet, or attic, and is where the refrigerant does its work on the air moving through your home.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides through a small penetration in the wall. The thermostat goes on an interior wall where it can read the air temperature and signal the system when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house.

What Happens on Installation Day
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 Cortland County
Weather conditions drive how hard heating and cooling equipment has to work, and how often. A central AC system sized and installed for what Cortland County actually delivers will hold up where a generic install may not.
