Takes about a minute. No obligation.
A contractor sizing a central AC system in Albany County has to get the load calculation right the first time. Homes in Albany County, NY run cooling in a single month of the year, July. The compressor, condenser fan, and contactor spend most of the calendar waiting, then start hard when July arrives. An undersized unit or a poorly sealed duct run will not degrade quietly over many months of steady use; it will fail on the first day it matters, when the system runs hardest and service calls back up. That makes the install itself the point where shortcuts cost the most.
Ductwork laid down for a furnace or an older forced-air system was sized and routed for different pressure and airflow than a central AC unit draws today. Half the homes in Albany County, New York were built in 1964 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here has to assess what those ducts will actually carry before the new equipment gets spec'd, because the ducts are the constraint that moves the job, and the electrical service in houses of this vintage often needs the same look before anything gets quoted.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and the condenser coil. Inside the house, the air handler mounts in a utility closet, attic, or basement and holds the evaporator coil and the blower that moves air through the home.
The thermostat goes on an interior wall where it reads the air temperature and tells the system when to run. A refrigerant line set connects the indoor and outdoor units, running through the wall or floor, and a condensate drain line carries moisture from the evaporator coil out of the house.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits into 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.
