Step 1 of 3: Equipment

What kind of equipment?*

Sizing a central AC system for Oswego County is less forgiving than it looks on paper. Homes in Oswego County, NY run cooling in a single month of the year, July. The compressor starts, runs, and shuts down across that one window, and a contactor or refrigerant charge that was set wrong at installation will sit untested for the better part of a year before anyone finds out. A contractor has to get the load calculation right the first time, because there is no long season of daily cycles to surface a marginal install early. Ductwork that leaks or an outdoor unit that was placed without regard to airflow will lose its one chance to prove itself each summer.

Ductwork sized and routed for a heating system carries different demands than a central AC installation puts on it. Half the homes in Oswego County, New York were built in 1971 or earlier (2020-2024 ACS 5-year). That means a contractor evaluating a job here is checking whether the existing runs reach the right rooms, whether the trunk lines move enough air, and whether the path from the air handler to each register actually works for cooling. Electrical service in houses of this vintage was drawn up for a smaller load than a modern condensing unit draws. Both of those questions get answered before any equipment gets priced.

What Gets Installed With a New Central AC

The outdoor condenser unit sits outside the house, usually on a concrete pad beside or behind the building, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or attic. These two units are the core of what a contractor puts in.

A copper refrigerant line set runs between the indoor and outdoor units, connecting them through an exterior wall. The thermostat goes on an interior wall where it reads the living space and tells the system when to run. A condensate drain line also gets routed from the indoor coil to a suitable drain point.

The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.
