Sizing a furnace for this county means accounting for what the burner, heat exchanger, and ignition system are asked to do before the first warm week arrives. Homes in Yates County, NY run heat about eight months a year, from October through May. The ignition system cycles every time the thermostat calls for heat, and on a run that long, a marginal component fails long before a homeowner notices anything wrong with comfort. A contractor quoting a replacement here has to match output to the actual load the house places on the equipment, because an undersized unit runs harder and an oversized one short-cycles, and both outcomes wear the heat exchanger faster than a proper install would.

Ductwork laid down for equipment that no longer exists is what a furnace installation in Yates County tends to run into first. Half the homes in Yates County, New York were built in 1969 or earlier (2020-2024 ACS 5-year). That age of construction means the supply and return runs were sized and routed for something different, and a contractor working a new furnace installation has to assess what is already in the walls before anything else can be priced or ordered. If the existing duct layout cannot carry the new unit's airflow without modification, that work gets resolved before the furnace itself is ever touched.
What Gets Installed With a New Furnace

The furnace itself sits in a basement, utility room, or closet and is the unit a homeowner is most likely to recognize. Inside it, a heat exchanger and a burner assembly do the core work, while a blower motor pushes conditioned air outward. A flue pipe runs from the unit to an exterior wall or through the roof to carry combustion gases out of the house.
A thermostat mounts on an interior wall and gives the homeowner control over the system. The contractor also installs a filter housing at the air intake point, and a condensate drain line where the equipment requires one. Each of these pieces connects to the furnace as part of a single installation.
