Takes about a minute. No obligation.
Sizing a furnace for this house starts with what the burner and heat exchanger are actually asked to carry each year. Homes in Richmond County, NY run heat about seven months a year, from October through April. A system that is undersized for that load cycles harder and more often, and the ignition system and heat exchanger accumulate wear that a correctly sized unit would spread more evenly. Contractors pricing a new install here factor that into equipment selection before anything else, because a cheap box installed to a loose spec shows the gap quickly when the burner runs month after month.
Ductwork in a house carries a history that follows no permit date. Half the homes in Richmond County, New York were built in 1974 or earlier (2020-2024 ACS 5-year). That puts a large share of Richmond County homes in a range where the existing ducts were sized and routed for equipment that was replaced at least once since the house was built, and possibly twice. A contractor installing a new furnace has to assess what those ducts will actually carry under the new unit's output, because a mismatch there drives the real cost of the job. The electrical service gets the same read.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or crawlspace and is the piece doing the heating work. A burner assembly inside it ignites the fuel, and a heat exchanger transfers the resulting heat to the air that moves through your home. The blower motor, housed inside the same cabinet, pushes that air out.
The flue pipe runs from the furnace cabinet up and out of the house, carrying combustion gases away. A new thermostat typically mounts on a main-floor wall and is the control point the homeowner interacts with daily. Where the system connects to existing ductwork, a contractor fits the plenum, the sheet-metal collar that joins the furnace cabinet to the supply trunk.

Severe Weather Events in Richmond County
