Sizing a furnace for this house means accounting for what the burner, heat exchanger, and ignition system are actually asked to carry each year. Homes in Kent County, RI run heat about eight months a year, from October through May. A contractor quoting a replacement here has to get the load calculation right before anything else, because an undersized unit cycles harder and more often, and the stress lands on the components that were already marginal at the time of install. Poor ductwork sealing or a miscalculated fuel input does not stay hidden long under that kind of demand. The heat exchanger is where the consequences of a rushed install show first.
Ductwork in a house this old was designed around whatever heated it originally, and a new furnace has to run through what is already in the walls. Half the homes in Kent County, Rhode Island were built in 1967 or earlier (2020-2024 ACS 5-year). A contractor installing a furnace here has to trace what the existing trunk lines can actually carry, not what they were labeled to carry, and where returns are cut matters as much as where the unit sits. Electrical service in stock of this vintage was sized for a different load profile, so that gets checked before anything else is quoted.
What Gets Installed With a New Furnace
The furnace itself sits in a basement, utility room, or closet and is the unit a homeowner would walk past every day without thinking much about it. Inside the cabinet, a burner assembly and a heat exchanger do the combustion work, while a blower motor pushes conditioned air out into the house.
A flue pipe runs from the furnace up and out of the house to vent combustion gases safely away. Alongside that, a contractor installs a new thermostat on an interior wall to give the homeowner control over the system, and a fresh air intake where the unit requires one.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
