A furnace installation in Licking County starts with a sizing decision that has to account for what this area actually puts equipment through. 180 severe weather events were recorded in Licking County, Ohio between 2015 and 2024. At that rate, severe weather is part of normal operating life here, not a periodic outlier a system might avoid. A contractor who treats this like a mild-climate job will spec equipment that struggles under real-world demand. Proper installation means the load gets factored in before the unit is ever chosen.
Existing ductwork is what a furnace installation turns on in a county with this housing profile. Half the homes in Licking County, Ohio were built in 1980 or earlier (2020-2024 ACS 5-year). Ducts put in for an older system carry a load profile that a new furnace may not match, and a contractor has to assess whether the trunk lines and branch runs will move air the way the new unit needs before any other decision gets made. If the electrical service is also original to the house, that gets checked alongside it. The ductwork is the variable that sets the scope.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or closet and is the unit a homeowner sees when they look at the system. A contractor mounts the heat exchanger and burner assembly inside that cabinet. The blower motor lives in the lower section of the same cabinet and pushes conditioned air out through the supply side.
The flue pipe exits the furnace and runs to an exterior wall or up through the roof, carrying combustion gases out of the house. A new thermostat goes on an interior wall and gives the homeowner control over the whole system. The condensate drain line, present on high-efficiency models, runs from the cabinet to a floor drain or utility sink nearby.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to this house.
