A furnace installation in Greenup County starts with questions about what the equipment will be asked to carry, because the answer here shapes every decision about sizing, insulation of the unit, and how the system is sealed against outside air. 121 severe weather events were recorded in Greenup County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition, and a contractor who quotes a furnace here sizes for sustained load rather than mild winters with occasional exceptions. Equipment spec'd light for this county runs harder to hold temperature, and the gap between adequate and undersized shows up in fuel use and wear long before it shows up in a failure call.

Ductwork laid down for an older heating system carries assumptions about airflow, static pressure, and distribution that a new furnace will test. Half the homes in Greenup County, Kentucky were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor sizing a furnace here has to assess whether those ducts move enough air for the new unit's output, and whether the home's electrical service meets what the new system draws. The equipment itself gets selected in an afternoon; the ductwork assessment is what drives whether the install stays straightforward or expands into a larger job.

What Gets Installed With a New Furnace

The furnace itself sits in the basement, utility room, or closet and is the heart of the system. A contractor sets the heat exchanger and burner assembly inside the cabinet, mounts the blower motor that moves air through the house, and connects the flue pipe that carries combustion gases out through the wall or roof.

The thermostat goes on an interior wall and gives the homeowner control over when the furnace fires and what temperature it holds. The air filter housing and the plenum, the box that feeds conditioned air into the duct runs, attach directly to the furnace cabinet and are set in place as part of the same installation.

The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house and its existing setup.
