A contractor quoting a furnace installation in Switzerland County sizes the system around the heating load this climate places on a house through a normal season, because that is what the equipment will run against year in and year out. 62 severe weather events were recorded in Switzerland County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional fact of life here rather than a standing operating condition, which means installation quality and correct sizing carry more weight than storm tolerance when a contractor is deciding what to put in and how to build it out. Get the sizing wrong and the system strains on ordinary cold days.
Ductwork installed for an older furnace carries assumptions about airflow, trunk sizing, and return placement that may not suit a modern unit at all. Half the homes in Switzerland County, Indiana were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor quoting a furnace replacement here has to treat the existing duct system as an open question, not a given, before any equipment decision makes sense. Whether the runs can handle the new unit's air volume is something that shows up in the crawlspace and the plenum, not in a spec sheet.
What Gets Installed With a New Furnace
The furnace itself sits in a basement, utility room, or closet and is the piece doing the heating work. A burner inside it fires on demand, and a heat exchanger warms the air that passes over it. The blower motor then pushes that warmed air out into the house.
The flue pipe runs from the furnace up and out of the house, carrying combustion gases away from the living space. Alongside the furnace, a contractor installs a new thermostat on an interior wall to give the homeowner direct control over when the system fires and at what target temperature.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.
