A contractor quoting a furnace installation in Concordia Parish has to get the load calculation right before anything else. Homes in Concordia Parish, LA run heat about five months a year, from November through March. A unit that falls short on capacity will run longer cycles to meet thermostat demand, and the heat exchanger and burner carry that extra strain every heating season with almost no off-season to offset it. That wear shows up in the ignition system first. Sizing to the actual load here is what determines how long the equipment holds.
Ductwork laid down for a previous generation of equipment was sized for that equipment, and a new furnace draws differently. Half the homes in Concordia Parish, Louisiana were built in 1977 or earlier (2020-2024 ACS 5-year). When a contractor prices an installation in Concordia Parish, the duct system gets measured and checked before the unit gets specified, because what is in the walls may not carry the new load without modification. The electrical service gets the same look. A house that has been heated and cooled for decades under different equipment is not automatically wired for what replaces it now.
What Gets Installed With a New Furnace
The furnace itself sits inside the house, most often in a utility closet, basement, or attic, and it is the unit that produces heat. A heat exchanger inside the cabinet is where combustion gases warm the air without mixing with it. A blower motor then pushes that warmed air out into the supply side of the home.
The flue pipe runs from the furnace cabinet to an exterior wall or roof and carries combustion exhaust safely out of the house. Alongside it, the gas valve and burner assembly control fuel delivery and ignition, and the air handler or blower cabinet connects the furnace to the rest of the system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
