A contractor quoting a furnace install in Montague County has to account for what the system will actually run against year after year. 111 severe weather events were recorded in Montague County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition here, and a furnace sized for mild demand will be underbuilt before long. Duct sealing, equipment ratings, and the quality of the install itself all carry more weight in a county where the heating load is this consistent than they would somewhere weather rarely pushes hard.
Ductwork in a house of this vintage was designed around the equipment of its era, and what a contractor finds when they pull the registers or drop into the crawlspace decides how the installation actually prices out. Half the homes in Montague County, Texas were built in 1979 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what a modern furnace requires of its distribution system is where most of the variability in a furnace job lives. A unit that fits the opening can still be a bad match for ducts that cannot move the air a new system expects to push.
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 box that produces the heat. A heat exchanger inside it warms the air that passes through, and a blower fan pushes that air out into the supply side of the home. The burner assembly and the draft inducer motor sit within the cabinet as well.
The flue pipe runs from the furnace to the outside, carrying combustion gases out of the house. A filter rack mounts at the air intake, and a thermostat goes on a wall inside the living space, giving the homeowner control over when the furnace fires. The condensate drain line also connects to the cabinet on high-efficiency units.
The drawing shows a typical furnace layout, and a licensed contractor determines exactly what applies to this house.
