Sizing a furnace for this part of Texas starts with what the climate actually asks of the equipment. 99 severe weather events were recorded in Cottle County, Texas between 2015 and 2024. That puts Cottle County in the middle of the national range, which means a contractor cannot treat conditions here as either negligible or extreme. The install has to account for real seasonal load without over-speccing for punishment that does not arrive at that scale. Duct sealing, equipment rating, and the specifics of how the unit is set into the structure are all local calls, not defaults pulled from a product sheet.
Ductwork laid out for an older heating system carries assumptions about airflow, return placement, and trunk sizing that a new furnace does not share. Half the homes in Cottle County, Texas were built in 1960 or earlier (2020-2024 ACS 5-year). A contractor sizing a replacement unit here has to assess what those ducts will actually do with the air a modern furnace moves, not just match the equipment to the square footage. If the existing runs are undersized or poorly routed, the electrical hookup becomes the secondary conversation. The ductwork comes first.
What Gets Installed With a New Furnace
The furnace itself sits in a utility room, basement, or closet and is the unit that generates heat for the house. A burner assembly inside it ignites the fuel, a heat exchanger transfers that warmth to the air moving through the cabinet, and a blower motor pushes the heated air out toward the rest of the home.
A flue pipe runs from the furnace to an exterior vent, carrying combustion gases out of the house. Alongside the furnace, a contractor installs a thermostat on an interior wall to control when the unit fires, and a filter housing at the air intake to keep debris out of the cabinet.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specifics of your home.
