Sizing a furnace for Pecos County starts from what the equipment will actually be asked to carry, not from a catalog default. 277 severe weather events were recorded in Pecos County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating life of any system here, which means a contractor has to account for it before settling on equipment capacity, duct layout, or sealing spec. A unit that fits the square footage on paper but ignores what this climate imposes on heating loads will fall short before long.
Ductwork laid out for one generation of heating equipment does not automatically carry the next. Half the homes in Pecos County, Texas were built in 1981 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a new furnace here has to look at what the existing duct system will actually move before the equipment selection means anything. If the runs are undersized or the layout does not match the load, the new unit performs against the house rather than with it. The electrical service gets the same check, because what a modern furnace draws may not match what the original wiring was built to handle.
What Gets Installed With a New Furnace
The furnace itself sits inside the house, most often in a utility closet, basement, or attic. It holds the heat exchanger and the burner assembly, which is where fuel combustion happens and where heat enters the airstream. The blower fan, mounted inside the same cabinet, pushes that heated air out into the supply side of the home.
The flue pipe runs from the furnace cabinet up and out of the house, carrying combustion gases away from the living space. Alongside it, the gas line connects to the burner, and the thermostat goes on an interior wall where it reads the temperature of the home and signals the furnace when to fire.
The drawing shows the general layout of these components, and a licensed contractor determines exactly what applies to this house.
