A furnace installation in Andrews County is a local engineering decision, not a catalog selection. 63 severe weather events were recorded in Andrews County, Texas between 2015 and 2024. At that rate, severe weather is a periodic fact of life here, present enough that a contractor accounts for it but not so relentless that it dominates the installation brief. What drives sizing decisions and equipment choices is the heating load this climate puts on the structure itself: how the house is built, how it loses heat, and what the duct system can actually carry. A contractor who gets those variables right is doing the work the weather record here demands.
Existing ductwork in a house this old was laid out for a different system entirely, and a new furnace has to move air through whatever that original layout allows. Half the homes in Andrews County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor sizing a replacement has to walk the duct runs and measure what they can actually carry before the equipment selection makes sense. If the ductwork is undersized for a new unit's output, the furnace performs below spec regardless of what was purchased. The electrical service gets the same check, since draw requirements have shifted across the years that separate original construction from current equipment.
What Gets Installed With a New Furnace
The furnace itself sits inside the house, most often in a utility closet, basement, or garage. It holds the heat exchanger, the burner assembly, and the blower motor in a single cabinet. That cabinet is what a contractor sets in place and connects to everything else.
The flue pipe runs from the top or back of the furnace to an exterior wall or through the roof, carrying combustion exhaust out of the house. Alongside the furnace, a contractor installs the air handler components and the thermostat, which mounts on an interior wall and gives the homeowner direct control over the system.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of this house.

In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather Events in Andrews County
Weather in West Texas puts real hours on heating and cooling equipment, and those hours compound over years. A furnace sized and installed for local conditions handles that load differently than one built to a national average.
