A contractor sizing up a furnace repair in Andrews County starts with the unit itself: how old it is, how it was installed, and how consistently it has been serviced. 63 severe weather events were recorded in Andrews County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a standing condition, which means the equipment has not been grinding against an unusually punishing load. When a heat exchanger cracks or a blower motor fails, the weather record is unlikely to be the explanation. Deferred maintenance and component age are what a contractor is most likely to find.
Furnace parts do not age on a calendar; they age under load, and the load in older stock is cumulative. Half the homes in Andrews County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). A furnace that has been cycling through West Texas winters in a house that old will, when a contractor opens it, show wear on heat exchangers and limit switches that has outpaced what the model number alone would suggest. Some of those parts are still stocked. Others require a contractor to source them, and whether a particular component is available determines whether the repair closes in one visit or stretches.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the core of the furnace cabinet and is where a contractor looks early in any repair call. Cracks or stress fractures there affect the whole system. The burner assembly, just below it, is another first stop: when ignition is weak or inconsistent, that is where the problem usually lives.
The blower motor and its fan wheel sit in the lower section of the cabinet and push conditioned air into the supply plenum. The igniter and flame sensor are small components mounted near the burner, but a failed igniter or a coated sensor will shut the furnace down entirely. The control board ties all of these together and is what a contractor reads for fault codes before touching anything else.
The drawing shows a general furnace layout, and a licensed contractor determines which components apply to the specific equipment and configuration in your home.
