Takes about a minute. No obligation.
On a repair call in Drew County, a contractor starts with the ignition system and burner before anything else, because those are the parts that cycle hardest through every heating season. Homes in Drew County, AR run heat about five months a year, from November through March. That cycling loads the igniter, the flame sensor, and the gas valve more than any other components in the cabinet. A heat exchanger or blower failure is real, but in a furnace that has been running through this climate, the ignition circuit is where wear shows up first and where a diagnosis earns its money.
Half the homes in Drew County, Arkansas were built in 1985 or earlier (2020-2024 ACS 5-year). A furnace running in stock that age has likely been serviced, swapped in part, or patched by more than one hand over the years, and what the opened unit contains is rarely what the cabinet suggests from the outside. Heat exchangers crack in patterns specific to how a particular unit was run and maintained. Burners foul in ways that reflect the fuel quality and the venting arrangement the house already had. What this means for repair is that part availability, not labor, is often what sets the final scope of the job.
The Parts of a Furnace a Contractor Checks First
The furnace itself sits in a basement, utility room, or closet and is the piece a contractor starts with. Inside it, the heat exchanger is the first suspect when something smells wrong or the system runs but no heat moves through the house. The burners and the igniter sit nearby, and a failed igniter is one of the more common reasons a furnace simply will not start.
The blower motor pulls air across the heat exchanger and pushes it through the house. A contractor checks it when the furnace fires but airflow feels weak. The flue pipe runs from the furnace to an outside vent, and a blocked or cracked flue can cause the system to shut itself down as a safety measure.
The drawing shows a typical furnace layout, and a licensed contractor determines which parts apply to your specific system and situation.
