Furnace Repair Services in Lorenzo, IL

A fractured heat exchanger is a critical safety issue that can contaminate household air with carbon monoxide. Key warning signs include persistent soot streaks around the burner doors, a pungent chemical smell resembling formaldehyde, burner flames that flicker or burn yellow rather than steady blue, and unexplained headaches among household members. We use fiber-optic inspection cameras in Lorenzo, Illinois to check internal heat exchanger integrity.

Yes. The flame sensor sits directly in the burner flame and generates a micro-amp electrical current when heated to prove to the control board that fire is present. Over time, silica and carbon coat the metal rod, preventing flame detection and causing the furnace to shut off its gas valve after 3 to 5 seconds. Cleaning or replacing this sensor is a routine, fast repair for our Lorenzo, Illinois specialists.

During warm summer months, ambient dust settles onto the furnace burners and heat exchanger surfaces. During the first cold snap, this thin layer of dust burns off, producing a mild, transient burning odor that typically disappears within 30 to 45 minutes. If the smell persists, smells of burning plastic/wiring, or produces visible smoke, shut down the system and call (877) 719-1221 immediately.

High-pitched screeching or metallic grinding usually signals failing sleeve or ball bearings inside the blower motor, or a misaligned blower wheel scraping against the housing.
