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 Moraga, California to check internal heat exchanger integrity.

This symptom is known as short-cycling. The most common culprit is a severely restricted airflow caused by a clogged furnace filter, which traps intense heat inside the cabinet and trips the high-temperature safety switch. Other potential causes include a malfunctioning draft inducer fan, an oversized unit, or a blocked chimney flue exhaust. Our Moraga, California technicians can calibrate and clear the system safely.
