A yellow pilot light means your furnace isn’t burning fuel completely. In Brilliant homes, this is often caused by dust buildup, low gas pressure, or poor ventilation. Incomplete combustion can create carbon monoxide, a serious health hazard. If your furnace flame looks yellow or unsteady, shut it off and schedule service immediately with Honest Fix.
Brilliant’s mix of older riverfront homes and hillside neighborhoods near Market Street and School Street often means tight basements and older furnace systems. Many houses were built before modern ventilation codes, so airflow can be limited. Combined with heavy winter use and Ohio River humidity, that lack of oxygen inside the burner causes yellow flames and unsafe combustion conditions.
Honest Fix technicians in Brilliant often find dirty pilot orifices, rusted burners, or blocked air inlets causing the problem. Small utility rooms and sealed basements near Lincoln Avenue or 2nd Street limit oxygen supply. Low gas pressure in older Columbia Gas service lines can also cause the pilot to burn weak and yellow. All of these conditions can reduce heating efficiency and safety.
A yellow or flickering flame means incomplete combustion, which produces carbon monoxide (CO). Because Brilliant homes are often sealed against cold air from the river, CO can linger inside without warning. Honest Fix includes CO testing and combustion analysis with every furnace tune-up to confirm safe operation and protect your family.
Most yellow-flame issues are resolved during a $109 furnace tune-up that includes cleaning, gas calibration, and CO testing. Diagnostic service visits are $99. Every appointment includes Leo the Lion’s magnet, worth $25 off your next repair or tune-up.
No. Even if heat output feels normal, a yellow flame means unsafe combustion and possible CO buildup.
Once yearly—preferably before winter—to maintain safe, efficient combustion.
