The burner assembly on your home’s gas furnace is extremely important. Like most of the other furnace components, they should be serviced once a year by a licensed, qualified technician. The burner assembly can, over time, become misaligned and contaminated by rust and debris. A majority of our modern furnaces have a burner assembly that resembles a small jet engine while in operation, and also the burner assembly will sometimes have cross over tubes, which are small and get clogged easily. After these components get dirty, the problem only worsens due to an improper amount of air to gas mixture, which may actually cause your natural gas bill to be higher than expected. If left unchecked, severe rust can grow and could result in a delayed ignition or a no heat situation. Have your local heating technician inspect and clean the burner assembly each winter to be sure that it is free of dust, dirt, rust, misalignment, and any other contamination that could disruption the flow of gas and combustion air into the furnace. Severely rusted burners must sometimes be replaced.
Cleaning or replacing this component requires training, and a home owner should proceed with caution if attempting to clean the burner assembly.
