Furnace burners should be cleaned at least every season, typically in the autumn before the cold weather arrives. Since this is when furnaces are used most, clogged burners can affect the efficiency of the furnace and raise energy costs.
Burning dust and debris will reduce the oxygen getting to the burners, thus resulting in the furnace running less efficiently and potentially damaging the unit. It is important to note that the burners shouldn’t be cleaned more than once a season in order to avoid damaging them.
If the burners are well maintained and kept clean, only a visual inspection should be necessary each season.
How do you clean furnace burners?
Cleaning furnace burners is an important part of regular furnace maintenance. When burners become clogged with dust, debris, and dirt, it can affect the efficiency of your furnace and even lead to a potential fire hazard.
The job isn’t particularly difficult and can be done in a few simple steps.
Start by turning off the gas supply and electricity to the furnace. Then, find the burners located in a metal box inside the furnace. Remove the box and its cover to gain access to the burners. There should also be a vent tube attached to the box.
This can be cleaned separately.
Use a vacuum cleaner with a brush attachment to clean the burners. Most burners have a central tube surrounded by fins or solid metal plates for air flow. Vacuum the central tube and the fins or metal plates.
Pay special attention to any areas that look corroded or burnt. Make sure to vacuum the crevices between the fins or metal plates.
Once the burners are clean, reinstall the box and the box cover. If the vent tube was removed in the process, make sure to put it back in its place. Turn the gas and electricity back on, and the cleaning process is complete.
Cleaning furnace burners is a great way to ensure that your furnace is running at optimal efficiency. While it’s a job that can easily be done by the homeowner, it’s always wise to hire a professional HVAC technician to handle the task.
They have the knowledge and experience to correctly inspect and clean the burners for maximum performance.
