It doesn’t mean anything good. No, your furnace is probably not going to explode. In fact, that’s not at all what’s going to happen. But a booming furnace, or a noisy furnace period, is a definite sign that you’re in need of a professional furnace repair in Salt Lake City, UT.
Of course, when we say this, we are referring to gas-powered furnaces. All furnaces today are built with safety in mind, but there is always a risk when you’re utilizing natural gas for an appliance in your home. Keep reading to learn more about what booming means for your gas furnace.
Delayed Combustion in the Combustion Chamber
The booming sound that’s caught your attention is the sound of unburned gas in the combustion chamber of your furnace suddenly burning up all at once. The combustion gas isn’t supposed to build up like this, the burners should ignite right away once your furnace cycles on. This booming noise signals that something is preventing the timely ignition of the gas jets, leading to a sudden, delayed ignition.
One reason this might happen is due to problems with the electronic ignition system. That’s right, even gas powered furnaces due utilize a bit of electricity. It used to be that standing pilot lights were the standard way for modern furnaces to light the gas from the gas jets. But now, electronic ignition systems, such as hot surface igniters, are used for this job.
If that igniter isn’t coming on right away, then it can allow for a buildup of combustion gas. Your furnace is designed with a safety mechanism that if the igniter fails, the gas flow will be shut off completely. But this doesn’t account for delayed ignition. If this is the case, you’ll need to have the igniter replaced, or soon your furnace won’t turn on at all.
Another common cause of delayed burner ignition is an accumulation of dirt and grime along the burners, which prohibits their ability to access oxygen and therefore ignite. Carbon and other particles build up over the years, and routine maintenance is designed to take care of this. Otherwise, the burners can be overwhelmed by grime and dust. To fix this issue after the fact, you must have a professional HVAC technician remove the burner and clean it with special chemicals.
