Why Is My Furnace SO LOUD?

Why is my furnace SO LOUD?




My furnace is SO LOUD! It does a good job heating my home, but it sounds like one of those old two-engine private airplanes revving up for a takeoff. Is this a sign that there may be something wrong with my furnace, and is it as dangerous as it sounds?




Dear Customer,

When your furnace starts making unusual noises, it’s a definite indicator of a problem that needs solving. The most important factor to determine is WHEN the noise starts up.

If your furnace only makes a loud bang when it kicks on, it could have a dangerous problem called delayed ignition. This happens when unburned oil builds up in the fire box chamber and is ignited all at once. You should call for emergency service if you suspect you have a delayed ignition problem.

If your furnace makes loud noises while the furnace is running, the source could be several things. You may have a problem with the fan that blows hot air through your vents. The fan bearings may be worn and need to be replaced. Actually, any motor (such as the burner motor or circulator motor) could be making the racket. Fortunately, these problems are not as dangerous as they sound, but you definitely need to get the problem fixed as soon as possible.

Just Call Heritage (or schedule service online!) and make an appointment to have the complete heating system checked. Our trained technicians will be able to quickly tell you which part is making the racket and fix it.
