Loud Pop

If you hear a loud bang or pop from your furnace there are two common reasons: either your furnace’s burners are dirty of the furnace’s air ducts are expanding and contracting.

Dirty Furnace Burners

If your furnace’s burners are dirty there is no reason for alarm but this is a chore you should address. The dirt on your furnace’s burners prevent them from igniting, causing an abundance of gas to build. So, naturally, when your burners do ignite, you’ll hear a loud bang. These small explosions may ultimately crack the heat exchanger, which is an expensive repair. To prevent this problem clean your furnace burners regularly.

Expanding and Contracting Air Ducts

If your furnace has metal air ducts, it is likely you have heard a loud popping noise coming from your furnace. It is common to hear your air ducts expanding contracting as the furnace’s blower turns off and on; however, it may also indicate that your air ducts are undersized or poorly constructed. To ensure your furnace is functioning properly call, Denver’s Best Heating and AC Repair.

Squealing

A high squealing furnace is a symptom of a number of problems relating to the blower, shaft bearings, or your blower is simply malfunctioning. While these problems may sound severe, they can typically be resolved quickly, and efficiently. Still, we recommend addressing these problems sooner rather than later to prevent future problems and complications.

Metal on Metal

If your furnace is making a noise that sounds like metal rubbing against metal, turn off your furnace, and call Denver’s Best and Heating and AC Repair. This noise cannot be ignored.
