Furnaces make noise. Most of the time these noises, though perhaps startling, are quite common and are nothing out of the ordinary.

Of course, some of the sounds you hear coming from your furnace may signal a problem. These individual noises usually come on rather suddenly and are not identifiable as sounds you’ve heard before. When this happens, the solution can be simple, if addressed right away, by contacting Air, Plumbing & Heating Solutions. After over three decades in the heating and cooling business in Baltimore, MD, we’ve likely heard it all. No problem is too big or too small and we’ll be out to ease your mind 24 hours a day-7 days a week.

Here is a list of common furnace noises and when to call the professionals at Air, Plumbing & Heating Solutions:

Banging or Booming Sounds – If you turn on your furnace and, instead of quietly starting up, you hear a “Boom”, it’s typically caused by a buildup of gas from a delayed ignition. This is a serious issue which should only be addressed by a professional. A boom noise could also indicate undersized, or clogged ductwork or that your burners need cleaned and maintained. In any event, a loud boom can be cause for concern and only a professional heating and cooling technician will be able to identify, and remedy, the problem for you.

Clanging Sounds – If you hear a clanging sound, which you believe is coming from your furnace, it may actually be coming from your pipes. In cold weather like that which is common in the Baltimore winters, the pipes connected to your home’s heating system tend to contract. As they warm, the pipes expand and as they then cool, after your furnace shuts off, a clanging noise to radiate from your furnace ducts. This is usually no cause for alarm, however, if this noise is new, or seems unusual, you should have a professional check it out.

Rattling Sounds – A sudden rattling noise can be something as simple as loose plates on your furnace itself. This can be quickly and easily remedied by tightening down the screws which hold the plates in place. If this doesn’t correct the problem, you should call a professional immediately. Rattling in your furnace can be indicative of a leak in your exchanger, which, left unchecked, could result in a carbon monoxide build-up in your home.

Rumbling Sounds – Rumbling coming from your furnace may be a sign your burners are dirty. This can also signal that your pilot light is too high and needs to be adjusted.

Other Common Sounds – Screeching, Chirping, Bumping, or Thudding noises can all point to issues within the mechanics of your furnace. They can be the result of metal on metal, usually caused by a broken fan or belt, a warped plate interfering with the fan, or an internal bearing. Any one of these sounds is cause for concern. Contact a service technician instead of attempting the repair yourself. They are experienced in mechanical repairs and, in the end, can save you from having to replace your home’s heating system.
