Is It Normal For A Furnace To Make Noise?

Is it normal for my furnace to make noise? This is a question that many homeowners ask when they start to hear strange sounds coming from their heating system. In most cases, yes, it is normal for a furnace to make noise. However, there are some instances where this may not be the case. In this blog post, we will discuss the different types of noises that a furnace can make and what you should do if you experience one of them.

Normal Furnace Noises

There are a few different types of noises that are considered to be normal for a furnace. These include:

  • The sound of the burner igniting
  • The sound of air whooshing through the ductwork
  • A low humming noise

Popping and clicking are normal as well while the furnace is starting up, and it’s good to keep in mind the older the furnace the more likely it is that you will hear an odd sound or two.

If you hear any of these noises coming from your furnace, there is no need to be concerned. These sounds are all part of the normal operation of your heating system. One thing to keep in mind is that regular maintenance will save you from a bigger headache down the line. Our fall furnace maintenance guide gives you a rundown on what you need to do to prevent future damage from occuring.

Abnormal Furnace Noises

There are a few furnace noises that, while not necessarily indicative of a problem, might be cause for concern. These include:

  • A loud banging noise: This could be an indication that your furnace is starting to wear out and parts are beginning to loosen. If you hear this noise, it is important to have your furnace inspected by a professional as soon as possible.
  • A high-pitched squealing noise: This noise is usually caused by a belt that has come loose or needs to be replaced. If you hear this sound, you should contact a professional to have your furnace serviced.

Other noises to look out for include:

  • Grinding and scraping
  • Rumbling
  • Louds pops and/or bangs
  • Repeated clicking

Any of the following noises should raise some concern, and if paired with any problems a technician should be contacted.
