 3 Sounds Your Furnace Shouldn’t Make

There is, of course, more than one way to figure out whether or not you need a furnace heater repair in Sutton. However, it’s best to avoid situations that involve being entirely without heat.

One of the earliest warning signs of trouble that you can pick up on is the development of concerning noises. These are noises that your furnace has never made before which can, and probably should, worry you. While they don’t indicate an immediate breakdown, concerning noises can warn you that there are issues to address before they cost you the functionality of your heater.

Let’s discuss three of the most important warning sounds to listen for.

3 Noises You Never Want Your Furnace To Make

No furnace runs without making any noise. That doesn’t mean that new or concerning sounds should be ignored though. These are three noises that a malfunctioning furnace may make which should prompt you to reach out to get the system checked and repaired.

  1. Screeching. This noise is an unpleasant one which hopefully prompts a quick response. Screeching is made when metal scrapes against metal. Common causes of this noise in a furnace can include dried-out motor parts that need lubrication or even a bent fan blade that is scraping around its housing. To prevent the damage from worsening, you’ll want to get this noise checked out ASAP.
  2. Hissing: Don’t mistake hissing for the same thing as regular airflow through your system. Hissing indicates that air is forcing its way out of a small space and that really isn’t something that should be happening in your furnace. The best-case scenario for this noise is a dirty air filter that is hindering the entrance of air into the system. The worst-case scenario is that the hissing is created when combustion gases are leaking out of a crack in your heat exchanger.
  3. Booming: Last but certainly not least, see if you pick up on a booming noise when your gas furnace turns on. This is a sound that will indicate something causing a delay in the ignition of the gas supply in your furnace. When the gas builds up and finally ignites, it creates a boom. The thing is, this is something you want to address ASAP as it can and will cause added damage to your furnace.

What Are Normal Furnace Noises?

One way to figure out if the sound you’re hearing should be a cause for concern is if it isn’t a normal one. But what are the normal noises? The sounds a properly functioning furnace can make include:

  1. A click when the system turns on.
  2. The sound of the blower motor running.
  3. The whoosh of air flowing out of the system and throughout the house.

If you hear noises that are outside of these, then there is a chance that you may need to have a technician take a deeper look. That’s when you can come to us for assistance.
