A woman is listening to something with her hand to her ear.

How has your furnace been operating lately? Is the system working around the same as always, or has your furnace begun to exhibit some strange new quirks? If you have begun to have some concerns with the way your furnace is functioning, then we’d advise reaching out to a technician for assistance.

One of the indicators that you can be on the alert for is the development of new noises from your system. Different sounds that weren’t there before can be a sign of different issues. If you pick up on any of the following sounds, we’d say now is a great time to talk to our team about furnace repair in Portland, OR.

6 Noises Your Furnace Should Not Make

If your heater starts to sound “off,” we’d suggest getting it checked. Even if the solution is a simple one, you’ll sleep better at night knowing that your furnace is operating correctly and safely. Here are the noises that you should pay attention to.

  • Rattling : It sounds like your heater has developed the shakes or something like it. While the system isn’t about to fall apart, what you may be hearing could indicate loose parts that need to be tightened before they break free and create additional damage.
  • Booming : If you have a gas furnace that starts to boom when it turns on, then you should turn the system off and call for repairs. What may be happening is that something, like dust build-up, is delaying the ignition of the gas. When the fuel finally does ignite, it creates a small explosion, leading to the boom.
  • Buzzing : Your heater has begun to buzz and you aren’t sure if that is normal or not. If a filter change doesn’t stop this noise, then it is worth talking to a technician. Buzzing can indicate a range of issues from electrical problems to a leak in your ductwork.
  • Screeching : A high-pitch noise like this is one you are going to take note of. When you hear a furnace screeching or squealing, what you are hearing is metal scraping against metal. The likely cause is a dry blower motor belt or motor bearings.
  • Short cycling : When your furnace turns on and then only runs for a few minutes before turning back off, it is referred to as short cycling. Aside from this causing trouble for your home comfort, this irregular cycling issue also puts added strain on your furnace and hikes up your energy bills.
  • Clicking : Last but not least, make sure to have your furnace checked if it is clicking continuously. A single click when you turn on the thermostat isn’t a problem. Clicking throughout the use of your furnace can indicate trouble with the thermostat connection or even problems with the heating elements in the furnace.

If it seems like something is going wrong with your furnace, it is better to be safe than sorry: reach out to a professional to check things out!
