Meaning of Various Noises from Your Furnace

When a furnace is operating properly, chances are you won’t notice it all that often. When issues are taking place, however, there are often some notable signs – including noticeable sounds that indicate these problems in certain cases.

When you work with the team with At Your Service Plumbing, Heating & Air, we’re happy to provide numerous HVAC services, including significant attention to your furnace. This is especially important this time of year, as we move from the cooler fall to the cold winter season and homeowners need a furnace that’s operating optimally. What are some common noises that might indicate an issue in the furnace, and what are they possibly telling you or our HVAC repair pros? Let’s take a look.

meaning noises your furnace


Have you begun to hear a loud, metal-on-metal clanking sound that’s clearly coming from your furnace, chances are this is an issue with the blower wheel. In such cases, you should immediately cut off power to your furnace and contact our HVAC professionals – not only does a blower wheel require professional repair or replacement if damaged, leaving it for even a week or two longer will just increase the damage done, and therefore the cost you pay. Do not delay in calling us if you notice this problem.

Booming or Banging

If you hear a more abrupt banging or booming noise from the furnace, this often means a dirty burner that’s been clogged up by dust and other debris. This is not only a potentially harmful problem to your furnace, but also a dangerous one – in the worst of cases, it can lead to a small explosion in the home.

Unless you have specific HVAC training, we strongly recommend against trying to clean the burner on your own. Mistakes here are both costly and a risk to your safety. Call in our HVAC pros for any gas burner issues or suspicions.


What if your sound is a loud, high-pitched screech? This is usually a malfunctioning blower motor, meaning even though the furnace is producing warm air, it will not be properly circulated throughout the home.

Luckily, this issue is often minor – in these cases, just some basic lubrication might be needed. In others, the fan will have stopped working altogether, in which case you need one of our HVAC technicians to assess the problem (we’re also happy to help with lubrication if you’re unsure how to do this).


Finally, a rattling sound from the furnace may indicate a broken heat exchanger. This will lead to the furnace building up too much heat, which will eventually crack your heat exchanger and lead to major risks, including carbon monoxide poisoning. Any rattling sound should cause you to call our team right away.

During this very unusual time, we have put a plan in place to do our part to help keep our community safe. First and foremost, we are going to stay CALM, PATIENT, KIND, and POSITIVE!

There is much to consider regarding the COVID-19 virus (Coronavirus) and its possible transmission in your home. While there are various and effective indoor air quality measures available to help protect your safety, including duct sanitization, ultraviolet (UV) germicidal light treatment, and HEPA air filters, they alone cannot protect from all forms of COVID-19 transmission. It is important to follow all official guidelines for preventing the spread of this virus.

Because we have a direct impact on the indoor environment, here are practical steps we are going to take to keep people safe:

  • Wash our hands frequently and thoroughly with soap and water
  • Cover our nose and mouth when sneezing or coughing
  • Wash our uniforms every day including cleaning our belts
  • Stay home if we are feeling sick
  • Offer a warm smile and friendly greeting instead of a handshake
  • Wear shoe covers and latex gloves in homes and businesses
  • Wipe down surfaces and equipment touched in a client’s home with disinfectant wipes
  • Wipe down door handles, steering wheels, gear shift lever every day
  • Wipe down pens, clipboards, tablets, cell phones, and anything else passes between techs and clients.
  • We have masks on each truck and will wear them at client’s discretion (Currently the CDC does not recommend that people wear masks to prevent the spread of COVID-19)
  • We are complying with all recommendations and guidelines from state agencies and will be proactive in our efforts to see that our team members and clients are protected.

As the situation unfolds, we will take each day one at a time and ensure we are being smart, supportive, and helping all those we can in our community.

Thank you for your continued support!
