Goettl Technician replacing duct filter

My Furnace Started Rattling: What Does That Mean?

If our furnaces could speak, we would have a much easier time knowing when to repair them and what sort of repairs to schedule. “Hey, psssst! My fan belt is cracked! Get it replaced.”

“You, over here! Did you know my pilot light is failing because of low gas flow? Get somebody on that!”

Sadly, our furnaces can’t speak to us… at least not in words. However, they can speak to us through noises.

When you hear an unusual sound coming from your furnace cabinet or ducts, it usually means there is a repair issue that needs attention. Read on to learn about a common furnace warning noise: rattling.

Possible Reason for Rattling

  • Loose parts: The rattling could be caused by loose parts inside the furnace. This could be anything from a loose blower wheel to a loose motor mount. In this case, the rattling would likely be accompanied by a general clanging or banging noise.
  • Clogged burners: If the rattling is coming from the burner compartment, it could be due to clogged burners. This can cause the burners to vibrate and make a rattling noise.
  • Dirty air filter: A dirty air filter can cause the furnace to work harder than it needs to, which can lead to vibrations and rattling. If you haven’t changed your air filter recently, try replacing it and see if that helps.
  • Ductwork issues: Sometimes, the rattling noise you hear is actually coming from the ductwork, not the furnace itself. This could be caused by loose ducts or ducts that are rubbing against each other.
  • Mechanical issues: Finally, it’s possible that the rattling is a sign of more serious mechanical issues, such as a damaged blower motor or a faulty fan belt. If you suspect this may be the case, it’s best to call the professionals at Goettl to inspect and repair the furnace.

Do Not Try This at Home!

For your safety and the well-being of your furnace, we advise you to leave all repairs that require opening your furnace’s cabinet to licensed professionals. This is especially true for natural gas-powered furnaces, which present the risk of exposure to toxic and combustible gas. Electric furnaces require caution as well because of the hazard of high-voltage shocks.

Goettl Air Conditioning and Plumbing has worked on furnaces since 1939—we’ve seen every type of furnace, and every type of repair. Trust us to handle your furnace repair the right way, not the easy way.

Mr. Farias taught me a lot about the water system in my house and prepared the ground for Mr. Dado to come and fix everything. He was always very honest and delightful. I actually enjoyed his visit.

My technician Jorge (George) Gutierrez was out today performing the a/c system check. He did a fabulous job and identified significant issues and concerns for the longevity of my current 12 year old system. He was very knowledgeable and helpful on what my options are and in the end I’ll be getting a new system instead of worrying about the current system failing in our extremely hot temperatures. He was very respectful of my home and my dog was ecstatic to meet him.

Frank identified the need for new faucets in the master bath and discussed my preferences. The type of faucet being replaced is no longer available (mini wide spread) so he had to do some research to come up with a solution. Had to be ordered, not surprisingly, and we appreciate his conscientious performance.

This was my first service with this company and it was a pleasant one. The technicians were professional and polite and quickly resolved a minor scheduling conflict. Interaction with a sales manager for a quote on needed equipment was equally pleasant.

Signed up for the Sadie membership as a a preventative measure to avoid bigger problems down the line. Had my appointment to check my system today and to my surprise the tech discovered a huge gash in my ductwork! Thankfully so because the ductwork up there is a very tight space which I could never squeeze myself into and would’ve gone unnoticed for who knows how long. Huge thank you to Technician Roy Adame for making the trip out on a Saturday afternoon, going the extra mile to fully inspect the system in a tight space, and fully explaining the possible causes of the damage and the impact it would on the system performance. 🙏🏼🤙🏼🫡👏🏼🙂
