Furnaces are complex, mechanical devices with many moving parts and functions. While newly installed furnaces are quieter than ever, they’re still going to make some noises. Still, there are some out-of-the-ordinary heating noises that you should be alerted by. These sounds could indicate that something is wrong with your system.

Heating noises, furnace sounds, and what you should not ignore

You should immediately contact a professional technician at Allbritten for furnace repair if you hear any of these noises.

  1. Buzzing noises
    If you hear a buzzing noise, you should get the system checked by a professional furnace repair technician from Allbritten. A buzzing noise usually indicates that something is wrong with the capacitor or the fan. An experienced technician will use specialized tools to determine the exact cause of the noise.
  2. Vibrating noises
    Another noise that indicates furnace repair is a loud vibrating or thumping noise. Again, you should call a professional to get your heating system checked if you hear this noise. The noise is usually caused when the motor becomes out of balance.

    The vibrating noise may also occur due to an unbalanced blower wheel. Getting the system checked will help in detecting and resolving the problem with the furnace.

  3. Squealing noises
    A squealing noise can occur for many reasons. An experienced technician will use specialized tools to find out the cause of the squealing noise.

    Generally, the noise occurs due to a lack of lubricant in the shaft bearing. Also, the noise could indicate a problem with the blower motor. Finally, a loose blower belt can cause a squealing noise, too.

  4. Banging noises
    Your furnace can make a banging noise due to many reasons. Some of the probable causes of the banging noise include the following:

    • A delay in ignition due to dirty burners
    • The excessive buildup of gas inside the chambers
    • A fault in the heat exchanger
  5. Rumbling sounds
    A loud rumbling sound coming from the furnace is usually due to an issue with the blower wheel. A faulty burner could be causing the noise, or the noise could also be caused by rapid expansion and contraction of the air ducts. The issue is common when the ducts are made of metal. An experienced technician will inspect the furnace and perform the necessary repairs.
