The last thing you want on a freezing winter night is the furnace in your home to suddenly stop working. However, you can prevent this scenario if you make sure to choose furnace repair and maintenance services on time.

Regardless of the age of your HVAC system, it can develop problems due to daily wear and tear. When a furnace is in good shape, you rarely hear any sound. However, if your furnace is making different sounds lately, it may be a sign that the system is failing.

Here are 5 different sounds coming out of your furnace that requires your immediate attention. Call the furnace repair and maintenance technicians immediately to keep your furnace working in the best condition.

  • Banging Noise
    If you hear loud rattling, clanking, banging or thumping noises, it indicates a problem with the motor or the blower assembly. These noises often show that a component in the system is coming loose. It is important to get the furnace repaired before it leads to massive damage.

    If you hear a loud banging noise when the system is running, shut off the system immediately. The sound can often come from motor bearing or the blower may be out of alignment. Call a technician to get the system inspected.

  • Squealing or Screeching
    If you hear a distinctive squealing or screeching, the motor bearing may be having some problem. While motor belts are not expensive to repair, make sure to replace them before they break as the furnace will no longer work if the belt is broken.

    A squealing noise can be treated by adding lubricant. However, if you are doing it yourself, use the right oil as common household lubricants such as WD-40 is too lightweight for the furnace.

  • Clicking Sound
    When the HVAC system is turned on or off, clicking noise is normal. However, if you hear the clicking sound coming out of the control panel repeatedly, it may indicate some problem with the system. Get it inspected by furnace repair and maintenance service professionals.
  • Thwapping
    Do you hear a fast thwapping sound when the blower is running? Chances are there’s something stuck in the blower blades. Moreover, there may be something inside the housing that is coming in contact with the blower when it is turned on.

    While this noise is not critical, but if an object is creating resistance, the motor may wear out sooner. So make sure to get your system inspected.

  • Popping
    The popping sound indicates that your furnace is working harder. The burners may be dirty or are taking longer to ignite than what they should actually take. A popping sound can indicate that the furnace is failing.

    If your furnace is popping, call a HVAC technician immediately as it can become a fire hazard.

    If you hear any abnormal sound coming out of your system, hire an experienced furnace repair and maintenance professional to check it out. Don’t ignore the sound as ignoring them can lead to expensive repair on a later date. Get in touch with HVAC technicians today. Call the experts at 801-467-1561.
