When your HVAC system keeps you warm in the fall and winter and serves you best in the heat of summer, you won’t even notice it’s there.

In fact, for the most part, the HVAC system is tranquil; the only sound you get to hear is a slow hum.

However, when you start to hear some rattling, banging, or other annoying sounds, it’s an indication there’s a problem.

Here’s what these sounds may mean:

  • Grinding noises
    This can result from dirt and debris stuck in your AC unit, in the furnace’s blower unit, or dirt has made its way into the mechanical components, causing a lot of friction. This friction can cause your entire system to malfunction and shut down.
  • Banging or rattling sound
    If you hear banging or rattling sounds, it may mean that some parts of your HVAC unit are loose.
    The louder the bang, the worse the situation could be. It’s best to turn off your unit and call an HVAC technician as soon as you can.
  • Crashing noise
    This may mean your air duct is probably coming loose or has fallen off.
  • Rumbling noise
    If the noise you’re hearing sounds like low pitch thunder, the heat exchanger may be breaking down, or some rocks may have found their way into your ducts.
  • Buzzing sound
    Buzzing sound is a problem signifying your HVAC’s compressor may have malfunctioned.

It’s important to note that these noises won’t just go away on their own, and the only way to verify the root of the problem is to call in a technician to assess your unit and address the issue.
