What Is that Sound My HVAC System Is Making?

Get some answers to help you if your heating and air conditioning system is making strange sounds.

Your heating and air conditioning system is one aspect of your home that you likely tend to ignore unless it isn’t working correctly or is making a ruckus. It’s kind of an out of “sound” out of mind situation. But when it starts making strange noises, you may find yourself getting nervous if not down-right anxious.

Noisy HVAC: What’s Normal and What’s Not?

When the seasons change, you may experience more noises coming from your HVAC because of the system switching back and forth between heating and cooling. The valves may make a noise as it switches from one to the other. This is perfectly normal.

Still there are other sounds that may mean you need professional HVAC service. Here are some common sounds you might hear coming from your heating and air conditioning system along with some reasons for those sounds:

  • Buzzing: If your system has a buzzing sound, even when it is not turned on, it may just be coming from the coils in your HVAC. This moderate buzzing sound is typically nothing to cause concern unless it tends to get louder, or accompanies other sounds like metal on metal screeching.
  • Whirring: Some describe this sound as being like a washing machine; this sound typically does not mean there is a problem. HVACs, like any other appliance in your home, have a lot of moving parts, so it is normal to hear sounds; this just means it is working!
  • Clanking: If you suddenly hear loud clanking or banging sounds, it could mean there is an obstruction in your system. In this case, it is wise to shut it off immediate and get in touch with a technician you trust.
  • Banging or Slapping: This sound could be a piece of the ductwork that has come loose and is flapping in the system. Although this isn’t typically an urgent problem, it can be annoying. It’s a good idea to contact an HVAC tech for a service call as soon as possible.
