What’s That Noise? Common HVAC Noises and What They Mean

January 11, 2019 6:14 pm Published by Leave your thoughts

It often starts with a noise, maybe one that sends a chill up your spine because it sounds a bit “off.” You might ignore it for a while, and then the noise gets worse, or you start to hear a cacophony of noises coming from your HVAC system. The next thing you know, you’re paying huge sums of money to fix a problem you ignored for longer than you should have.

You should definitely call your HVAC service in Central Kansas as soon as you hear an unusual noise from your heating and cooling system. Before you get on the phone with a technician, it might be helpful to understand a bit about your system. The different kinds of noises an HVAC system makes can provide an indication of what the root problem may be. Here’s a guide to what might be the issue with your system.

Air conditioner sounds

Most air conditioning units are incredibly quiet, so hearing any noise from it could spell an expensive problem:

  • Banging and clanking: This usually tells you that your system has a loose part.
  • Squealing: This often has to do with the motor not working properly.
  • Chattering and rattling: These are the most unwelcome sounds to hear, because they usually mean the system is starting to deteriorate. However, it may be easy to fix by checking to make sure there are no twigs or other debris stuck in the system.

Furnace sounds

Furnaces are generally noisier than air conditioners, so if you hear some sounds coming from your furnace, like those knocking sounds that you hear now and then, there may be nothing to worry about. However, there are a few sounds you’ll want to pay attention to—failing to do so could have serious consequences, as carbon monoxide is liable to leak into your home:

  • Squealing and scraping: This might be an issue with the furnace’s blower or heat pump and, at a minimum, the system needs cleaning. A failing blower motor is a sign of poor maintenance or that the furnace is reaching the end of its life.
  • Rumbling: If the furnace is making rumbling or huffing and puffing sounds, this might be an issue with a corroded or dirty heat exchanger. Another possibility is a faulty burner or gas valve issue.
