HVAC System Sounds

4 Sounds You Don’t Want to Hear From Your HVAC System

December 15, 2018

Your HVAC system shouldn’t make a lot of sounds. If you’re noticing abnormal noises in your Charlotte, North Carolina, home, it could signal your system is about to break down. Here are some bad sounds to keep an ear out for and what you should do to stop them:

Clicking

It’s normal for your HVAC system to click when it turns on and off, so don’t worry if you’re hearing that. You should be alarmed if you hear this sound constantly, though. It’s typically a sign of an electrical problem or a failing thermostat. The longer you wait to repair a problem like this, the more serious the issue can become. As a result, you’ll increase the risk of paying higher repair or even replacement costs.

Banging

Banging isn’t a normal sound during any part of your HVAC system’s cycle. In most cases, a loud bang indicates a broken or loose part inside the unit, such as a crankshaft, piston pin or connecting rod. However, it could also signify an unbalanced indoor blower or the need for a new compressor. The only way to know for sure is to have a trusted HVAC service technician diagnose the issue.

Clanking

If you’re hearing clanking from your unit, the problem may be similar to the issues found with banging. Parts may have come loose, the compressor could be wiggling around, or the blades of the blower could be knocking into other parts.

Buzzing

Buzzing can be faint or loud. Therefore, it’s vital to keep an ear out for this tell-tale sign. Unfortunately, it can signify numerous problems, such as:

  • Loose parts in your system
  • A bad blower or fan motor
  • An abundance of dirt in the unit
