How to Tell Your Heating and Cooling Service Provider What Sound Your System is Making

Heating and cooling systems all have a normal range of sounds that they consistently make, but they should not be disruptive or really even heard. If your system is making weird sounds, it normally indicates that it’s in need of heating and cooling service.

Take note of the sounds you’re hearing, turn off the system and call in experts like Airtronic Heating & Cooling. You might find that your system simply has a broken part, but it might also be an indicator that it needs a bigger repair. Understanding how to describe the sounds your system is making will help the heating and cooling service technician troubleshoot the problem.

Here are a few of the more common sounds that show a need for heating and cooling service and their probable causes:

  • Rattling, banging, clanking or thumping—while rattling typically indicates a loose part, louder banging or thumping sounds may mean a part of your heating and cooling system has completely busted or become detached.
  • Repetitive clicking—If you listen attentively, you can hear a clicking sound when your heating and cooling system flips on and off. This is normal. However, if you’re hearing this sound again and again, you potentially need a heating and cooling service appointment to check if it’s an issue with the system’s relay or its electrical control.

You can prevent some of these noises from ever showing up by setting up normal maintenance appointments with Airtronic Heating & Cooling.
