How to Tell Your Heating and Cooling Service Provider What Sound Your System is Making Posted May 4, 2017 Your system has a collection of sounds that it normally makes. For the most part, they should go unnoticed. If your system is making strange or disruptive sounds, you likely need to call in a professional for a service session.Listen carefully to the sounds you’re hearing, turn off your system and call in experts like Brooks Heating and Air Conditioning. Your system may simply have a broken item inside. The noises could also be an indication that larger repairs are necessary. If you know how to define the sounds your system is making, you can help your service specialist work out a solution.Here are some easy to identify sounds that imply a need for heating and cooling service:Repeated clicking—You can hear a clicking sound when your system turns on and off, if you listen hard. This is natural. However, if you hear this sound repeatedly, you definitely need a heating and cooling service appointment to determine if it’s a problem with the system’s relay or its electrical control.Rattling, banging, clanking or thumping—Rattling usually indicates a loose part. Strong banging or thumping sounds could mean a component of your system is totally broken or disconnected. Normal maintenance can prevent some of these noises from ever starting.
