How to Tell Your Heating and Cooling Service Provider What Sound Your System is Making Posted May 4, 2017 Your system has a set of sounds that it normally makes. For the most part, they should be easy to overlook on a day to day basis. If your system is making bizarre or disruptive sounds, you should call in a professional for a service visit.Listen carefully to the sounds you’re hearing, turn off your system and call in pros like Ilten's Incorporated. Your system may simply have a broken item inside. The noises could also be an indication that considerable repairs are necessary. If you know how to define the sounds your system is making, you can help your service technician figure out a solution.Here are some easy to identify sounds that signify 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 routine. However, if you hear this sound again and again, you probably need a heating and cooling service appointment to find out if it’s a problem with the system’s relay or its electrical control.Rattling, banging, clanking or thumping—Rattling usually indicates a loose piece.
