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 regularly makes. For the most part, they should go unnoticed. If your system is making strange or disruptive sounds, you should call in a certified technician for a service appointment.Listen carefully to the sounds you’re hearing, switch off your system and call in experts like Cytech Heating & Cooling. Your system may simply have a broken item inside. The noises could also be an indication that considerable repairs are needed. If you know how to define the sounds your system is making, you can help your service specialist figure out a solution.Here are some easy to identify sounds that imply a need for heating and cooling service:Repetitive clicking—You can hear a clicking sound when your system turns on and off, if you listen hard. This is normal. However, if you hear this sound frequently, you likely need a heating and cooling service appointment to check out if it’s a problem with the system’s relay or its electrical control.Rattling, banging, clanking or thumping—Rattling usually hints at a loose component.
