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. All in all, they should go unnoticed. If your system is making unusual or disruptive sounds, you likely need to call in an expert for a service visit.Listen hard to the sounds you’re hearing, switch off your system and call in pros like MPC Heating & Cooling. Your system could simply have a disconnected piece. The noises could also be an indication that considerable repairs are necessary. If you know how to talk about the sounds your system is making, you can help your service professional create a solution.Here are some common sounds that indicate 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 well. This is routine. However, if you hear this sound repeatedly, 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 part.
