If your system is making strange or disruptive sounds, you probably have to call in a professional for a service session.Listen carefully to the sounds you’re hearing, switch off your system and call in professionals like O'Brien Heating & Air Conditioning. Your system may simply have a disconnected part. The noises could also be an signal that considerable repairs are necessary. If you know how to talk about the sounds your system is making, you can help your service professional work out a solution.Here are some easy to identify sounds that signify a need for heating and cooling service:Continual 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 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 means a loose part.
