My upstairs zone is one long continuous above-floor run. It has 3/4" copper return tubing resting on return tubing brackets above the fins. When the return tubing heats or cools it causes the brackets to "ping" a little bit as the friction between the return tubing and the brackets is finally overwhelmed by the tension of the expansion/contraction of the tubing. The front covers are attached to these same brackets, and these "pings" get transferred to the covers and cause them to make noise.
I doubt I am the first person to experience this problem. Does anyone know of a good remedy?
