In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
There is a rattling sound that transfers up to the main floor coming from boiler area. I called a System 2000 authorized service and he came and heard it by the boiler and tried a few things. He could make it happen by banging on the pipe where the Spirovent is, and he heard it happen without doing anything. At first he thought it was a bad float inside the Spirovent, took out the float but problem remained. After a few hours and getting nowhere, I told him to call Energy Kinetics. The EK representative told him to wash out the boiler with TSP or vinegar because he's aware of such problems and it's scale, or at least that's what he thinks it is. Now, I have to pay for the procedure and there are no guarantees. Is there some other possible reason? What should I do?
