New furnace started kicking after a season of quiet
I had the 1920s furnace replaced (after asbestos removal) three years ago, and while it took quite a lot of work from our heating guy, it has been fairly quiet... this season being the best yet!
Then about two weeks ago it started kicking, and despite a few cleaning and treatments (silicone based treatment) by our heating guy, it hasn't changed the kicking one bit. About 5 minutes into the heating cycle when cool or cold, it has a few big bangs, then a big gurgle. All of this heard throughout the heating system, but from the basement it seems to be from the return pipe near the furnace. I am rereading the Lost Art of Steam Heating to refresh my memory, but any tips would be appreciated!
