I have a relatively new Energy Star Triangle Tube furnace--efficient enough the exhaust pipe is a 6" inch PVC pipe. Or is it 4" inches? Hot water radiator system.
I had a spurting overflow valve problem a few months ago--that this forum helped me to diagnose and correct. Now I want to fix another problem. One that's been there from the getgo.
Everything now works well except one remaining problem. This furnace makes a trombone like roaring note when it starts up, that the neighbors are complaining about. Sounds a bit like a harmonic note from a guitar, crossed with a tuba.
Is this because of some odd frequency to an internal fan? Or what? Can it be fixed? My plumber has gone out of business and disappeared.
