When the furnace is on there is a loud low rumble coming from the vents on the other side of the house. Sounds like a train in the distance. So annoying! How can we muffle that?


First, you have to determine the source of the noise. Is it mechanical? Or is it air movement? Or is it the flames? Then perhaps it could be determined why it's only at one end of the house. Is it because that's a bedroom and it's quiet when you're in there? Is it why you only notice it there? This is what I would be checking to start.
