Hello -
I just had a new furnace installed. The blower is horribly loud. There is no way that I can live with this noise, but the installer said that's how all of the high-efficiency furnaces are now. I really don't believe anyone would put up with this.
Is there anything that can be done to reduce the blower noise on a furnace? Assuming that it was installed correctly, that is. I wasn't able to find much in a google search of groups.
Thanks for any info -

Is it blower noise from the air whooshing through the ducts, or something from forced air induction of the burner. My neighbor has some sort of (modulating?) high efficiency furnace with PVC inlet/outlet on the side of their house, that in the dead of the night, I first thought was somebody casing the neighborhood (sounds like a V8 engine on fast idle). If I can hear it from next door (across a double lot), I cannot imagine how noisy it must be in their house (they do say it is noisy).
I have an older home with single pipe steam heat which is relatively quiet.
I am not (repeat "not") a HVAC expert, but the HE furnace on my old house was intolerably loud. I was able to cut the noise by half by gluing wood to the ducts. It damped the vibrations significantly. It was still noisy, but at least I could live with it. The house is still there 12 years later, so it didn't start a fire!
The one I just put in my new house isn't bad at all; so obviously it isn't "all" of them.
Is it just at startup or all the time? One of my 3 gas furnaces was very loud at startup. I thought it was the attic one and it was just noise going thru the sheetrock ceiling and nothing could be done.. After 2 years of that, I'm in the basement and the noisy one starts off like a roar. Turned out the source was the basement and the gas pipe was close to a PVC exhaust pipe and that vibrated against the PVC when the thing started up creating a roar throughout the house. A sponge between the 2 solved the problem forever.
that's how
I have a very similar situation. The noise occurs while the furnace is running (the noise of a fan sucking air though the intake vents).
