Lookingfor some sound advice from the experts that be out there.
We have recently installed two high efficiency Coleman (York) Furnaces in a large remodel. The vents are through the wall.
Our clients neighbor is complaining about the noise from the intake and exhaust from the power assistes vents.
Has anyone had this problem and has anyone found a solution that works?
Baffles? Extend the pipe lengths? Redirect the pipes through the roof? or into the ground?
One unit is in the attic and one is in the Basement.
Thanks

If you look at increasing the size of the exhaust you will reduce the pressurized sound? if that is the noise that is objectionable.
I've seen a lot of those units installed around here, and can't imagine anyone complaining about the noise from them (they're really pretty tame). Is there some situation that's creating the noise problem, like the intakes/exhausts being in a confined area, or the house next door being only 5' away or something? It may be that there's no "problem" at all, and therefore no solution- have you gone by to see how "noisy" they really are?

Thanks Bob-
They are not excessively noisy. Bt they do make noise. I am just doing my due diligence to help to defray a situation with their neighbor.
Maybe increase the run or add some bends to try to baffle or muffle the sound.
Thanks for the thoughts
Maybe a bend on the exhaust off to the left or right would direct the sound in a less-sensitive direction.If that doesn't make the neighbors happy, tell them you're going to replace the unit with an old Lennox Pulse.

You mean the old click pop tang tang unit
Sounds about like an old hopper cooled engine under load.

I'm no HVAC guy by any stretch but changeing the configuration of the in/outtake can change the way the furnace operates. Check into that before redirecting the pipes.

Tell your neighbor that her dog barks. Problem solved, he she will never speak to you again, rake thier leaves into your yard every fall, shovel snow infront of your drive way, leave a six inch unmoved swath of grass along the ajoining property line and if you mow that swath he will leave a six inche swath just beyond that, but other than that they won't speak to you. Ask me how I know. LOL!

Oh, did I mention the throwing of pine cones under your bushes?

tell the neighbors you'll give them a new furnace too, maybe that'll make'em happy...
Sheeesh
You didn't describe the detail of the discharge (the intake is not the noise maker).
I once installed a condensing furnace with a simple, straight pipe out the wall, and left it that way until I could finish the installation at a later date. Directly "in the path" of the exhaust discharge, the sound of the inducer fan could be heard 200 feet away. A pvc tee, with the run in the vertical is what I finally installed and cut the noise in half or better. A down-turned 90 elbow will help a great deal as well. Venting through the roof is probably the quietest option.
Tim- Thanks
We tried doing the 90 elbows. But I think we need to go up and away from the neighbor. The T option sounds interesting.
More a community relations thing than anything else.
Thanks for the advice.
You'd think someone would make a muffler for this situation, but a brief try at Googling something didn't find anything.

the furance manufacture would be the first place to look to for options and if a muffler could even be used.
The neighbor is complaining about your furnace? Get a new neighbor, keep the furnace. LOL! Just kidding, although it does seem odd.
My father once worked at a power plant and a lady complained about the noise coming from the plant. Well, if you know anything about power plant they are not exactly known to be noisy. My dad went to her house and heard absolutely nothing. She complained more. Others were sent. Then finally men with special measuring equipment who were able to measure a very low frequency sound which humans are supposedly unable to hear. Had something to do with a very large slow turning fan to move air through a cooling tower or something.
Sensitive hears?
