packaged unit noise and vibration reduction

Postby clueless » Sun Dec 05, 2010 8:23 pm

I have two packaged units for my house. One is right outside the guest bedroom. Guests have let me know that it's very loud. It even bothers me at night. Although the unit itself is loud, the bigger problem seems to be more from the vibration of the sheet metal ductwork that runs between the unit and the house. Is there some kind of rubber coupler that would dampen the vibrations? And if so, approximately how much would it cost to add one after the fact?

Can you give me a couple of suggestions? I'd like to be somewhat informed when I call around.

You can use flex duct, coming from the unit to the hard duct under the house, maybe 4-5' peice, you need to measure ductwork going under house and buy flexduct accordingly. Remove a section of hard duct and replace with flex.
