How can I reduce the noise from an air handler unit?
I have a Goodman AR42-1 air handler unit in an open closet. The setup looks like this:
When the air handler activates it sounds like this:
Current sound levels:
Everything off: 36 dB A/C on and inside closet: 63 dB A/C on with door closed: 59 dB A/C on in Living Room: 55 dB
How do I reduce the noise from my forced air furnace? - recommends lining ducts with fiberglass
Is there any way to make my furnace quieter without replacing - recommends 1/2" rubber attached to the blower.
Home Soundproofing- recommends replacing a part of the duct with sound absorbing flexible duct or replacing a 6" section of the plenum with a rubber boot.
sound reduction in a condo HVAC closet - reduced fan speed, covered door except for vent with 1/2" of homastate.
