Welcome! Here are some tips for using this forum.
hey everyone i installed a new 100,000 btu 95% warm air furnace new duct
work supply and return....everything operates fine, except for the
return duct is very loud...furnace is in basement and return duct goes
straight up 10 feet to first floor into a return box....it is NOT a AIR
FLOW ISSUE, temp rise is fine and if i take the blower door off to allow
maxinum air to go through system i still have the noisy return. the
noise just sounds like the blower wheel & motor running....is there a
way to reduce the noise with running the return duct a certain way or
is there such thing as noise reduction ductwork for example if i get
ductwork thats insulated inside it??? any help would be greatly
appreciated thanks paul s
