HVAC Blower Noise Problem
I have questions about our noise problem coming from our HVAC blower.
We have the return and air flow going straight into the blower (about 12 inches or so of duct work between the blower and return grill):
1. What angle should I have the sheet metal baffle? It seems as if this is the best fix.
2. What does the sheet metal baffle look like?
3. Is there a special noise reducing grill that we can purchase?
My HVAC contractor wants to charge me $750 to produce and install the sheet metal baffle to "greatly" reduce the noise. I have friends who can fabricate the sheet metal baffle if I give them more instructions, but we have no idea about HVAC and metal noise baffles.
Thanks in advance.
PS - the Blow is definitely the issue - its loud!
