Panasonic whisper quiet fan not quiet anyone know why?
Hi everyone, I purchase a Panasonic whisper quiet fan and it is louder than my nutone fan. I cannot figure out why. Someone told me that I should insulate my duct work. I currently have uninsulated duct work that goes up into the attic and runs approx. 5 feet and is vented outside thru the soffit. Anyone have any idea why it would be loud?? This fan cost nearly $200 and I am very disappointed.
