The projects seem to never end.. :laughing:
Basically long story short, I replaced a couple bathroom fans on my top floor bathrooms, and they vent to the attic soffits. The fans I changed were the cheap/noisy ones and replaced them with 80cfm quiet fans w/ 4" outlets. However, the original fans only had 3" ducting, that each run approx. 12-15' to the soffits. When I originally installed these fans I just used 4"->3" reducers, but now I'm contemplating whether it's worth just buying new 4" ducting and running new 4" duct for each fan and install new soffit vents. Any thoughts?
Reason why I'm finally thinking about running the new ducting is I'm looking to install soffit insulation baffles and add about 10" of insulation to make things a little more comfy in the house. Now would definitely be the time to replace the ducting if I'm going to do it..
So is it worth upgrading the ducting to 4" or am I just making more work for myself? Thanks!
