As I was cleaning the 5th today, one of my items was to clean the filters. As I removed all 4 filters I checked the return duct and I could not get my fingers in the duct so went to Lowe’s and bought twelve 1” pvc couplers to install 3 in each return duct. Man what a difference in air flow, also 2 out of the 4 returns had a good part of the return not fully cut out so I opened them up like what
I have marked on this one.
