I send a text message and no reply: I need all that on that list complete. The duct work is improperly installed and wasnt what I was promised. I was told that it would be all metal not that cheap flex crap! Manufactures install specification say NO 180 DEGREE BEND. No more than a 2 sag. NO KINKS IN RUN. Hanger supports are too far apart. They left all the old hangers. They didnt clean up. User's recommendation: *** NO go Reem.
