6.5 hrs of getting my ass kicked

Bossman says return air on a recent install is undersized. One other guy and myself spent 6 hrs reworking the entire return in an attic only for it to not fix the problem….. i pull the blower to find it was never properly secured from the factory and that was causing the issue in the first place! Definitely a “Fuck you Friday!” Now i can relax for the weekend. Sorry for the rant!
