Arrived due to stuff coming out of the registers when the air is on. Checked and verified all duct work and system is sealed off. There is not entry points sucking any of the dirt/ insulation from attic into the system to blow out. What’s coming out of the registers seems as though it was from the change out. Debri got into supply and is blowing into the home. Set up a duct cleaning for thurs. client will pay at completion of duct cleaning. *** please call client when otw!*** ***please use front door***
