Upon arrival, homeowner informed me that right before he bought the house there was a big plumbing flood issue and that the restoration company took care of it before he bought it. Except for the air flow issues throughout home. I think that he thought that they fixed duct work during renovation 4 years ago. He informed me that there are hot/cold spots throughout the home and also lack of air flow! Started furnace in heat and checked static pressure on supply side .18" & return side reading .68" w.c. Which then Explained to him what static pressure means for comfort through out his home, efficiency and longevity of equipment. Found return was undersized at 16" duct but in OK condition. Went under home and found 4 ducts not even connected and insulation/liner was not even on just hanging. Found sagging ducts with dirt and debris. Refer to estimate!
