We’ve talked about the bad venting set up for this furnace and water heater and also about what it sits on in past posts. I’m not quite done with indoor air quality, and I’d like to draw your attention to another area of the duct work that is right out in the open.
While we look at this system in the garage, you can see that there was an attempt to insulate and to seal the duct work. The un-faced fiberglass wrapped around most of the duct work is stained in a number of places. This would be from the garage air being drawn into the system every time it runs. The mystery regarding duct tape is why we call it that, since it doesn’t seal ducts and It was on parts of this system.
Keep in mind that all of the observations were just from the garage, the area of the home you may walk through every day. Never mind what we found in the attic.
The happy ending to this story is that this homeowner was given a list of solutions to the problems we found. With a new system, measures were taken in the home as well that will mean lower energy bills, better comfort, and most important of all a healthier and safer home.
