Why Duct Loss Effects House Efficiency

Video Transcript

Hi! My name is Joshua Lindsey with CFM Building Science Solutions. On behalf of Expert Village, we are going to do a duct test in this house. I want to tell you why in two different ways. Number one, if your unit is in the garage and the holes are on the return side; remember when we talked about the return sides bringing air into the unit. Okay if you have holes that are down there in the return side of your unit and your unit is in the garage, think about it. You are sucking whatever fumes you might have in the garage. You are sucking them right into your unit so you really need to think about those holes. You could be sucking gas fumes, you could be sucking whatever the crazy things that people store in their garage. They will be sucking that right into their air conditioning unit and putting it out in houses. We've done tested multiple houses where people always have headaches or some kind of sickness going on. They are trying to figure out why and that is the reason. Because they've got problems in their air conditioning unit right in the garage.
