Short instructional segment explaining how indoor HVAC blower components (blower motor and blower wheel/squirrel cage) move air in a house and how dirt/dust buildup on the blower wheel’s fins flattens them, reducing airflow effectiveness. The speaker describes the wheel’s cup-like fins and the mechanical consequence of contamination on air delivery.
Another thing is when you have a dirty unit, a dirty indoor blower motor and a dirty wheel. See what happens when you have the blower motor, which pushes the air in the house, right? So it pushes the air in the house and uses what's called, we call a squirrel cage, but it's a blower wheel that actually pushes the air in. So if you look at the blower wheel, it's kind of like a cup. It has all these little fins on it all around the circle. And it's taking air and it's throwing it and it's pushing it. Alright, it's pushing it in the house. So when that becomes dirty, when you have a dirt and a dust build up on it, it becomes flattened. So now you're trying to push air like this. Obviously not as effective as the cup, Right? So one thing to look at is.
