Bryant 478 Blower Wheel
The blower wheel is the primary device that is used to provide forced air through a home. Once in a while it is also called a squirrel cage because of the noticeable resemblance of a rather large hamster wheel. Regardless of what you call it, it is definitely an important aspect of an air handling system that calls for a good amount of airflow.
Symptoms that the main blower wheel will eventually need to be replaced
- If a piece of the cage has broken off and looks unbalanced when it spins
- Grinding sound is noticed as the system begins
- You see much less airflow lately
