International Comfort Products TCH242AKA1 Blower Wheel
The main blower wheel usually has fins all around it and it is traditionally used to produce an airflow throughout a house. It is sometimes called a squirrel cage due to the similarity to that of a wheel that a pet hamster may use for exercise. No matter what you call it, it is definitely an important piece of equipment of any heating or cooling systems that requires proper air circulation.
Chief elements to watch for in a failing blower wheel cage
- If a little piece of a fin has been bent and it wobbles when spinning
- Grinding noise heard as the HVAC system starts up
- You find quite a bit less airflow coming out of the system
