International Comfort Products TCA042AKA1 Blower Wheel
The main blower wheel is a finned-type wheel that is used as to produce a steady airflow through a home. It can also be called a squirrel cage due to a funny semblance to that of a hamster wheel. However you decide to name it, it is a necessary part of a heating and cooling system that needs proper air pressure within the ductwork.
Warnings to watch for in a failing blower wheel cage
- If any one of the fins has been bent and it wobbles when spinning
- You detect less than usual air coming out of the vents
- A vibration can be heard when the system ramps up
