International Comfort Products NAC236AKA1 Blower Wheel
A blower wheel is a finned wheel that is used to produce an airflow throughout all the ducts. It is also referred to as a squirrel cage because of its remarkable similarity of an oversized wheel a hamster might run on. Regardless of what you call it, it is still a very necessary device of any HVAC system that needs proper air circulation.
Major indications that your blower wheel is in need of replacing
- You notice less than normal air going through the vents
- If one of the fins has been bent and looks unbalanced when it spins
- A weird sound is audible when the system starts
