Whynter ARC-12SDH Blower Wheel
The main blower wheel is commonly finned and is traditionally used to generate airflow throughout an entire home. Once in a while it is also called a squirrel cage due to the slight similarity to that of an oversized hamster exercise wheel. Regardless of what you call it, it is definitely an important contraption of a heating and cooling system that needs a good amount of airflow.
Major indications blower wheel assembly will soon need to be replaced
- If any one of the fins has been dented and it seems out of balance
- Grinding sound is audible as the HVAC system starts up
- You see a lot less than usual air coming from the vents
