International Comfort Products PAF042K000A Blower Wheel
The blower wheel usually has fins all around it and it is spun around by a motor to produce an airflow throughout all the ductwork of a home. It is occasionally called a squirrel cage due to the understandable resemblance of an oversized wheel a hamster might run on. Whatever you want to call it, it is still a very necessary contraption of any system that needs proper airflow.
Important clues of an unhealthy blower wheel assembly
- You detect much less airflow lately
- If one of the fins has been twisted and looks unbalanced when it spins
- Clanking sound is audible as the HVAC system starts up
