Lennox HPXB15-042 Blower Wheel
The primary blower wheel is finned and is used in order to produce a steady airflow through all the ductwork of a home. Once in a while it is also called a squirrel cage due to the understandable likeness of a very large wheel a hamster would run on. Regardless of what you call it, it is still a crucial device of any HVAC system that needs proper airflow.
Signals your blower wheel is going out
- If any of the fins has been damaged and does not spin right
- Scraping sound can be heard when the system ramps up
- You discover less than usual air coming from the vents
