What is the best method of repair for a noisy residential supply diffuser due to a loose vane?

• A. Tighten the vane
• B. Replace the diffuser
• C. Adjust the airflow
• D. Clean the diffuser

Answer: (B)

Choosing to replace the diffuser for handling a noisy supply diffuser caused by a loose vane is often seen as an overreaction to a fixable issue. The proper repair method for a loose vane in a supply diffuser is to tighten the vane. This action directly addresses the root of the noise problem, which is the looseness causing vibration or rattling sounds. Tightening the vane stabilizes it, reducing or eliminating the noise effectively. While replacing the entire diffuser might address the noise, it is not necessary if the issue can be resolved with a simple adjustment. Adjusting airflow and cleaning the diffuser may also be relevant maintenance practices, but they do not directly address the issue of the noise caused by a loose vane. Thus, tightening the vane is the most efficient and targeted method of repair in this scenario.
