What should be done to repair a noisy metal supply register with bent vanes?

To address the issue of a noisy metal supply register with bent vanes, the most effective solution is to consider that the entire register may need to be replaced. When vanes are bent, it can significantly disrupt airflow, leading to noise and inefficiency in the heating or cooling system. Bent vanes may not realign properly or function as intended, which can result in continued noise and improper air distribution.

Replacing the entire register ensures that the new unit functions optimally, promoting better air circulation and reducing or eliminating the noise. In some cases, attempting to repair the vanes may only offer a temporary fix and could lead to further complications down the line. This approach guarantees a more permanent solution, ultimately supporting the effective operation of the HVAC system.
