I have a broken fan. Can I replace just the blades or do I need to replace the whole fan?
If your fan hub is in good condition, you may be able to buy replacement fan blades, though we do not recommend aluminum replacement blades for balancing reasons. In order to achieve superior performance, you may want to consider buying a new fan that is professionally assembled and balanced.
