We had a fan, 11 years old, that we loved and started making noise. We could have replaced it since it had a lifetime warranty, but it was discontinued and we didn't like any of the choices we had. Our Lighting guy recommended Fan Doctor. He was knowledgeable and friendly. He replaced the bearings in about a week, recommended a change in the way we used it, and it is back up working perfectly. He did everything we expected and more.
