Product Reviews

Rated 5 out of 5 by from Much less expensive than fan motor alone If anybody ever needs a replacement fan motor for one of these just order the whole product it is much cheaper than the fan motor ordered by itself.

Rated 1 out of 5 by from Jet engine is quieter I HATE this fan. It's a cheap, noisy fan that has higher decibels than a jet engine. I didn't buy one by choice; rather, the contractor who built my house put them in, and I hate them - so much that I'm considering an expensive retrofit to replace them with Panasonics, which rock - very very quiet and better performing.

Rated 5 out of 5 by from Replaced an older fan of the same size and type. I bought two fans to replace the others that were about 10 years old. This fan was the same size and configured like the other fans and it went right in the same place. I shopped around and found to have the best pricing so I ordered them. I am very satisfied with the service from and will check back again in the future before my next purchase. Thanks.

Rated 5 out of 5 by from Good fit The fan arrived promptly and fit exactly where the old, dead fan had been. This was a "repair", not new construction. Corrosion and a bad bearing refused to allow the old fan to start.

Rated 5 out of 5 by from good replacement Our old exhaust fan was making a lot of noise.. found the exact replacement through Acturally, all I had to do was take out the fan and motor from the new unit and snap it in place of the old and left the houseing portion in the ceiling.. worked out great and only took me a few minutes to do..
