Recent Review: D & S is one of two authorized Casablanca repair companies in the area, and they also came recommended by a local dealer. It took a day to call back, but once he did, they scheduled service very quickly. The day the repair person came out, we ended up having an electrical problem having nothing to do with the fan or anything the repair person did, causing him to be unable to complete his work because no power was going to the unit. They did not charge us for this extra visit and told us to call when the whole-house electrical issue was resolved. We got the electrical issues resolved and called, and they were able to come back out within a week (they were waiting on a part). The repair was a little more expensive than anticipated (by $35) because the circuit board replacement required a newer wall control unit than what we had (fan was manufactured in 1997), but everything was done well and works fine. I would definitely use D & S again if we were to add a fan in another room.
