Question: Downrod needed for Vaulted ceiling, description says "Not compatible with Hunter Original down rods." Say what? Hunter isn't compatible w/ Hunter???
Document: I purchased 3 of these fans and 3 - 24" down rods for my vaulted ceiling living room. It took my electrician about 3 hrs 45 minutes to take the old fans down and install the new Hunters.The fans are staying on the low speed which gives enough breeze for a nice cooling effect.
The rotation direction is reversible, so in the winter you set the fan to move warm air down from the ceiling, and in the summer you reverse it and draw cool air up from the floor. In hot climates the fan can be used at the higher speeds to move a lot of air quickly. I can't think of another product that has impressed me more than Hunter fans, given their performance and the amazing service, which was needed only once in 38 years.
Hunter, its all that's in my house!. I have 7 Hunters throughout my home. One in a high vaulted ceiling, has been running 24-7 for 11 years except to be cleaned. We decided to install yet another. So we went to Lowes, shopped and my wife said, before you buy, check amazon. This Great Fan arrived within 4 days. and it looks and works as well as the other 7 Hunters. Thanks again amazon, you saved me $125.00.
I really had no idea which brands are good or bad, or better/worse than others, but I have to say, after this purchase... I will either get this same exact fan again, or will look for another Hunter product.
This fan does not contain &#34;brain&#34; for remote. I purchased a hunter remote separately because I was lead to understand that this fan was &#34;remote compatible&#34;.
I didn't bother using their balancing kit. The highest speed is quite a blow and I don't need but the two lower speeds for bedroom.Packed with both a standard and a short downrod, the standard rod was perfect for our 8' ceiling as it deployed the fan blades the required 7' off the floor.Installation guide, diagrams and parts list are great. Packed well.Overall fair value at $100.
It's always a bit challenging to put up a ceiling fan, but while standing w/one foot on a bed aand another on a step ladder is something I wouldn't recommend! My fan was missing one of the rubber pads that mount on the ceiling, but I formulated a replacement easy enough.Beyond that the directions were very easy to follow and understand and the blades were perfectly balance when I finished. It's a very quiet fan, perfect for in the bedroom.
These fans are what they say they are and great for the money. East to install, and provide the circulation expected.
The Hunter 53091 is an economically priced ceiling fan. While it was a little time consuming to install, it has an attractive look and operates flawlessly.
Bought 6, went up as usual for ceiling fans (tedious), and they look great! Would recommend the Hunter as a good deal!
