Question: How do I get warranty service?  Fan is seizing up first unit I have had this problem with and it's a few months old
Document: Had to get a replacement for the first one, as when we opened it, it didn't work. The replacement worked, but when on low or medium speeds and pointing parallel (+/- 30) to the ground there is a whining noise. We're using it to blow straight up, so I am letting it go (plus customer service was excellent).I was originally looking for a replacement to an old Patton fan. If this did not have the loud noise, it would have been.
I bought this fan 3 months ago. It's been very hot in Chicago, well over seasonal norms, and I only ran the AC 3 weeks in the last 3 months, this little guy makes a nice cool breeze and does it without a sound (from 8 feet away) I work and sleep comfortably with a room temp of up to 85F with this on (when it gets over 95F, I close the windows and turn on the AC).
It gets the job done in a way , I read all the reviews and I wazz expecting much more power but for the size of this fan " little" it's pretty good but if your the type of person that gets hot when sleeping I will strongly recommend to get a biger one
I was looking for quality and I found it. YOu can pay alot less for a fan -- but you'll get junk. This is a well made fan with a great deal of power, yet it is unexpectedly quiet. I suspect that this fan will serve us well for many years to come.
It's a solid built fan and heavy for the size but the weight enhances the main problem that it has. I live in a wood house with wood floors and no matter if it's running on low, med, or high speed there is a strong vibration emitted that can be felt through the floor anywhere in the room. I guess the positive of that is I have a vibrating chair when I'm sitting in the same room when it is running.
There was a problem with Fedex delivering my Air King fan (see earlier review), that apparently got lost somehow. I really appreciated the way that Amazon and Air and Water resolved this issue by stepping up to the plate, and sending me a replacement of which I am thoroughly enjoying at this moment. I want to thank you for all the efforts put forth by both parties in resolving this matter.
This was chosen due to it's classification of industrial grade and a need of operation 24/7 during the summer months starting next year. It was test run for a couple of days and seemed to work fine. The reason we gave it only three stars is due to the fact that out of the box the paint was peeling  on the support frame and the fan shroud. After sanding the rust off and the edges of the peeling paint, a little paint made it look like a new fan. Thank you.
I ranked three stars as I imagine it was just the fans I got, and not all of the fans of this type. Make sure the company you buy from has a good return/exchange policy in case you get a junker also.
Saves me money! I am truely impressed with this fan and would not hesitate to buy another if need be.
This fan has a lot of power but runs quietly. No regrets. I use it after showers to dry the steam in the bathroom and use it on carpets after shampooing them.
Answer: I had this happen to mine as well, but it happened straight out of the box!  I contacted the company through Amazon and they sent a replacement, which worked for a year, then the same thing happened, but this time it was out of warranty so there was nothing left to do but replace it, with a Vornado.  No problems with that one.It's a shame, I wish Air King's quality was better. The fan is the style I want, but I would not suggest buying one after the two I had failed so miserably.
