Rated 2.6 out of 5 by 22 reviewers.
Rated 5 out of 5 by Easy install and beats expectations I have installed 4 of the 24" whole house fans in various homes and have always been hesitant in installing this fan due to the increased cost and poor reviews. At the insistence of my wife we decided to use this fan and if it didn't work we could easily install the full 24" fan. The house we live in is 101 years old and is lathe and plaster and after the framing out the hole the instillation was EASY. This unit is not silent but it is about 40% quieter than the 24" whole house fans without having to cut any joists. The fan works great and looks great. If you are looking for a QUIET solution for cooling, use AC, if you want a cost effective ambient cooling solution this fan is great and although it is not quiet it is more quiet than other comparable solutions June 29, 2014
Rated 5 out of 5 by Performs as advertised After reading a number of the reviews, I was a little worried about the quality and 'noise level' of this unit. The price was the determining factor and decided to go ahead and purchase. Installation was pretty easy! The instructions do not mention it, but I added some half inch weather stripping between the joist and the unit to help cut down on the noise. It worked out great! Don't get me wrong, it's not whisper quiet, but if you ask me, the noise level is acceptable. I live in the mid-West and have 4 levels in my 2,000 sq. ft. house. So, I don't have to tell you the temp difference from the bottom level to the top level! When the outside temp is cooler than inside, it takes about 30 minutes to drop the temp of the house down by 5-10 degrees on the top level of the house! Big difference! If you're debating on putting in a whole house fan, I seriously recommend you take a hard look at this product. Price is reasonable and quality is good. It was a great purchase for me! Definitely would recommend. May 6, 2014
Rated 4 out of 5 by it is louder than we expected It performs as desired but is much louder than expected. September 16, 2014
Rated 2 out of 5 by loud and wimpy This fan did not meet my expectations. I have a 1700 sq ft home and placed it in the hallway as instructed. The fan sounds like a hurricane and doesn't move enough air to cool the house even when it is 10 degrees cooler outside. The family hates it so much and it is so loud that we hardly use it anymore.

Rated 5 out of 5 by Tandem Whole House Fan I recently had a whisperaire whole house fan that was discontinued because of problems with the product. I really liked the size, remote control, and the fact you didn't have to do major reconstruction to install. When looking for a replacement I came across the Tandem Whole House Fan and read the 4 or 5 reviews available and was very discouraged. I asked my wife if she thought someone had a really good experience with a product if they would take the time to write a review or if it were only those with bad experiences. So, that is why I am here. We rolled the dice against all written reviews and purchased the tandem whole house fan. It fit in the hole left by my old fan, piece of cake, wired it up and pushed the remote waiting for the worst god awful noise in the world. Yes, it is a little loud but what whole house fan is not. It remminds me of the old box fans we put in the open window when I was a kid, a little hum and presto cool air. My wife and I absolutely LOVE this fan for a few reasons. Ease of installation and no major remodelling required to install. No major wiring nightmares to install a switch cause it is remotely operated. Turn it on high with a few windows open and it circulates cool air from outside through the house. We turn it on early in the morning with just our bedroom windows open and it gets down right chilly in our bedroom. We installed the unit in our central hallway and our house is about 1250 square feet it works as advertised. For me and mine this is a perfect fit and we are more than satisfied with its performance.
