What is the grill dimensions?

What is the grill dimensions?
Asked by: David
25 1/2" x 16 3/4" -- just a couple inches bigger than the required hole in the ceiling. It is designed to fit between joists, either 16" or 24", so you mount it either lengthwise or widthwise without cutting any wood; only drywall.

1600 CFM Tandem Whole House Fan is rated 2.7 out of 5 by 39.
Rated 5 out of 5 by from Great fan for the price If you want a quiet fan, you need to be willing to spend more money. For under $500, this fan works great. You need to open windows for this to work. I feel like everyone on here who complains either doesn't know how a whole house fan works, or they're super impatient. It takes about 30-60 minutes to cool the house off completely once it's cool outside. I always rotate which windows are open. I start by opening the windows that the sun is no longer hitting. When the sun is down, I switch which windows are open. This fan was super easy to install. I love that it has a remote, so I didn't install a switch. I can always install one late if I lose my remote. :)

The first unit that was shipped to us was defective and I had to call the online number and then return it to the store which was a hassle. The re-order was confusing, but finally a week later the 2nd one arrived at the store and I went and picked it up and we had it professionally installed. That evening we couldn't wait to turn it on!!! What a disappointment! Hardly any air movement and the temp in the house went down only 2-3 degrees. I only cracked windows as suggested and still no luck cooling the house down. I have better luck cooling down the house by opening all the windows and doors. The fan is noisy, but that wouldn't bother me at all if it worked as it claims. Out the money for the unit, plus $100 for the installer. I don't recommend this at all.

Rated 1 out of 5 by from Did not work as it should My husband decided to wire up the fan before installing it up in the attic and we are glad he did! The fan did not work correctly at all. The automatic door stayed shut while the fan was running and when the fan shut off then the door would open. That is the exact opposite of what it is supposed to do. We returned it the next day.

Rated 4 out of 5 by from Whole House Fan Installation The installation worked out just as the instructions indicated, pretty easy. It worked just as described. It isn't silent but it is a whole house fan. I wouldn't put it in my living room but it works great on the second floor of our house. The remote works great.

Rated 4 out of 5 by from Works GREAT, but is LOUD It works wonderfully, but it is LOUD, even with only one of the two fans on. Just know this before you purchase.

Rated 5 out of 5 by from 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

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Excellent product in use for 7 years! Purchased this product in May 2007 and installed it myself. Easy and relatively quick. Yes, it is a bit noisy, but we run a fan in our bedroom at night to cover up outside suburban noise anyway, so the unit does two jobs for us. It moves lots of air. The trick: only open windows a couple of inches in each primary room. If you open ALL the windows, you will not feel the air moving. Only issue is the remote is wearing out from frequent use. Where do I get a new remote? Would buy another of these units without a second thought.
