Maxx Air Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. This electric fan's low vibration direct drive design and galvanized steel fan assembly contribute to a quiet, efficient performance alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your home's ceiling. Install in a joist-in or joist-out configuration and control the fan from anywhere in your home from your smart device. Whole house fans offer an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through the attic exhaust vents to create a cool and comfortable living environment. Save on energy costs by taking advantage of the timer setting available only on Wi-Fi hub smart fans, which will automatically turn your fan off after your desired time setting has been reached.

This is a monster of a fan and it really does a great job getting the hot air out of your house at the end of a day. I have a 1920's craftsman house in coastal California and the insulation in the walls is non-existent. Keeping everything shut tight during the day holds back the worst of the heat during the day but when the evening cools down you can still swelter inside. Open a few windows and this fan quickly pulls all the air out of the house and pushes it out through the attic. The temperature drops quickly and the breeze is awesome.
Installation for me was super easy because I lucked out and there was already a perfectly sized extra attic access. Cutting the framing doesn't look that hard but in my case I just had to mount the fan. I followed the suggestions to minimize the noise by building it up on a frame above the joists and that took minimal effort. Wiring was straight forward and I got everything up and running within a few hours.
I did have one issue where the louvers weren't properly closing after the fan turned off. I had to bend the mechanism a bit but now it seats properly.
My only complaint about the features was the Wifi module in the fan. Despite what the instructions seem to indicate and what another reviewer posted, I could only get the Wifi to work as a stand alone network. No matter what I tried I could not get the fan to join my existing network. I tried contacting the company by email but go no response to my support request. Ultimately that means every time I want to activate the fan I need to switch my iPhone from my normal Wifi network over to the adhoc network for the fan. It's a hassle and negates most of the value of having the fan be network connected. I'm taking off a star as a result.

WiFi fan that can only be controlled by Wifi and no alternative controls - great addition to the "smart" home.
This took about eight hours to install on my own in my attic. Those eight hours were completely worth it. My house is much, much cooler so far, and it’s been hitting nearly 80 every day since the install.
There was nothing technically difficult about this installation.
The tools I used:
Cordless Drill (I used a 5/16” bit for the shutter screws, in addition to a 5/16” hex driver and a Philips driver for securing some plywood boards in the attic), flat head screw driver, permanent marker, pencil, pliers, pneumatic nail gun (with 2” nails), hammer, miter saw, measuring tap, hand saw, jig saw (for a couple of slightly more complex cuts to some 2x4’s that had to fit oddly over existing 2x4’s), saw horses, extension cords, silicone caulk, drywall saw, utility knife, tin snips, crescent wrench, two ladders (one 3’, and one 6’), shop vacuum, broom, mop and probably a few other things I forgot about.
In addition to the tools, there was also a couple of flashlights and work lamps, respirator, safety glasses, gloves and duct tape to keep insulation from getting into my shoes and up my pants. I have blown-in insulation that has sat for 30 years. While initially stiff, once disturbed it just gets everywhere. The point I’m trying to make is that you’re going to need 2 to 3 times the amount of tools that the instructions say you need.
The first step is finding a location. I really only had one choice as I live in a tri level house. This location is such that I couldn’t exactly comply with the instructions. The instructions specify that you must place the fan in a location so that it sits directly over a joist. However, the only location that I could place the fan was not in a location that allowed this. Instead, my joist was off-center by several inches. In the picture of my installed shutter, you’ll see that one shutter on the left does not open. That’s where the joist is. The hallway location for the fan was only 35” wide, and the joist was 11” off from center. Given that, I did have to slightly modify the shutter for my situation. Why would the manufacturer assume that a fan can be installed on center to a joist in every home? The shutter has small cut outs to fit around a joist. I had to create a second pair of cut outs to meet my needs.
Up in the attic framing a box for the fan to sit on was fairly easy. While this did require a dozen cuts on the miter saw (measure twice, cut once, especially when you have to have to haul the lumber up two flights of stairs, then up a ladder into an 90F degree attic!), the work was simple enough. Once the box is framed in, the instructions say to lay 2x6’s on top for the fan to sit on. Again, very easy.
The instructions did say to cut the hole in the drywall… and then frame it in. Since I have blown-insulation, I did this slightly backwards so that I could avoid a massive amount of insulation falling down into my hallway. I drilled a hole in corner of the area to cut out, then went up in the attic and dry-fit my lumber. Once there, I proceeded to cut the hole out. When the hole was cut, I nailed in the wood and was ready for the next step.
Getting the fan in the attic was arguably the most difficult part of this task. My attic access is in a small bedroom closet and measures 22” x 15”. The fan is 28.5” (roughly) on a side and 8” wide (if you take the fan blade off). The only way I was able to get the fan into the attic was by carefully making the hole in the ceiling just a fraction of inch wider, then lifting the fan at an angle up through this hole. This allowed for an uncomfortably small margin of error, because the vent is only an inch or so wider than the hole needed to be to allow the fan to pass through (measure twice, cut once!). It mostly required brute strength, but aside from disassembling the fan, or cutting a massive hole in the side of my house on the exterior, this was my only option.
With the fan in the attic, the instructions say to attach it to the 2x6’s. They do not say how. I chose to use a few strips of scrap, nailing them to the fan and then to the 2x6’s. This worked well. I got it wired up (it has wiring harnesses for hot and common wires and a ground screw). One thing I would suggest is to test out the fan before you install it.
Once the shutter was in place and everything was caulked up (to create an airtight seal, per the instructions), I powered it on.
The fan loses a star for control. There are only two ways to control this fan. With a button on the control box (wired to the fan motor with a very short cable) or with your smart device. That’s it. So either you climb into the attic to push the button (on or off) or you use the app (named Wi-Fan). The app allows for two speeds (it defaults to three, but the fan only does two) and timer control. I had some difficulty pairing the fan into my home wifi network (this is important so the 1. the fan can be controlled by multiple devices, and 2. you don't have to disconnect from the internet to control the fan). The customer support was very helpful. There is an FAQ in the app which explains this step by step.
Still, I wish there was a simple on-off button--why didn't they put the on/off button on the bottom of the fan, instead of the top? That way it would be in the shutter and wouldn't require going up into the attic. This to me is a fatal design flaw because not everyone will have a smart device, or be savvy enough in operating such device, and sometimes people don't want to mess with troubleshooting especially if it's hot out and they just want to turn the fan on. There aren't any unused wires in the box either -- I mean, at least the option to purchase my own remote or wired-in control and connect it to the fan would be great. This is a fantastic idea, especially as the "smart home" trend is on the up and up -- but I still think a design is lacking if simple controls are removed.
I had to replace my whole house fan. I am a techy and seen this supported wireless so spent the extra on this. Was probably a horrible mistake. The Wifi wont connect to anything standard today, it's basically wpa or wep and doesn't support wpa2. I worked around this limitation by opening up my network and continue to have problems. The controller will either not respond for long periods of time on multiple phones or it will factory reset itself automatically an random times so you have to go through the setup again. I'm about to tear the hub off and wire it to a switch. Aside from that the fan itself and the louvers are working fine.

Has been installed for a couple of weeks now and we've had several 90+ days. Works like a charm keeping the house and garage cool all night after only running it for an hour before bedtime and sometimes an hour in the morning. Had a professional install it and glad I did. He did a great job that took about 3 hours. I'm no electrician or carpenter so it was money well spent. like others I agree that the WiFi is terrific but it isn't integrated into the house system so a few extra steps on the iPhone to turn it on and off or change speeds. I highly recommend this product and hope that it lasts for years to come. Quiet, powerful and nice looking.

I installed this fan in early fall when the attic temps weren't so hot and I didn't mind spending a few hours up there. I've had several months of use and the only option I'd love to see added is a manual switch. You can only control the fan through the app on your phone, but I'm sure many people would appreciate the option to add a manual wall switch as well. You may be able to wire one in yourself, but be aware this will void any warranty.
I own a 1,200sf ranch with a finished and insulated basement and have been very happy with how this fan, installed in a large first floor closet, allows me to circulate the stale basement air out of the house. It's just the right size for my home, and the controls are very simple. But as it is I enjoy the circulation this fan provides, and installation wasn't nearly as hard as expected. Plan on several hours, but if your home is built with standard rafter width then the install should be pretty straightforward. It also helps that I already had a dedicated line available in the attic from lights that were never installed.
All in all I'm very happy and am hoping for years of use from this fan.

This was definitely worth it and I am super happy with this fan! We received this a while ago but it has taken a long time to get my husband willing to spend the day to install it. It took him with a small amount of help from me about half a day maybe a bit more to install this but worth every bit of it. The installation instructions were real good but we had space issues to deal with and the heat of summer as well. We have been told by multiple people to get an attic fan to help with the a/c issues in a few rooms in the upstairs of our home. We waited longer than we should have due to price but now that we have this working I am super impressed. I really love the ability to control with wifi. The whole house actually feels much better now that this is in use. I wish we would have gotten this a lot sooner. Great smart product that will keep you whole house cooler, my home is almost 3000 square feet and works well through the whole house.
