Product Overview

Maxx Air Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. Our belt drive ventilation fans have been engineered to offer a superior performance with a more stable motor mount that is stronger than typical tube-style bracing and virtually eliminates vibration alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your home's ceiling. Install this electric fan in a joist-in or joist-out configuration. 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 for a cool and comfortable living environment.
  • Designed for houses with 2,000 - 3,000 sq. ft. attics
  • Steel construction, aluminum fan blade assembly, and dual ball bearing technology with automatic shutter
  • Joist-in or joist-out installation; for ceiling install only - not for wall exhaust use
  • 2-speed operation with included dual high/low and on/off wall switch; moves 4,160 low / 5,950 high CFM
  • Requires 10 - 12 sq. ft. (1,440 to 1,728 sq. in.) of NFA

This fan moves a ton of air! Works great. Glad we put it at the back of the home, it's a little loud, sort of sounds like you are running the washer or dryer. We actually have had to turn if off because the house has gotten too cold. I keep an eye on the outside temperature and as soon as it is nice, I turn off the AC and we use the fan. Anticipated big summer savings.

Installed this fan as instructed and within 30 seconds of running several nuts came lose motor started making noise. Went back up to super hot attic and tightened everything i could find. The pulley wheel on the motor was also lose. Tightened up everything and ran the SUPER LOUD FAN for about an hour. As i was standing under the fan put it on high and the entire blade fell off like another review and completely destroyed the shutters. So taking this piece of junk out of the attic and have a big 26x28 patch job to do now. PLEASE DO NOT WASTE YOUR TIME OR MONEY ON THIS. YOU WILL REGRET IT. I GUARANTEE IT

    It's pretty straight forward as far as installation and wiring. (I recommend watching a few different videos online before starting. Maybe Home Depot could make their own installation video.) Once I got the hole cut and the framing prepared, it went in easily. The unit is a little noisy, but it works great.

    LOW SPEED DOES NOT WORK AT ALL. HI COMES ON, CAN OPEN VENTS BUT NOT MUCH AIR FLOW. PLAN ON CONTACTING THE MANUFACTURER FOR A REPLACMENT MOTOR. THE FAN ITSELF LOOKS GREAT. VENTS FUNCTION AS EXPECTED ON HI ONLY. AS I SAID LOW DOES NOT WORK. EASY TO INSTALL HOWEVER THE INSTRUCTIONS ARE NOT THAT GREAT. TOOK ABOUT 3 HOURS AND A FRIEND OF MINE DID ALL THE WORK BECAUSE I WAS SICK. THANKS KEVIN YOUR THE BEST!!!!!

    Purchased this fan in Oct, 2018 after having the hottest summer in San Diego that I can remember. The frame is very sturdy, and the fan works well. Only gave it 4 stars, because I have not had a chance to try it out in hot weather yet. Used the joist in method to install it, because I did not want to cut out a joist. Instead of connecting directly to a circuit, I installed an outlet in the attic and used an extension strip with a 15 amp breaker in case anything went wrong. I also added a remote control with a timer ($14) that plugged into the strip. Since I am not good at repairing dry wall and I was using a remote control, I installed the 2 switches (that came with the fan) in the ceiling next to the attic access door. I can turn them off and on with a foot long ruler. I used a calking gun loaded with window ceiler to ceil any gaps. Hopefully, this will help to reduce my air conditioning bill next summer. Take a look at the pics, as they are worth a 1,000 words. The installation went well even though my attic is a pain to work in.

    I purchased this and it took a little over 1 week to be delivered to my store. I did not want the hassle of mailing it back if it was sent to my home thru HD or an online retailer and had any damage. To save time getting it in I figured Id prepare the attic and ceiling for a faster installation. I called the manufacturer to make sure the opening was right for a joist in installation, the woman that answered the phone stated they could help. I asked 3 times to confirm the size of the opening and the orientation of the Louvers. She gave me the wrong answer. I had to modify my installation and the flat 2 X 6's laid on top of the box since the fan dimensions are the same size as the opening: This was something customer service and the installation instructions FAILED to mention. Once the fan was installed I wired it PER THE INSTRUCTIONS and the fan did not work! The instructions told you to wire it WRONG attaching a jumper wire to the ground terminal on the other switch. I called customer service on Friday afternoon, it is now Tuesday afternoon and they NEVER returned my call. Once I got it sorted out the fan ran but there was a KNOCKING. after doing some research I experimented with the belt adjustment, the instructions say leave 1/2" of play, I left about 3/4" and it was still too tight. Bottomline the fan works, I do not recommend it UNLESS you are familiar with construction and electrical work, or are willing to pay to have it professionally installed! I would buy from another manufacturer/distributor before giving this company my business again.

      I put this 24" whole house fan in last weekend and am happy with it so far. I picked it up at Home Depot to minimize any possible shipping damages. It came very well packaged and secured in a box so big I thought they had sent me the 30” fan. A few comments on my installation: 1. It was a little bigger project than I expected because of the low attic space in my home and having to work around the air conditioner's air handler in the attic, and it being 94 degrees and humid in July in Tampa, Florida. The maximum height from the floor/ceiling truss to the roof sheathing was 46”, so the fan blades ended up 37” from the roof, just over the 36” minimum space the instructions call for. There was just one place I could put it, at the end of the house above the laundry room near the gable vent opening, which turned out fine, because the fan does put out a lot of wind noise -- like sitting inside the kind of pressurized turbo-prop plane airlines use for small cities. Or about the same noise level as my washing machine on the spin cycle. It is a nice sound, but too loud to be near the living room or bedrooms. The fan itself is very quiet, but it moves a lot of wind, which is the noise you hear 2. My (engineered) trusses were on 24” centers, and I did the frame-in installation, as it is not supposed to be a good idea to cut a truss member (even though I saw that two trusses had been cut fifty years and twenty hurricanes ago to accommodate the air conditioner’s air handler in the attic). My only access to the attic was through an 18”x18” panel in the ceiling, so I cut the ceiling drywall opening for the fan to 29" wide (wide being the direction lengthwise of the shutter vanes), instead of the instruction’s 28", so I could pull the fan housing up through that opening (with the motor unbolted from the housing). The shutter's flange ended up covering the 29" wide opening. 3. I wired the motor up before I took it into the attic and bolted it back on the fan housing. I ended up using an appliance cord and plugging it into a duplex outlet in a metal outlet box that I had just put in by the fan, after finding that power from a Romex cable connection I found that was unenclosed, the Romex and wire nuts just buried in blown-in insulation, until I routed it into my new metal box for the new duplex outlet. I then used a wireless remote-control outlet unit (the unit plugs into the duplex outlet and then the fan plugs into the remote unit) to turn the fan on and off from anywhere in the house. I can only turn it on high speed, which is fine for me for now. It was just too hot to keep crawling around in the attic to fish wires down to a switch on a wall. 4. The instructions say to make a 26” x 26” frame for the fan -- but the width of the movable shutters is 27”, and so would not open if the frame width is only 26”. I made my frame 28” wide by 26” long, then added a second frame of horizonal 2”x4”’s on top of that first frame, at an inside measurement of 26” x 26” to put the wood fan housing on top of. The top frame pieces I added that went in the direction perpendicular to the floor/ceiling trusses were long enough to screw into three trusses, making the top frame very stable. And while I was up there, I had added a gable brace retrofit, this being hurricane season, the lower horizonal 2”x4” part running through the middle of my frame for the fan. I used my cordless drill and #9 by 3” wood deck screws with a T-25 star-head on all of this framing attachments. 5. After using some expanding foam insulation to seal the gaps between my frame and the attic space, I got a can of white spray paint and painted all of the wood that would be exposed when the shutter’s vanes opened when the fan ran, so that exposed wood is now white and nicely matches the white shutters and white ceiling paint. It looks better than looking at bare wood when the shutters are open; see the photo. 6. I used 3/4” pipe insulation on the bottom edges of the fan’s wood housing, and four 2” “L” brackets/braces to hold the fan’s wood housing in place on my frame, cutting out the pipe insulation at the “L” braces to secure the braces to the fan frame itself with 1.25” wood decking screws. This seems secure and there is no fan frame vibration at all. 7. The 1.5” screws that came with the fan for attaching the shutter were an inch too short to work, as my ceiling drywall was attached to horizonal 1”x 3” slats nailed into the ceiling trusses themselves. I used 2.5” white-headed star-drive wood screws to mount the shutter to the wood frame I built for the fan.

        The fan arrived before expected in a fairly solid box. The box had superficial damage but the fan was okay. The fan seems well constructed with angle iron that is gussetted on the ends. The instructions show two different methods to install the fan but only addresses the simplest of truss situations you may have so construction experience would be helpful. The fan is light enough without the motor installed to easily lift in place and the motor and belt are easily installed and adjusted. The wiring diagram is easy to follow if you have even the least bit of wiring knowledge. The louvers are made from aluminum and are light weight. It comes with two paddle switches to operate it which is why I am giving it four stars. One switch is the on off and the other is the high low and they are set side by side in a dual box taking up twice the space as a single paddle switch would. It runs strong and guiet on both speeds and moves alot of air. Time will tell if it is durable but so far I have seen nothing to shake my confidence in it. I am including a photo showing the fan in my new construction being ran for the first time a few days ago. I built the framed openning per the instructions, so the louvers will fit exactly in the space provided.

        Best investment!!!!
        I live in the central valley in california and my word this has to have been the best upgrade to my house. This whole house fan was a breeze to install and litterally saves us $100 a month on our power bill when we run it. I usually turn it on about 10/11 pm and let it run all night. Cools the house down fast. We have a 1300 sq ft home and this puppy works great. Moves a ton of air. I built the frame out of 2x10s so it is far enough away from the cieling that it doesnt make much noise. Aslo between each board and board contact i placed 2 in foam gasket tape. Highly recomend this fan to anyone wanting to save money!

          The instructions were easy to follow and once installed worked very well. I had a direct drive previously and this one is twice as good. I have used it for a month for pulling in cool air in the evening with great success.
