Customer Questions & Answers

Does the switch on this need a single or double gang box?

I'm replacing an older unit that stopped working and it only uses a single gang rotary switch for it On/Off/Speed control.
Asked by: Scott
double gang box with 1 on/ff, 1 high/low switch by default. I believe you can buy 1 switch with High/Low/Off and installed on single box, please download the manual and check the wiring diagram to confirm.

Customer Reviews

30 in. Direct Drive Whole House Fan with Shutter is rated 3.9 out of 5 by 22.
Rated 1 out of 5 by from Absolute Junk I feel so strongly about this product that I am posting an update to my original review dated July 2014. The fan lasted just over one summer, quitting mid-August 2015. My original review is a bit lengthy but the bottom line was that I was not satisfied with the fan as a whole. One of the positive aspects, one might think, is that the fan comes with a 10 year warranty so other than the fan not working during the season it is most needed and all the effort to remove the faulty motor and ship back to the factory at our cost, at least I would receive a new motor. I decided to stay out of the 140 degree plus attic and instead, removed the incredibly flimsy louvers and work through the ceiling opening. The removal of the motor was awkward but accomplished without too much hassle. Afraid of damaging the flimsy louvers, I covered the opening with the much heavier louvers from my previous fan. Total time to ship back to the factory and receive a replacement motor was just over a month. The best part of that transaction was a note included with the “new” motor informing me that since I had the audacity (my word) to actually invoke the warranty, the “new” motor only had a 1 year warranty – so, poof, just like that the 10 year warranty was reduced to approximately 2 years and some change. I was not able to install the new motor until the beginning of May, 2016. Installation went fine without any major issues. However, trying to install the unbelievably paper thin louvers resulted in a bent center section, 3 bent louvers, and probably a few months off my life. Just to add salt to the wound, this motor doesn’t open these louvers all the way. Conclusion: This was and is a horrible piece of junk – cheaply made all around and no way worth the price being asked. We’ll be lucky if this install lasts over a year. Forewarned is forearmed… Do yourself a huge favor and look at some other manufacturer.

I had 2 attic fans before, it works, but only reduced a little on the temperature, didn't save in electric bill. Installed this whole house fan this week and removed the 2 attic fans. This one drops the temperature very quick when outside is not hot. I have about 2700 SF one story. less than a hour, it cools down the house and attic. It is a little noise when on high, but not too bad

Not an easy install due to different sizes for the fan box and shutters, but the fan works as advertised and I am really enjoying it. I added a 12 hours timer to round out the installation of this product.

Rated 2 out of 5 by from disappointed - low quality but functional I Ordered the cool attic 30" direct drive fan on-line from HD for my 3400 sq ft split level and had it delivered to my local store. The fan arrived 2 days early, however the box was damaged and a repair was attempted with clear packing tape. I Opened the package at home and found that the two electrical switches that come with the fan were missing their screws to mount to the outlet box and both switches were bouncing around inside the box and were not packed as you would expect, The louvers had 3 globs of white paint approx 1/2" each in diameter that someone in "quality control" had apparently applied to cover 3 scratches that had occurred at the factory. As reported by others, all the screws were loose and had to be tightened. The whole fan was put together rather sloppily at the factory but with some modification I got it to where it would work. I contacted HD about the louvers who in turn contacted Cool attic who in turn sent me a new louver assembly. This package was also damaged and three of the individual louvers were bent. Instead of calling to complain, I took 3 good louvers off the original louvers and replaced the three that were bent and made one that looked and functioned ok. The louvers are made from very thin metal and bent quite easily, On a positive note the fan moves a lot of air and does what it is supposed to do. It is loud, but not as loud as I feared based on other reviews. Overall the fan is pretty cheaply made and the quality isn't there, but it does move a lot of cool outside air into the home at an affordable price.

Rated 4 out of 5 by from Worthwhile Investment But Be Prepared For the Installation I bought this solely to reduce my overall A/C expense. The box it comes in a very large to accommodate the protective packing and I was concerned if I was going to be able to get it into my car but it did fit. After unpacking the fan, there was a small den in the area surrounding the fan blade but that did not impact the operation. Now, finding someone to install it was a different matter. Most bids were for $600 on up. My neighbor, who happens to be an electrician, offered to do it for $20 per hour and it too him and his father 9 hours to install from start to finish. Some of that time included having to stop to go to HD twice for needed parts, such as wood to create the frame and then the electrical wire. The moment we turned it on for the first time, everything ran perfectly. He did mention that the motor housing that drives the fan was built in a way that made it difficult to run the wires into it. Also, investing in some weather stripping to lay down on the area where the fan will rest and be mounted to. This not only helps make a seal around the fan's frame but reduces vibration and noise. The fan is surprisingly quiet on HIGH mode. I don't see a big difference between the LOW and HIGH setting so I am keeping it on high. It reduce the temperature of the 2nd floor of my house from 80 to 72 in a couple of hours, versus running the A/C. Make sure you have plenty of vents in your attic to exhaust the air being pulled into it or the motor will shut down as a safety feature. That isn't the case with me since we have 8 vents but I thought it was worth mentioning. So far, I am very happy with the purchase.

Rated 2 out of 5 by from Simple whole house fan i recently replaced my 25 yr. old whole house fan when the direct drive motor stopped. This Home Depot model is extremly loud and is not nearly as efficientl as my old model. Old model on high speed would actually pull window drapes out into the room. Not even close with this loud Home Depot model

Rated 5 out of 5 by from AWESOME !!! I grew up with whole house fans in CA, and put some in my own homes as well....after moving to TX, I could not wait to put in another. The fan arrived ahead of schedule at the store, and everything was intact...no damage. The directions were easy to follow, and after installing the enclosed switch in the hallway, ta-daaaaaa...new whole house fan that works great !! Last nights, it was a cool, crisp 65 in the house after leaving it on overnight. Does not seem as loud as previously owned ones...I will look into adding stops for the louvers (see previous review), since one side doesn't want to close all the time.

Rated 3 out of 5 by from Disappointed I purchased this fan to replace a 30” whole house fan that I originally installed almost 25 years ago (a wonderful addition and unbeatable for efficient home cooling). The bearings were beginning to wear out and the fan was sufficiently old that no repair parts were available. Because I already had a ceiling opening that measured 301/2” x 301/2”, the challenge became trying to find another 30” fan that would not require extensive ceiling repair. This particular model came as close as I could find – its louvers (shutters) are a bit narrower and a bit longer. My idea was to center this new fan over the existing hole and make use of the existing louvers thus eliminating any ceiling sheetrock repair. The original fan was specifically designed for roof trusses built on 24” centers and had heavy duty legs that mounted to the trusses / joists at four points – side to side and front to back (the center joist was not removed). The new fan is essentially a wooden box which you install on a boxed in area you construct across your attic joists. You have the option of cutting the center joist thus allowing the fan housing to be hoisted diagonally through the ceiling opening or leaving the center joist intact but figuring some other way to hoist the housing into the attic. The new fan motor is mounted on two sheet metal strips that span the width of the box. The fan motor is held down on the sheet metal by four nuts. Once the old fan was removed, the new fan installation was straight forward but not as elegant as the old fan. I did not remove the center joist. I did think to check the nuts holding the fan to the sheet metal and found three of the nuts (not lock nuts by the way) loose. For safety reasons, I applied some “Lock Tight” to all the nuts and retightened. The fan motor has four wires – ground, neutral, red (for low speed), and black (for high speed). There are two paddle type switches supplied – one for on / off and the other for speed selection therefore you need a double gang electrical box as well as the proper wiring run to supply the two individual speeds. Since the existing wiring from my old fan was the typical wiring for a single pole switch, I decided to try each speed individually before changing out the switch box to a double gang and running additional wire. So happy that I did – even with no louvers (shutters) attached to the ceiling, the low speed was so anemic, it would never be used by us under any circumstances. Wiring for just the high speed allowed me to stick with my original wiring and box. Having completed the wiring, I closed everything up in the attic. I then installed the original louvers in the ceiling opening and turned on the fan (defaulted to the high speed). Other reviewers have commented on the flimsy louvers supplied with this fan. Immediately upon turning on the new fan, I could understand why the supplied louvers are so light weight – the fan moves only enough air to open very light weight louvers. The original louvers from my old fan are not all that beefy but even so, the new fan can only open them about half way. The amount of air moved, compared to the old unit, is disappointing – it takes far longer to cool the house down. For now, we will do with what we’ve got. Once we get out of summer, I will install the louvers supplied with the fan and see if it makes an appreciable difference but I don’t think it will. Bottom line: Pros – not too heavy, fairly energy efficient, relatively easy to install, soft start, thermal protection, quieter than my previous fan; Cons – low speed seems way under powered, high speed should move more air, compared to the previous fan, not great.
