Customer Questions & Answers

noise factor

The fan I am replacing is very loud when running. How loud is this fan?
Asked by: tony
Quite loud. Cannot use high speed at night, and even low speed is loud enough to be annoying at night - mine is mounted in the proximity of the bedrooms (second floor).

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.

My original has a 3 blade fan Will it make a difference to replace it with the 4 blade fan?

I originally was going to only replace the motor, but find the whole unit is not much more than a replacement motor.
Asked by: susie
As long ad your dimensions are the same the fan will work 4th blade only increases airflow.

I have an Emerson Direct Drive 30" that is 27 years old and has variable speed dial, works fine and is quiet. This whole house fan is garbage. It sounds like an airport when you put it on low speed. The shutter is almost made out of paper. Had to put nails behind shutter door opening so it does not open to all the way. If it opens all the way it does not shut by itself. Didn't come with mounting brackets. Had to build a frame. What garbage.

Thought I would just use the motor and fan blades, popping it into the existing frame, easy peasy. Wrong. Dimensions were just enough off to make it easier to replace the whole thing. Just as well: the framework is vastly superior to the old one.

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.

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
