Product Overview

It works by pulling fresh air in from the outside and expelling the warm air up into the attic and pushing it out through your attic exhaust vents.

can a thermostat be used since a thermostat would just supply power to motor for on/ off when temp reaches the desired level for on
Asked by: GT
I have used a thermostat now for 2 yrs on mine. I ran it in-line between the on/off switch and high/low switch. Works great.

The motor is quieter than the air turbulence from the fan blades. They are not quiet

I used HP 260 tape, which survives the heat in the attic well. I replaced a failed 30 inch fan, which was not sealed well (there were gaps the way it was seated to the space between living room ceiling and attic floor). This turned out to be very important, because now the 24 inch fan is pulling more air than previously the 30 inch fan did. Also, using rubber gaskets and securing each seat on the wooden beams with Household Goop made a major difference in sound dampening – the new fan is much quieter than the old fan. Very important: replace those low quality sheet metal screws holding the inner frame off the fan motor and fan blades with bolts with locking nuts and put household Goop over all the bolts so that they cannot shake lose for decades to come. Then you have an excellent fan for a fraction of the cost of what quiet and powerful fans cost today.

It is well built, structurally solid, and moves a lot of air. The blades are balanced and it is reasonably quiet. It ships with the blade assembly attached close to the motor, so remember to move it out before operation. I made an insulating door so did not use the included louver door. It also comes with nice toggle switches for power and hi/low speed. For the money, this is an excellent solution.

Rated 3 out of 5 by from Fair for price Easy to install, shutter is flimsy and a little louder than I thought but all of those are not big issues... biggest issue is customer service and the lack of response! Switch was defective and they have yet to send a new one.

Rated 3 out of 5 by from Good value This fan works as described and was a good value for the cost. However the instructions could have been better and written more clearly.

Rated 5 out of 5 by from Great value for the money I'm glad I bought this fan, it was easy to install by following the instructions. It's not noisy at all, in fact it sounds just like a standard floor type fan. It definitely moves the air thru the house very well. Originally when I opened the box, it was missing the wall switches and Wall Plate that was supposed to be included, but just a quick call to Home Depot customer service corrected that. They immediately contacted the manufacturer which in turn Fedex'd me the missing parts. Overall my experience was great and I have already recommended this fan to my co-workers and My brother. We'll worth the $199.99 I paid. Not only cools down the house, but it also cools down the Attic quickly.

Rated 4 out of 5 by from Very happy I chose to install this Whole House Fan!!! I wasn't sure if I was going to be able to install this whole house fan, but I was rather pleased to find out that is wasn't that difficult and was SO worth my effort to install it. I now use this fan almost every day to bring in cool air in the late afternoon or to just feel the breeze through my home...this was a "breeze" for me to install. I expect MUCH cheaper electricity bills now. I have yet to use my AC and much prefer to nice air flow through my home. I was very hesitant on trying to install this, for my expertise is not there, but surely I found that it went very smoothly, right down to installing the 2 switches (ON/OFF and High/Low) turned out to be not a big deal. The only drawback I could possible say about this fan is that it is a bit noisy...well, it is a large fan moving a lot of air, I expected it. But again, I cannot be more happy with the outcome. Even when my wife decides that dinner needed a little extra cooking, either the smell of fish sauce or the smoke of a neglected dinner on the stove, this fan is perfect and does exactly what I expected. From the montly savings in electicity for AC and the awsome effect of having fresh air running through my home, I 100% would recommend this fan for any home. The extras I needed to purchase to complete the installation was: 1. 2 lenghts of 2x3x6' for the base of the fan 2. An electric 2 bay box to install the switch (I actually used a 3 bay and replaced a single switch box that ran my laundry room fan into the 3 bay box that looks great) 3. 25ft of romex to install the power and switch 4. A power tester for the wire (I was being extra careful) Even cutting the whole in the ceiling proved effortless as the instructions were very easy to understand. Very pleased customer.

Rated 4 out of 5 by from Good Choice I was shopping around for a good WHF and went through different reviews, I got this fan from Home Depot on line and got it installed couple of weeks back. I am happy with it. Pl read the reviews through different sources to reduce noise. I have added foam to reduce noise and a timer for ease of operation. Before purchase, please check whether your attic vent has adequate ventilation (calculators are available in the internet) to prevent returning the product which is not only inconvenience to the seller and manufacturer but also loss to them. Any inconvenience and loss incurred to them is also to us as price will be jacked up to compensate the loss. I very strongly believe that good amount of research is a must before any purchase..Less ventilation at attic would overload the fan motor. This WHF comes with wooden box, two speed switch and a on/off switch. I engaged an installer and paid $220.
