QA-Deluxe 5500 Energy Efficient Whole House Fan – Plug & Play, 2-Speed Temperature/Timer Remote Control, Removable Grille – 10-Warranty – Up to 3400 sq ft (2-Story) & 2400 sq ft (1-Story)

I have been wanting to buy this unit for years, but was wondering if it was worth the price. Finally purchased it a few months ago and writing the review now after a few months of use.Installation was fairly simple and can be handled by somebody with an average amount of handyman skills. I think the manual could’ve been a little clearer in some of the steps. For example, for some reason the giant 18 inch wide flexible duct had an arrow on it indicating the airflow direction. I don’t know why it has this but I’m sure there’s a reason. I, of course, did not see this and installed it the wrong way. I feel the manual should’ve called us out. Not a big deal, it was easy to remove and reverse.I used a cheap truck ratcheting tiedown strap as an additional support on the flexible duct to make sure I got the L shape that most reviews talked about to reduce the noise from the motor getting back into the house.I really like the wall mounted control. It has a high/low fan option and a number of different time options. Very simple for anyone to use.I am an engineer, so installed a bunch of temperature senses around my house when I turned the unit. It was 82° in the house and 72° outside. I live in the north east and it was 7 PM at night . On the high fan option, it dropped the 6° in the first hour and starts to feel more comfortable within the first 15 minutes. This was repeated on a few different nights over the course of a few weeks. One night I let it run all night long and woke up to a wonderfully cool house. I could feel the cool air entering from the windows. When I turn the unit off, that cool breeze stopped.It is not perfectly quiet, but I feel it’s a lot less noisy than the ceiling mounted fan units. Certainly not loud enough to cause any irritation from me or my family.I am very pleased with the unit, very well made, unit arrived in good working order, installation was fairly straightforward, and feel it is worth the cost. Overall, very happy with this unit and the purchase!

Great product, easy to install if you are handy. Great power to pull in that outside air. Noise level is medium. The 2 speed wireless remote is wonderful. I would recommend this product.

It works as it described. We are happy to install it and there's big difference on our 2nd floor once the fan turned on. It is somewhat loud at high speed but pretty quiet at low speed. I wish we could have installed it sooner.However, there are minor things to improve. The instructions came in the package as well as the video on their website are not clear on how ducting is connected to the damper box and fan. It is as simple as drilling the bolts in. However, with concern about damaging the damper box and the fan, I looked up available instructions but they are not very helpful. In addition, instructions say no obstruction within 4 feet of the fan. It's not clear what obstruction indicates. I was concerned if wood beams would be obstruction but it turns out not.I got answers from the company staff for the questions I had, which is pretty helpful. However, I wish they be provided more specifically. It definitely helps your installation typically about an attic environment which is a hot and narrow with clear instructions, let alone you have to crawl up and down from your living area to the attic.

Love our whole house fan. We got a slightly more powerful one that what was recommended for our home size. The 5500 is what we got for our 1650 square foot home. Setup and install was relatively straight forward and on low mode you can hardly hear it and in high speed it’s about the same loudness as the AC running. We use it with the kitchen window open in the corner of the house and the breeze fully circulates through the house for rapid cooling. We went almost 3 weeks without having to use our AC but as the heat wave starts now I’m so glad wr have this to start saving on our cooling costs.The only issue I ran into was the remote was faulty and not working properly when trying to activate it. I called the company and the owner of Centric Air called me and sent the info to the other company who makes their remote. The owner of that company also called me to assess the issue and immediately sent me the replacement remote and controller. I did have to climb back into the attic and rewire the controller to the fan as the remote is preprogrammed and paired with the controller. It works perfectly now and all our friends want one now.

This is one great product went in real quick and works excellent boy more excited about using this good job guys John with JND electric
