We can not thank you enough for our incredible new Centric Air Whole House Fan. It is amazing how quiet, yet effective it is. Friends of ours have a whole house fan that sounds like a Train running by the house. We can hardly hear our unit running. But the best part is it is unbelievable how cool our house is. Last night my kids actually used their blankets to cover up all night. Not something we normally see. I typically have 2 fans and a window A/C unit on in our master bedroom just so I can sleep. Not anymore. Now I just open the windows, let the Centric Air unit do its job and the natural air from outside cools the house down just as though we had A/C going all night. I can not wait to tell our friends about your product ...it is just what my family has been looking for to ease those hot, sticky days & nights.

I had old styles home house fans in the past and they were loud, dirty and energy gobblers. The Centic Air is the quietest and best engineered fan that I have owned. Five STARS*****

Our Centric Air fan does a really good job of cooling off our house. Where we live it usually cools off in the evening which is when the fan excels. It pulls in the cool evening air and pushes out the hot air. The installation was quick and the crew left everything spotless when they were done. It also does a good job of clearing the air if dinner gets burned!

Had the 4.0 installed last week. What amazing product. So happy we have made the decision to purchase and install in our home. The ease of cooling the second floor from no fan to the whole house fan is night and day! Great start to a cooler night. Thank you!!

If you have a larger house like us, this whole house fan is definitely for you. The fan actually provide greater efficiency than other whole house fans, allowing us to cool down different areas of the house at once. I also like the variable power settings on the remote, which really makes it easy to combat both sweltering days and mildly unpleasant days. 5-Stars

We had a Centric Air 4.0 installed last year. We have used it every month. In the winter on warm days to draw in warmer outside air and every night during the summer. The fan really work and you can barely hear it. We run them all night long. Not only are we really satisfied, we were really impressed with the installer. At his suggestion we added extra vents. With the fan running the attic cools down in the evening keeping the house cool during the day. One more thing. Our electric bills this summer are way down. I did a lot of comparison shopping on the internet and talked to friends with fans. This one is by far the best, even though a little more expensive. Great product!! Told friends and received $50 checks. What a deal..

I live in the Ceres, California where it reaches 100 degrees regularly. After using your WHF 4.0 in my home for (1) month. My energy usage went from 2409 kwh for this billing period in 2013. To 1450 kwh in 2014. That relates to nearly $140.00 saving where I live. I only ran my A/C once the entire month. There was a couple times in the month that my home became uncomfortable. But my iPhone said the temperature was coming down in an hour or two. So family suffered for a little here and there. But it’s funny to have to shut off the system at night because my family is freezing. Best purchase I have made in years for my home. Thanks for the great product.

Purchased this quiet whole house fan for a client, installed it last summer. All I can say is WOW… This fan is so quiet I had to get back up on the ladder and stick my head up there to make sure it was actually running. Compared to the old school belt driven fan that was ugly, noisy, dirtying and drafty, there is no comparison. The build quality of this unit was impressive, now I’m going to be getting one for my own home! Installation is very straightforward, took longer to muscle the old fan out of the attic then it did to install this. Even though I am a contractor, I would say a weekend warrior, or average DIY should have no trouble installing. Instructions are clear and easy to follow, and presale support was excellent, I had no need to contact them after the sale as it was so easy to install. I would imagine their support to be excellent given they have quick and friendly communication. If you are on the fence and shopping your local home improvement stores, do yourself a favor and stop looking. Yes, the unit is pricey compared to the junk local stores sell, but the quality, energy efficiency and lack of noise are WELL worth the cost!

I have had Whole House Fans in all my past homes but they were both noisy and energy gobblers. The Centic Air is the quietest and most energy efficient whole house fan that I have had. Love the 2-Speed remote and the R-50 damper since I live in Colorado. 5-Stars thumbs up!!
