Tamarack Technologies HV1600R38 Whole House Fan Insulated Doors

On high it'll spin my 1500 cfm roof mounted exhaust fan blades directly above it, even when thevroof fan is not running. I turned a garage into a bathroom basically by putting a hottub in it. Sealed the ceiling and walls off with closed cell foam except for baffles going to the soffits. This allows me to adequately air everything out properly to deal with moisture, and when not in use, insulated and airtight. This is either on or off. It can either be controlled by remote or a switch, but not both. My roof mounted exhaust fan has it's own humidistat and thermostat so it operates independently. So far so good.

We have an older 2300ft home. This units hums. It’s a little loud on the high speed but that’s great white noise. Make sure to change the batteries in the remote. I learned that lesson dealing with one of their top engineers who doubled as tech support.

This fan does nothing. Makes zero difference when it is on! Our house is 1910 sq ft, this fan is for 2000 and above. It should have NO problem moving air in our house. It literally couldn’t even move a speck of dust, not even on “high.” The remotes are a joke, as well. Should you decide on this (BTW: don’t!!!) have your electrician install an on/off switch. Don’t count on the remotes. It takes 30 min sometimes just to get it to turn on... and then it’s even more frustrating because once you do get it on, it can’t even cool you off. Buyer beware. Believe the reviews.

Easy to install - installed in an elevated (12") above the insularion in the attic. Took an afernoon to build out the box, install the fan and air seal the seams. This is my second Tamarack fan. In 2004 my brother and I installed the Ghost in a larger home I have in Oregon. Love their products.

I really wanted to like this fan, but it just doesn't have any power. While there are many positives, the insulated doors, not having to cut through a joist in my ceiling, the ease of installation... When it comes down to it, this thing just does not pull in enough air from the outside to make a difference. You can't feel any breeze inside from the unit when it is running, even on high speed. After running for 2 hours in the early evening after the sun is no longer hitting the house, if we are lucky the temperature inside will drop by 1 or 2 degrees, which is not very much considering the air outside is about 10 degrees or more colder than the air inside. We use the fan in new England in a small 1 story 1000 sqft cottage on a lake and it doesn't seem to do the job.

Works well and is quiet, relatively. The insulation works well here in the Colorado winters.

The unit is noisy and for the cost I would think it would not be.Would not recommend it if you are looking for little to no impact on on back ground noise.

I have installed several whole house fans. I first used a gable mount fan and built a box around it, then added on/off switch, timer, and motor controller to vary speed. That was about 25 years ago, and worked very well, even though the roof was about 2' above the fan. After kids and a move to a larger home, I installed a 30" Master Flow. We loved it! The only problems were doors had to be open, and sometimes would SLAM shut unexpectedly, causing brief heart racing each time. After several years, I moved that fan to a better location, from main hallway to a mud room. The problems with all three installations were that the large openings to the attic allowed cold/hot air to enter the house unless I closed off the opening with significant effort and insulation. The need to block off the opening made it important to disable the power so the fan could not come on while blocked. So season changes were somewhat of a pain. I certainly could have designed and built some type of doors, but time and procrastination prevailed. I keep up on things and saw the Tamarack a few years ago, but balked at the price. It is amazing how our perceptions and priorities change over time. My wife has MS, and heat/humidity is her enemy. I have arthritis and an old golf injury. I also have replaced kid raising with young adult raising. I now find practicality and wisdom dominate my decision making processes. A new look at the Tamarack and a week of higher than normal heat made this an easy call. Luckily, I did not view Amazon reviews first, which is pretty rare for me. We have central ac in our attic, and our perimeter walls are blown in foam. Our house heats slowly, but also cools slowly if it gets hot. I opted for the R50 1600 model, at $937/free shipping from Tamarack. I worked hard all day on replacing my fascia over the garage door in 90 degrees. The fan arrived about 5pm. I decided it would be functional by 10pm. And it was. The install, even with the inevitable unplanned things, was easier than the first 3, mostly due to ease of wiring. This unit just plugs in and is controlled with a radio remote. So building the box was most of the work. I had a spot from the prior installation, so I just needed to make it smaller and remove the drywall. My pasload framing nailer quit on me, so I used screws. The fan moves plenty of air, although less than the 30" unit. It is quieter, even on high. I am still "planning" on addressing the need for bedroom doors to be open. The remote did not work from our bed, about 45 feet away. It did work at the foot of the bed. I plan on adding 2 single pole swithes for on/off and speed, in case the remote fails. I cannot say what the reliability will be. I feel that if this unit works for 3 years with no problems, that amounts to about $300/yr for the function and convenience. I find this minimally acceptable. Anything over that is gravy. It has a 3 yr. warranty. We shall see. I am guessing the insulated doors would be the weak spot. As a lifelong electronics tech, I expect the mechanical components will likely fail first. The fans should go forever, in my opinion. Think computer cooling fans, without the heat problem. If you keep them clean, there should be no problem. Again, we shall see. Finally, I concede my 5 star rating may be due in part to my extensive electrical/mechanical experience, 56 years of life experience, and a generally positive attitude. One thing you can count on: I have absolutely no bias toward the product. I simply want my problem solved efficiently and in a cost effective way. Respectfully submitted for your consideration.
