  • Works Great, Easy Installation
Color: White 6" x 12" Size: 6" x 12"
I was a bit skeptical of this item at first, had a different product years ago that didn't seem to help. But the second story in our home tends to run 3-5 degrees warmer in the summer than the main floor where the thermostat is located and took the chance that this may help. Installation was quite easy, just make sure you get the right size, loved that they had a variety of size choices unlike many other competitors. I admit, it took me a few minutes to understand how to lock in the settings correctly, but got them eventually. The highest fan speed is a bit noisy, but we are a fan family and it's more just like background white noise. And we'll take the noise because the velocity with which it pulls the air is quite strong, you can feel it from several feet away! We are very happy with the unit, when the AC is running, it cools the room to the exact same temperature as the thermostat is set, even a degree lower sometimes! That being said, you have to understand how it works. You program the cooling temperature lower than the thermostat setting by a few degrees, but not colder than the temperature of the air when the AC is blowing. The fan should be off until the AC starts blowing, and once it senses colder air, the fan turns on. This means that when the AC is actively blowing, it makes a significant difference in the room temperature. However, if there are longer periods when the AC is not blowing, the room temperature will creep back up because the unit is off (as it should be since it would then be pulling in hotter air just sitting in the vents). Just a word of caution so you have realistic expectations. My only minor complaint is that it does seem to take a couple minutes to turn on after the AC starts blowing, and stays on for a couple minutes after the AC clicks off. But it's a minor issue and does not seem to detract from overall performance. ... show more

  • They Work!!
Color: Black Size: 4" x 10"
Our master bedroom is over our garage. Even though the garage is insulated, for the past 5 winters of living in this home, The bedroom has easily been 5° colder than the rest of the house. We have a nest thermostat and we have a second thermostat sensor in the bedroom. I would say that we got and installed both of these fans by mid-month Jan and you can see how much the energy use has gone down overall since. We did have a few very cold days this past week so take that into account but the temperature has stayed consistently within a degree or the same as the rest of the house since we started using the fan vents. We tried another brand first that had more technical bells and whistles but I find this one to be quieter and easier to set. I have the fan set 5, and it remains fairly quiet. I set the cold to off and I set the heat to kick on when it tracks below 70 in the vent. We are an all-electric home on a heat pump so I suspect if you had gas heat you would set it on a higher setting but with a heat pump, it's only using the recirculated air anyway so I set it lower than recommended. For our electric bill, the goal is to try to avoid the auxiliary heat kicking on. I am happy we have been able to do that barely successfully. It used to be that every night in the middle of the night when it was at its coldest we would use a ton of power. Just trying to maintain the temperature. It's a fairly large room about 10x 20 and we have two vents that are right near the windows and the edge of the garage, which would probably be the coldest part of the house. These are what we put the fan vents in. The other two vents are tucked away in the ensuite bathroom, and the walkin closet. Even though they keep those places warm, they don't put a lot of heat out into the room. These have been a game changer for us and I haven't done comparisons with our heating bill yet, but I expect it will help based on what our sense monitor is saying. I am just so happy to be able to shut the door up here and not freeze and not worry about using a space heater and to have this room stay the same temperature as the whole house. Definitely worth it! ... show more

  • Great Device
Color: Bronze 4" x 12" Size: 4" x 12"
No more expensive portable room air conditioners that last less than 5 years!! These work to cool living areas: kitchen in the mornings, bedroom at night. Can't say they are 'quiet' when fan is set to high (8-10), but it's not invasive, more like airplane engine noise at cruise altitude (white noise actually puts most people to sleep, the reason so many people take a flying nap). Settings are simple to make and so far, no problem with digital panel working as expected. Important Note: these plug into electrical outlet, so carefully consider whether they can plug in near your target register vents. Elec cord is reasonably long. I've only used these for one month (summer) with central ac cooling, so can't speak to longevity, but with my bdrm door closed for an hour before bedtime, they bring temperature down abt 10 degrees (with ac running, then I turn central hvac off at bedtime, bdrm stays cool all night). Colder rooms help with getting to sleep. One more thing. These vent units measure the air temp blowing from the vent, not the room temperature. You select the vent temp -- for summer mine is set to come on when vented air is below 70; next winter over 80. Note: an issue arises when trying to set both at same time (not a flaw, issue is covered in instructions), simple to set it once per season. ... show more

  • It Does The Job!
Color: White Size: 4" x 10"
The helped greatly in solving my cooling problem. A little tricky to set up, but once you get it where it works for you, you can forget about it. It is fairly quiet except when it on the highest speed (10),then it is noticeable.
