Suncourt Flush Fit Floor/Wall Register Booster Fan — Ultra-Quiet, 5-Speed Vent Fan with Smart Technology and 6-Foot Power Cord, HC500-B (Brown)

The unit out of the box is actually great if you don't mind the bearing noises/minor rattle. The fans are loud so if you don't mind that they will be fine. While I don't mind a little white noise in the background, when it comes to my computer room with three workstations running it can get warm and I have all of my systems setup to run silently so I can work and have meetings. This unit has loud fans which to be fair push a lot of air and work great. Keeps the room significantly cooler when running. On that note I modified mine and changed out the fans with the be quiet 92mm fans that push about 33cfm. This is maybe half of what the originals put out but the difference in sound is unquestionable. Other than the sound of the movement of air they are completely silent and I just let them run at full speed. great "as is" if you need a room to be cooler or warmer but with modification if you want to cut down the noise it becomes amazing.

These were absolutely life changing. If your HVAC cannot effectively reach upstairs, buy these now. We had 20 days over 90 degrees this month, and have slept so comfortably. Last Summer it was 71 degrees on the main floor and 85 degrees upstairs. I have recommended these to my neighbors, and those who actually listened have all reported back the same life-changing stories... along with being upset they've dealt with sweltering heat all these years when there was such a simple, inexpensive and effective solution. Some reviews mention the noise, but I say "whatever." Low speed is pretty quiet and works plenty well, and you'll get used to it in a night if it even bothers you at all. I could see someone complaining about the noise at higher speeds, but we've never needed them, and frankly you'd get used to it anyway--it's basically just white noise, and some people pay stupid money for white noise machines. Some reviews also complain about the power cord... Are you kidding me? For the benefit of a cool, comfortable night's rest, I could not care less about the cord. By way of scenario... We're in a three-story townhouse community built in the 70's with zero insulation on the front and back walls and four inches of attic insulation. Everyone in the neighborhood melts upstairs in the Summer or opts to camp in their living rooms or basements. The usual advice is to spend a few grand to better insulate the attic and open up the walls to add insulation. We got one of these after a neighbor recommended, were amazed at the results, and the next day got three more for the rest of the upstairs registers. What a small price to pay for virtually unbelievable results vs. adding attic insulation and tearing open walls and ceilings to install a split HVAC system. Side note, while these worked insanely well and I could have stopped, I kept going. I added R-38 unfaced insulation to the attic along with Reflectix radiant barrier to the roof deck, which both definitely helped even more--the HVAC is operating more efficiently with slightly lower power bills than last Summer. The insulation was obvious, but it was the radiant barrier that surprised me. I very highly recommend the radiant barrier, which truly lives up to the marketing and reduces the actual temperature inside your attic. It was in the low 70's when I installed the radiant barrier, and my attic was like a sauna. It was in the high 80's when I then installed the attic insulation (poor planning I know), but here's the thing... the attic was actually cooler than when I installed the radiant barrier and the outside temperature had been in the 70's. I could not believe the effect of the radiant barrier, and recommend to everyone (depending on your latitude).

I purchased this fan to augment the flow from an under performing basement vent. This made a huge difference. My basement is finished, but gets such poor airflow that it was about 15 degrees cooler than the rest of the house. With this fan operating it is about the same temperature as the main floor. I purchased one of these units as a trial and just ordered a second for another basement vent. The ability to set the fan to come on when the heating or cooling operates is nice, that way it augments the airflow. It does take quite a bit of tweaking to set properly. I have also turned the fan on; it pulls air from the rest of the house and makes a big difference as well. The fan uses a thermocouple in the airflow to sense when the heat or AC is operating. I have a thermostat that runs the furnace fan to circulate air without operating the heat or AC. I have doubts about this fan being able to sense this airflow. The fan is fairly noisy. If you take a pair of dikes and cut the fan covers off of the rear of the unit, the airflow improves by about 50% and the noise is reduced about 75%. My fan is located right above the couch in the TV area of my basement. With those covers removed the fan noise is easily ignored. I do not notice it at all. The plastic shell of this unit has small circular pieces on the short sides. They line up perfectly for screws to mount the unit in a ceiling vent. I did so and it works just fine. The LED indicators on the unit are very bright. I agree with one of the other reviews: a bit of duct or electrical tape can cover those up nicely. The power supply that comes with the unit is junk it seems to weight about half a pound and gets fairly hot. I spent $7 on a level 5 energy efficiency rated switching power supply from Digikey - part number T983-P5P. The power supply needs to be 12V with at least 500mA output. The plug is standard DC power plug: center positive, 5.5 mm outer diameter, 2.1 mm inner diameter. * Amazon and Digikey carry DC extension cords that fit the above connector. I bought part number CP-2213 from Digikey. Has the same right angle connection of the original power supply.

It works well. My son’s room is always cold. The register is under the bed and has a deflector. This makes his room at least a whole degree warmer. The noise level isn’t bad. He sleeps with a fan and this is no noisier than that. And it only runs while the furnace is running. We will be using it in the summer with the A/C as well.

I have mixed feelings about this product. On the positive side: It works great, our master bedroom it upstairs and the farthest registers from our central air system so the airflow was terrible. After putting in the fan, it made a huge difference and is great. The air flow of the fan is great and it is super simple to use. Has a thermostat that seems to do the trick nicely when you dial it in where you like it. On the negative side: The fan is relatively loud. No so loud that it is unbearable, but it is noticeable. I would compare it to the a slightly louder isolating fan. Because it is in our master bedroom, it is right next to our bed and you can definitely hear when it turns on. I am right on the fence if I would consider it "too loud".

Got this to try and get more heat into a downstairs bedroom that was not getting much heat/cooling from my furnace (too many turns in the pipe). It works wonderfully. Set up was simple using auto mode. The room gets much warmer now. Turns out to be a great purchase.

Aún no le realizan la devolucion del producto por qué supuestamente está en tránsito pero ya pasó más de un mes

Used this for a second story bedroom that just wasnt getting cool with our central a/c on. This booster fan wad amazing. Easy to plug and use. And cooled the room right down!! Highly recommend if you need a bit extra air flow, heat flow or cool flow in a room.
