This register booster is a solid five star from me! I live in a 115 year old house and for over 20 years, one of the bedrooms has always been colder than the rest of the house. I learned it is because that room shares a duct going to the bathroom which can be solved but with the ducts wrapped in what I suspect is asbestos, re-ducting is cost prohibitive. Last month after walking into the room, I realized it was nearly 15 degrees cooler than the rest of the house so I put my mind to task to find a solution that is not duct-invasive...After some research, I came across the AC Infinity brand of boosters and decided to take a chance. WOW am I amazed as to how effective the product really is! My house only has central heat but this product works for both ducted heat as well as AC. The programming logic is simple but can be perplexing at first because it is backwards from a normal thermostat. For the booster to function, you program it to come ON when its sensor detects the desired air. In my case, I want heat to be boosted to the room so the logic is set so that the fan comes on when it senses air that is greater than 75F. The ambient room temperature is never that high in the winter, therefore the fans will only come on when the furnace blows the hot air through the ducts. Even with the slightest whiff of hot air that BARELY would come out of the register, the booster sensor detects it at 75F then initiates the fans (I set mine on medium)...Sure enough, less than 30s after the furnace comes on, the booster kicks in and pulls the air up and into the room. The shared bathroom vent does not suffer from the booster fan pulling air which was a concern of mine. Both the bathroom and this bedroom are now less than 1d off from the rest of the house. FINALLY I feel bad that I just now installed this, years after the kids moved out of the house. This room used to be their bedroom since they were little and they always woke up to a frigid bedroom which sucks. I honestly never thought about a booster fan that had logic built in to it the way this one does. It is also whisper quiet, pulling in the desired air without any noises. The power cord is the only bummer but they supply a very long cord to the power plug that goes in to the wall. It is powered by 12vdc so I am sure there are other ways to sneak power to the booster for those that want a seamless install, however for me...I just wanted it to be effective and it is. The fit and finish is high quality as well. I went for the bronze look and it looks sleek, even in this old house. The LED lights on the front are not bright enough to keep a person awake, although you can even program the front lights to go off for a light-free experience. The booster can also be programmed for AC. Simply set the booster thermostat to trigger the fans at a low temperature like 60F. This may not make sense when reading but believe me, when your central AC kicks in, the air coming out of the vents is WAAAY colder than 60F so you basically want to give the booster a "hint" that the desired air is in the vent and that it needs to turn on to pull it out. For example, in my case when the heat kicks on, the booster sees rise in vent air temps and when that air gets to 75F, the fans kick in and pull the hot air out. Eventually, that hot air reaches a balmy 96F at full tilt. I used a laser temp tool to measure the heat at other vents and its the same! That might seem abnormal but it isn't. For AC, the air can be as cold as 40F coming out of the vents so .... think about how you want to trigger your booster fan... Long story long....This product is effective...It's well made....it's inexpensive...It looks good...and most importantly, it allows the room to be comfortable just like the rest of the house! So don't wait...Hit that "Add to cart" button and get it!

I purchased this booster fan to bring additional heat to a bedroom in the northwest corner of my house. The bedroom is quite cool in the evening. The register fan worked very well but keep reading to get the full story. Installation of the fan was extremely simple. I removed the old register cover and this unit fit exactly into the space, with the circulation fans, sticking deeper into the wall cavity. My electrical outlet unfortunately was on the left side of the unit, about 3 inches away, so I had to wrap it around the register with the additional cord management piece they provide. The register is held in place with two screws. One screw went in perfectly using the old screw hole, the other screw hole didn’t match up so I had to drill it out, which only took a minute. Once the unit was mounted on the wall, I plugged it in. There are 3 settings you need to adjust based on your personal preference and the room temperature: Fan speed, activation temperature for heating and activation temperature for cooling. Remember you are not setting the desired temperature of the room. Since this room is usually a bit chilly, I did not want the fan to start blowing cold air thinking it was in air conditioning mode. So, I lowered the temperature of the air conditioning activation to 60 degrees. I wanted the fan to start as soon as hot air is blowing from the furnace, so I lowered the heating activation to 76 degrees. I turned up the furnace and watch the temperature climb on the unit and once it got to 76 degrees the fan start working and it was pulling more heat into the room. I might have to adjust the hot and cold activation temperatures in the summer when the room is a bit warm, so it is not blowing warm air if the room is 76 degrees or above and instead just comes on when the air conditioning has activated. I did increase the fan to speed 7 over the next couple of nights, so it was providing quite a bit of heat, but not so noisy as to be a bother when you are sleeping. Overall, it has helped tremendously with getting a more comfortable temperature for the room. I feel it was a good investment. The good: Unit works just as advertised, very flexible for setting activation temperatures and fan speeds. Easy to install. Seems like it will be very durable. The bad: It doesn’t turn off when it is activated until the temperature sensor is above or below what you have specified, no matter what the temperature of the room becomes. And the big thing is of course, it does not help at all, when the furnace/air conditioner are not running. So there are times when the room is still a bit cool, because the rest of the house is at the desired temperature for the thermostat and the furnace is not running. What I wish: I wish they would partner with EcoBee thermostats and could activate the register fans when the furnace fan is running. Also, they could be a remote temperature sensor for the thermostat.

I give the air flow 5 stars, but now that I have multiples of these, I'm frustrated enough to deduct a star from the review of this unit. I got this T6 for the hottest room in the house. It worked so well to bring cool air into the room, and this part of the house that lacked negative pressure, that I got a T4 for my office next door. It does exactly what I needed as these rooms are furthest from the central unit. Now, with both of these AC Infinity units on this side of the house, the whole A/C system runs more efficiently, because the thermostat is also on this side of the house and cold air is actually flowing on this side of the house. We were really struggling with what we were going to do in our hot climate to deal with this issue. So, this was immensely helpful. When it's at its highest fan speed, there is fan noise, but turning the fan down to the point there is little fan noise still produces great results for extracting cold air from the ducts when I am in the room, and I need it quieter. I have a bone to pick with AC Infinity. The T4 unit I got after this T6 unit came with a dedicated remote control! While the unit has a digital display with buttons, I'm too short to reach them without a step ladder. The Bluetooth app doesn't work very well, tends not to stay connected, and requires powercycling the duct to reconnect. I'm struggling to find in the description how to determine which unit comes with a dedicated remote controller, but I highly recommend getting the models where the remote control is included, if you can find one for the T6. Also, the remote for the T4 doesn't work for the T6, just so you know I tried. The only thing I don't really like is the power cord. The length is fine. I know it needs power, but it is unsightly and I haven't figured out a good way to hide it except for furniture or a plant to cover it. Also, the T6 fit perfectly in my duct, which was exactly 6" x 12", but the screw holes did not align with the standard duct cover, FYI. My nit to pick is that the native options to program the unit aren't very good. The thermometer on the booster itself is never accurate -- when the A/C is running it reads colder and when the A/C is off it reads hotter. It makes sense, but it means the temp-based programming is never accurate. I've tried the timer method, and it is the best of the included options, but it is still not ideal because if the A/C is off, it can blow hot air into the room. Because this unit appears to be only Bluetooth and only seems to be controlled by the app that doesn't play nice with anything else, I cannot program this into my smart home in any meaningful way to sync with the A/C thermostat in a way I can with the T6 that includes a remote control. Overall, I highly recommend these register booster fans.

Positives: It works. Looks nice and the bluetooth app controls were a nice plus. Negatives: Only 2 sizes available, power cable is less than ideal if your vents are high up. I got this fully expecting I might return it as I have read all sorts of negatives about "vent boosters". Our upstairs bedrooms are always 5-7 deg hotter than the main floor in the summer. We've done everything recommended (insulation, added bigger return, etc) and it's just how our 60yo house is made. The heat collects and that's all we got. I looked into a separate hvac system for the upstairs but that's $$$. A friend recommended vent booster fans. OK fine. I put a temp sensor in 2 bedrooms on the same side of the house. Both rooms stay about the same temp. After running the booster for about half a day, I found that room was only 1-2deg higher than the main floor. That was a huge difference, and I had the fan running at 70% to keep the noise down. The unit has a flow detector setting that turns the fan on when the hvac is blowing. It also has temp sensor activation (so you can run minimum/maximum hvac air flow temp activation) One cool feature is that the "off" setting can be tuned so the fan just runs at a lower speed. This is hugely useful because when the hvac turns off, there is still cold air in the duct. Having the booster fan run at a low speed keeps it pulling the trapped cold air. I set the "off" speed to 2/10 and it noticably helps. The unit display shows the air temp at the unit, not your room, so you can check if it is still pulling cold (or hot) air. One big negative is that they only have two sizes. 6x10 and 8x12. All of our vents are 8x14, so you can see what I did to fix that in the pix. I took an 8x14 return and cut the grill out, and drilled holes for the fan booster mount, then mounted it as normal. They *could* change the design so you buy the fan unit and the cover separately so they could offer many common sizes. There is no downside. The other big negative is the power cable. If your vents are low, it's easier to hide and you can run it along your base moulding, but all the vents in our house are high so -- oh well. Is it worth the price? I would say yes. It definitely boosted the cooling in our hot upstairs rooms and it's a lot cheaper than buying and installing a 2nd hvac system there.

Technically, the Airtap T6 works great. It helps pull more air into the area it is installed at. No, it won't make your entire house colder/warmer, but it focuses more of the conditioned air into a specific area. Say you have two rooms each outputting 50% of the AC for a total of 100%, you can change it with the booster to 60%:40% and make one cooler. There is a bit of a learning curve since the instructions aren't the best. To get the most functionality, you will need to download the app. Downloading the app actually gave me a better understanding of how to use it. There are a lot of settings that you can adjust. Why the low rating then? Not everyone's register is located at floor level. All the registers I've seen are near the ceiling. For some reason, the included cable is only about 6ft. This means the booster as it is provided will not work unless you have an outlet in the middle of the wall or near the ceiling. Given that there is a pretty substantial wall wart, you're not going to want to use an extension cable to connect from the wall wart to an outlet. I contacted AC Infinity customer support and asked if they had a longer cable and they said no. Instead, you're pretty much forced to buy a special DC barrel extension cable which is going to put you back about another $10 (search for something like "2.1mm×5.5mm, Universal 12v Power Extension Cable" at your approximate length. I've seen earlier reports saying a 12ft cable was included, so I have no idea why that was stopped. If it still had the long cable, this would be a 5 star.

The only thing positive about this product was the nice packaging. Immediately regretted purchasing this as I began installing it. I thought the vent feature being closed when the air unit isn’t being used was smart until I actually put it on my wall and realized the device always has to be on for the flaps to be open. THE AIRFLOW SOUNDS LIKE A DISTRESSED SIREN like humming air. It’s a little uneasy sounding the minute I set my airflow to 2. The max airflow speed was crazy sounding so I can’t get the full use out of this product. The remote makes an awful beeping sound that’s the sound of a microwave button/ ATM. I am returning this asap and purchasing a previous model from a different brand I bought a few weeks ago. The reason I bought this one was for the WiFi and app features, which is funny, I have not even cared to install the app because the machine makes so much noise. RETURNING IMMEDIATELY

******************************************************************************************************************** Update 11/9/2024: I found a way to make this device work with Home Assistant on a pi, but it will overwrite all settings you made with the phone app (temperature triggers, fan speeds, etc.). hunterjm created a bluetooth connection protocol for other AC Infinity devices, but it works with this vent booster after a few small modifications. Make sure that HACS is installed on Home Assistant and then you can search for the ac-infinity-ble integration by "hunterjm". After adding the integration, use the ssh & web terminal in Home Assistant to edit the config/custom_components/ac_infinity/ fan.py and sensor.py files. Manually type in a model name, manufacturer, and sw_version for both files before restarting Home Assistant and adding the device. You can see the temperature sensor value on a dashboard tile, but the fan on/off feature doesn't really work well. However, you can easily set the fan speed in an automation script. The "fan off" function does not work, so set the fan speed to 0 to turn off the fan. Now I have very reliable triggers for turning on/off the vent booster! When my AC or Heat turns on in the house, Home Assistant turns on/off the vent booster to a set fan speed. No more false triggers when the sun heats up the vent booster or a cold morning in the fall. ******************************************************************************************************************** The installation was easy enough, but it was a tight fit on this particular register because the fan profile went deeper than the original vent cover (and the metal walls on my house's duct were bowed inward slightly at the vent). The mounting holes didn't line up with my old vent cover, so I had to make new screw holes. Don't bother with the button controls on the unit itself. Download the app and configure it with bluetooth. It's much easier to see what's going on and is more intuitive. I turned off the lit display on my unit by pressing / holding the setting button per the instructions. At a fan speed of 6, this room with the longest run from the air handler is now keeping a more consistent temperature with the rest of the house, but you can definitely hear when it's running. I don't think it's necessarily too loud since it eventually becomes white background noise. I might back down the speed to 5 or 4 if anyone complains about it. The vent was on the ceiling, so I drilled a hole through the ceiling (but still concealed within the edges of the unit) to run the power cable up to an outlet in the attic. Just make sure it's well-secured with the mounting screws so it doesn't fall on anyone's head! I also caulked around the hole.

Our daughter's room is on the front of our house, which faces south, and is on the western corner; in the Summer, her room gets full, unobstructed sun all day until sunset. In the Winter, her room gets blasted by the frigid air from two sides (the wind in our area blows out of the west, so her room gets the brunt of it). Additionally, her room is at the very end of the HVAC run of the house, so the flow of air is very low. After doing some tinkering - I tried closing vents in other rooms (minimal effect) , and setting the thermostat to regulate off her room's temperature (AC/heat running way longer to cool/heat her room - big $ increase in our utility bill) - I purchased this booster. It made a HUGE, tangible improvement in the comfort of her room. You can feel the difference in the temperature almost immediately; her room stays markedly cooler in the summer and warmer in the winter. As others have noted, the settings can be a little counterintuitive, but once you get it set, it works really well. The app works well but you do have to be within Bluetooth range to make setting updates - which perhaps is my sole critique of this item; I would've preferred it to be Wi-Fi over Bluetooth so I could make updates remotely, but that isn't a huge deal. The fan isn't totally silent, but it doesn't bother us as our family all sleeps with fans/sound machines. It is audible during the day but isn't loud by any means. The first booster for our daughter's room has performed great even after a year of use. It works so well, in fact, we bought another one for our bedroom's vent. The unit itself is high quality and feels sturdy, and is a perfect fit for our vents. Overall, if you're in a similar situation, this booster really can't be beat. We got a nice discount on Prime Day for our second unit, but even at full price, I'd recommend giving it a try.
