Quietly Boost the Efficiency of Your Home's Air Register with the AC Infinity AIRTAP T4

Cobo: I had an idea to build up something like this to help increase the air flow in one of our bedrooms that is far away from the air handler in our A/C-furnace. I was pleasantly surprised that a product already existed that did exactly what I wanted.

Although it offers the ability to have two temperature thresholds that can be active simultaneously (to turn the fan on for heating as well as cooling), I chose to disable one of thresholds, at least for the cold winter months. The reason for that is because the bedroom where it's installed can become purposely cool at night during the cold months, and I didn't want that low temperature to trigger the fans to come on as they would do when the A/C is running. I was glad to see that it offers the ability to disable one of the thresholds; I will just reverse the setting when the warm months return.

I am quite sensitive and intolerant of noise when I'm trying to sleep. I was concerned the fans in this unit would be noisy. I have the fan set to a medium level and it's wonderfully quiet at that setting, yet still effective at pulling air through the duct.

The factory default settings keep the display on continuously. The...

AvocadoAmazon: I recently added the AC Infinity AIRTAP T4 Quiet Register Booster Fan to my HVAC system, and it has made a significant difference in maintaining a comfortable and consistent temperature in my home. I'm thoroughly impressed with this product, and here's why I highly recommend it:

Efficient Heating and Cooling: The AIRTAP T4 is a game-changer when it comes to heating and cooling. It ensures that the air circulates evenly throughout my home, eliminating hot and cold spots. It provides consistent and comfortable temperatures in all rooms.

Quiet Operation: This register booster fan operates quietly, which is a relief. It doesn't disrupt the peace and quiet of my home, allowing me to enjoy a comfortable environment without any noise disturbances.

Thermostat Control: The built-in thermostat control is a fantastic feature. It allows the fan to turn on and off automatically, based on the temperature of the room. This hands-free operation is incredibly convenient and energy-efficient.

Easy Installation: Installing the AIRTAP T4 was a breeze. It fits perfectly into standard 4" x 10" register holes, and the installation process was straightforward. I didn't require...

Blue: We have a room that is used as an office that also happens to be difficult for the a/c to effectively cool. This vent cover really just plops into place and is ready to go. The hardest part was playing around with the settings for when it would turn on, since it seems to measure temperature in the vent rather than in the room. It does help get more cool air into the room, but the fan can only do so much with what cool air makes it to the vent. It is a worthwhile purchase to help out on the really hot days.

Amazon Customer: I’ve had this product for almost a year. I have had no issues with it. I have a woodstove in my basement and I have put a vent above it which with the fan pulls more than enough air to heat the upper floor. On a sidenote, I found it, pulls the cold air from the basement during the summer to assist with the air conditioning. Hydro bill was down this year, considering it was so hot. I would buy it again.

Nicole: These vent fans are wonderful. They helped balance out my kids and the master bedrooms Keeping the upstairs a little more in line with the first floor. House was built in 1999 but the upstairs ducting seems to either just be lacking or is restrictive due to the long runs. These vents helped immensely. Also helped the Air conditioner from having to run excessive amounts as the first floor and basement would be cool, to freezing Respectively.

Bradley Simard: I ended up buying this product because HVAC companies continually failed to deal with unbalanced airflow in my house. Particularly all three upstairs bedrooms get really hot in the summer because there's barely any air coming through the ducts, while the main floor is freezing cold.

There's a few things that I think should be mentioned, though:

1. Noise
You can set the fan speed between 0 (off) to 10 (full blast). I need to set mine on 8 for it to make a noticeable difference in the airflow. This will obviously depend on your setup and how much air you're already getting to your problem vents. Anything above 5 is noticeable. Anything above 6 becomes noisy. I think they could've used 1 large fan instead of the 2 smaller fans or used higher quality fans that make less noise. Having said that, I'm fine with the noise level because my alternative is being uncomfortably warm when trying to sleep.

2. Configuration
The first time you configure this product, it might be a bit confusing. Basically it has a thermometer in it to register what the air temperature is in your vents. This does NOT measure the temperature in your room, just to be clear. What you do is...

MDiasMDias: I want to start this review off by saying AC Infinity has some reputable products that work great! Like the rest of the reviews on here, I was looking for a way to bring more cool air into my baby room during the hot summer months and on fan setting 5 this thing did the trick! I do have a few things that you might want to keep in mind!

Pros:
- Pretty much everything that's said in every review. It's easy to install, fits perfectly, and delivers a bunch of cold (or hot) air to the room that needs it the most. The fan can be very quiet and I don't find the loudest setting that loud (we have an air purifier that is 10x louder than this vent).
- Customer service is helpful!

Cons:
- You can't close this vent. There are instances where we had to close our vent because the room in the winter was too hot when the rest of the house is cold. Well, it's not possible without purchasing a vent cover. Not a big deal but something to think of.
- Everyone states programming this device is easy, which it is, but I find it's not intuitive. You need to program the device for what the temperature of the room "would be" after the A/C or Heat are on at the temperature of the...

Darren Flewelling: So I have a lot to say about these it turns out.

I ordered two, to replace a pair of registers that heat two colder upstairs bedrooms of our pre-war home, and I know the duct takes a convoluted path, before popping up through the common wall. It always had poor air flow, even after we upgraded our furnace last year.

So these boosters are now installed 4 inches across from each other, same duct, but the thermostats never match, and they are 3 to 5 degrees C higher than the max reading on my Laser thermometer says they should be. Normally woulnt care, but because they don't even match each other, tuning the setpoints is extra challenging because I want them to turn on together so they pull air from the duct, instead off the opposite room. One is saying it's 26 right now, but laser scanning register and duct reads max of 21, and room itself is about 17.5.

The other thing I don't like is how they glue foam to the cardboard packaging. Not sure why they do this but it is so annoying if you want to recycle your packaging (pretty standard these days, no?). One foam peeled out okay, but I literally to to scrape the foam out of the other cardboard package, where the...
