## Description

A quiet fan system designed for improving wall and floor vents airflow from HVAC systems to increase home comfort.

Review: I have grown to love these... if you want a little boost, you can get them down to quite quiet, if you need to pull more air it can do that too, and still quite manageable. I like how it turns on and off when the a/c or heat is on! The casing is attractive, and the display turns off when you're not using it (so no extra light in the room when trying to sleep). Good job folks. Simple, reliable and attractive.
Review: It's ok, doesnt have as much power as we were hoping. We will see in the summer of it does what we want it to do.

### ⭐⭐⭐⭐⭐ Review
*by J***W on 15 May 2025*

I have an upstairs that runs too warm all summer. It's big room with one vent fed by at least a 15 foot run of 12" duct. I had been planning to sever the duct and install an inline duct fan up in the attic and either use an expensive pressure switch or tap into the thermostat wire with a relay, but this vent register booster is a much easier to install and less expensive solution - and it's working pretty well! Plugging it in is the only tricky part, but I was able to plug it in up in the attic so no cord is visible. I took my old vent register off and I probed around the edges with one of those wiring fishing rods until I found a gap where the rod could push up into the attic. Then I climbed up in the attic, plugged it into an outlet up there and then taped the end of the cord to the rod so I could pull it back down into the room. The AC register booster has a short 6 inch lead attached to it, and the rest of the wire connects to that. It's obviously heavier than a plain vent register, so it was bit difficult to install because I had to use both hands to hold the register up there and connect the wire and then reach for the screw and screwdriver to fasten it in place without letting go of anything. The thermostat measures the air in the duct so that you can set it a temperature below the normal room temperature, but above the temperature you're reading in the vent when the AC is on and it will turn the fans on only once the cold air starts coming through. Mine started off reading 68ºF in the duct, but after a while I checked it again and the reading was 66º, so I figure it's pulling the cool air through the duct faster and not allowing it to heat up in that long duct in the attic. I still need to replace my AC system, but I can tell that this room is noticeably more comfortable after installing this inexpensive solution first.
