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. Review: Works to cool the room for sure. - I have an upstairs bedroom with a north window that was always too hot. Even setting the HVAC system fan on "continuous/high" it was 79-80 degrees in late afternoon when the sun hit the window. Keeping our HVAC fan continuous/high, I experimented with the options on this unit. Having the fan on this booster set at max speed (5) did cool the room to 74-75 degrees on a hot sunny day. The cool setting worked as well and I could set the fan to the max speed, also. Note the small area for the thermostat so it doesn't block the vent much. This measures the temp IN THE VENT. I set it at 75 degrees so anything lower than that and the fan would operate. Higher that that it will shut off. This unit is 200CFM where the others are lower so that really helps move more air. The light can be turned off and the unit still works as set. It installs easily. It's a little noisy at speed 10, but it gets quieter when the fan is on lower settings. If on the "Cool" setting, the fan comes on and off automatically, but it soft starts and the noise gradually increases. ## Features - Quiet Register Booster Fan: A quiet fan system designed for improving wall and floor vents airflow from HVAC systems to increase home comfort.

Came broke. *by M***W on July 31, 2025* Product came damaged but functions. Build quality is not great. As for the functionality the unit works good. There is a noticeable difference in room temp. We bypassed the temp range and went right for the direct fan speeds. Level 10 moved a lot of air, but is a bit noisy. Not horrible, probably half the noise of a box fan. Anything less that level 5 seems like a waste. The temp range works and I look forward to using it this winter to help with temperature differences in each room. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/640123757-register-booster-fan-for-6x10-inch-register-holes-white](https://www.desertcart.us/products/640123757-register-booster-fan-for-6x10-inch-register-holes-white) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-11*
