If one room in your house is constantly warmer than others and the air-conditioning vent just doesn’t seem to produce the airflow it should, you might need a register fan. These handy doodads give your vents a little bit of a boost, but that extra air can make a huge difference in the comfort of a room. In fact, it can actually help you cut down on utility bills, since you won’t need to turn the thermostat so low to keep That One Problematic Room cool. Also cool? The AC Infinity AirTap is on sale at Amazon right now.

Why do I need this? 🤔

A register fan can go a long way toward improving your home’s livability — and your sanity — in the swelter of summertime. For starters, it plugs into an outlet. The lack of batteries means you don’t have to constantly replace them to keep the fan running. It uses two 92-millimeter fans to push air through the home without the need for excessive speed, which means it can operate quietly. So if you’re worried that it’ll add an annoying hum to the background, don’t be. That said, there are ten different speeds and the higher settings are loud enough to make a sound, but the fan only activates those if you’re getting next to no airflow from your vent.

How’s this for convenient? After you’ve programmed the room’s ideal temperature via the touchscreen panel, the AirTap constantly monitors the air temperature and will activate when necessary to sustain your chosen number.

The Infinity AirTap is available in two sizes and colors — 4″ × 10″ or 4″ × 12″, in bronze or white. With the heat destined to reach oppressive levels any day now, this is a great time to give your HVAC system a little bit of a boost.

What reviewers say 💬

More than 5,900 AirTap owners say this vent fan has made a difference in their home.

Pros 👍

For some, it made the difference between a sticky and serene night’s sleep. “Our bedroom has always been noticeably warmer than the rest of the house, and we struggled to find a solution,” shared one ecstatic homeowner. “It has transformed our bedroom into an oasis of coolness, finally providing the comfort we’ve longed for.”

Said this satisfied slumberer: “I was having the worst trouble sleeping because my room was too hot and the vents just weren’t kicking enough AC into the room. We tried closing vents and still wasn’t that great … but then we purchased this, and I have been sleeping like a baby!”

With this current Amazon markdown, don’t be surprised if you save money in more ways than one. “This unit works wonders,” reported this reviewer. “It doesn’t solve the issue completely, but there’s a much more even temperature differential. And it’s saved a lot on the energy bill.”

Cons 👎

If technology intimidates you, know that there can be a bit of a learning curve to the display. “The only downside is that the digital display isn’t immediately user-friendly but you get used to it quickly. If your rooms are too hot, get this. You’ll be more comfortable in a blink.”

Oh, and about that LED display … “My only complaint is that the light it puts off is a bit much at night. A bit of tape over the display did the trick but it’d be nice to have a way to dim that in the evenings.”

Available in bronze and white, these fans are a great way to make your home more habitable without your having to shell out for a new HVAC system.
