Essential Info

Is there a room in your house that is usually cooler or hotter than the others? If so it is probably due to bad airflow from your vents. Airflow in central air homes weakens the further it travels through the ducts. The Tjernlund Cyclone Booster Fan Plus helps solves this problem. The Booster Fan boosts the idle air from vents outward into the rooms where it is needed most, making every room in your home equally comfortable. The innovative design features a built-in thermostat that senses heated or cooled air and turns the fan on and off automatically, lowering your heating and cooling costs year round. The Cyclone Booster Fan Plus helps SAVE ENERGY and MONEY, just set it and forget it.

The Tjernlund Cyclone Booster Fan Plus is also available in Brown, sold separately.

    It cools great, but after 2 days of being on, the first one we ordered started making a very harsh clicking noise, so we unplugged it. I tacked it up as a faulty unit, but in less than a week, the second one started making the exact same noise. I hope Smarthome will cover this and offer a different unit as an option, but 2 out of 2 broke in the first week. It's disappointing, because like I said, it cooled the room down great, and really moved a lot of air.
