Register Airflow Booster - HVAC Boosters

These Register Boosters allow you to enhance the airflow to underperforming registers and increase airflow up to 85%. Our Thruwall Fans efficiently move air from room to room quietly and are hard wired into your home electrical system. Lastly, our Entreeair Door Frame Fan allows you to circulate warm air from a room with a fireplace or cool air from a room with a window air conditioner while saving you on energy and money!

"Why do I need a register booster?"

A register booster is a great solution for a register that just doesn't push out enough air! For whatever reason, be it clogged HVAC systems or your furnace, in some rooms air from the vent doesn't push out enough, making your room either too cold in the winter or too hot in the summer. We do have a register booster that replaces your existing vent, and there is also a register booster that simply sits on top of your existing vent. It helps circulate air and give the room a stronger airflow coming from the vent.
