Furnace boosters, or register boosters, work with forced air furnace and central air conditioning systems to improve airflow in rooms that are hard to heat or cool. These boosters are designed to fit into standard forced air wall or floor registers and plug into the nearest outlet to boost your central AC/furnace system's output. Furnace boosters are easy to use and save energy too, by turning on and off automatically. Make the most of your heating and cooling system by giving it a little boost.
