Duct-Booster Fans

If you have forced-air heat, you can take advantage of several types of duct booster fans that are designed to increase the flow of warm (or cool) air through your ducts into a problem room. In-line duct booster fans fit inside standard-size metal ducts. You mount the blower near the outlet end of a duct and then install a pressure switch (some models have one built in), which senses air pressure from the furnace and turns on the booster fan whenever the furnace or A/C blower turns on. Some in-line duct boosters simply plug into an available outlet, while other models are hard-wired. Cheaper units can be noisy, so it’s worth buying a quality model with a powerful motor and heavier gauge housing.

A ‘register’ booster fan is much easier to install. Depending on the model, it either sits on top of or replaces a floor or wall register grille, and plugs into an outlet. A built-in thermostat switches on when the furnace operates. Register duct boosters cost $40 to $70. Many different manufacturers make duct booster fans of both types.
