The answer, my friend, is blowin' in the AC VIVOHOME HVAC Register Booster Fan. It's a quiet fan system with an LCD display, smart thermostat control, and customizable fan speeds that looks and fits in place like your standard wall or floor register, but uses its built-in blowers to increase the warm or cool air emitting from your ducts. The booster system is especially useful for registers with weak airflow, and perpetually cold wives who insist on setting the thermostat at 76 in the winter because they "can't feel any heat coming out! Is it even on?!"

Each booster vent has an on-unit controller with active thermal monitoring that's responsive to your temperature settings for both cooling and heating boosts. The boosts come from a high-efficiency EC motor VIVOHOME says is able to deliver up to 120 CFM airflow at 10 different fan speeds, all ultra-quiet at below 18 dBA. Vents also have oscillating louvers that rotate between 60 and 120 degrees.

HVAC Register Booster Fans come in 3 common register opening sizes.
