Best Register Booster Fan for Air Conditioning Systems
The summer can get a little too hot, especially during the day. This is where booster fans come in handy in the house; they help boost airflow by providing cool air to get rid of that excess heat. However, if you are looking for the best register booster fan, you need to select the right booster fan for optimal performance.
The two major types of duct boosters are register fans and mid-duct fans. A duct booster, also known as an AC duct booster, is designed to move more air from the ductwork of the HVAC system to where it's needed. The fan blades of a duct booster will pump cold air-conditioned air into the room so that it can get to a comfortable temperature much more quickly.
Many register booster fans brands claim to be the best in the market, including some that will perfectly fit into the vent openings. This, therefore, means that trying to determine what's best for your home can be a little more difficult than you'd assume.

Frequently Asked Questions on the Best Register Booster Fan
1. What are the cons of using register fans and mid-duct fans?
Register booster fans
Register fans, many of which have been reviewed in the above section, are simply small fans on the register, placed in the problematic area of the room. Most of these register fan models come with their own speed adjustment and thermostat setting. Furthermore, you can control them remotely, which is more convenient for some people.
Some of the drawdowns of using register fans include:
- A lot of noise
- Might fail to work
- Needs an electrical cord to work
- Block air vents in the building and end up restricting air movement
Mid-duct fans, also known as inline duct fans, are large and cylindrical in shape. Ideally, this makes inline fans fit inside the building's air ducts halfway between the HVAC systems source and the area with the problem to pull air either heated and cooled air. Some of the downsides of an inline fan include:
- Needs an electrical outlet or hardwiring
- Needs a relay back to the HVAC system
- You will need an experienced electrician or HVAC system technician to help with the installation process since you will need to expose the HVAC dust to install
2. How many CFM do the best register boosters have?
To cool air flow for a room with two supply registers, you will need to divide the base supply CFM between these two registers to find the airflow of each supply register. The living area requires a base supply of roughly 180 CFM, which means that each supply register should have 90 CFM.
If you have a rectangular duct of 10 x 12 inches, 2000 CFM of air can flow through; on the other hand, 100 CFM air can flow through a 6' duct handle. This then means that you need 50 CFM for roughly 1,000 square feet, 100 CFM for at least 2,000 square feet, and 150 CFM for 3,000 square feet. Based on this calculation, you will need 1 CFM per square foot of room area, and to find the square footage of your room, you will need to multiply the length by the width.
