What Is a Duct Booster?

installed register booster fanA duct booster also called an AC duct booster is designed to move more air from the HVAC system’s ductwork to the desired space. The fan blades of a duct booster pull conditioned air into a room so that it can reach a comfortable temperature quickly. There are two major types of duct boosters and they include:

  1. Register fans
  2. Mid-duct fans

Register Fans

We’ve reviewed many of these in the above section. Register fans are simply small fans on the register in the problematic area of a room. Most of the register fan models come with their own thermostat setting and speed adjustment. You can also control them remotely. Some of the drawdowns of register fans are:

  • Too noisy
  • They are prone to failure
  • Need an electrical cord
  • They block vents, thereby end up restricting airflow

Mid-Duct Fans

These are also known as inline duct fans. They are large and cylindrical, which makes them fit inside the ductwork halfway between the HVAC source and the area with the problem. Some of the disadvantages of mid-duct fans include:

  • They need hardwiring or an electrical outlet
  • They need a relay back to the HVAC system
  • They need an experienced HVAC technician or electrician for installation since the HVAC dust must be exposed for installation.

What Is a Register Booster?

These are small fans that sit directly in or on the register in the problem room. The good thing about a register booster is that it’s easy to install and cheap.

They usually cost less than $100 and they come in different colors. They have their own thermostat and they are also multi-speed, plus you can control them electronically. These ideal features make them easy to use in your home.

Some of the advantages of a register booster are that it can be noisy and prone to frequent burnout. Also, since it comes with an electrical cord, it tends to be cumbersome because you always have to find a way to plug it in.

A register booster doesn’t cure underlying defects but only helps to boost the airflow of your current HVAC system. If you want to properly distribute airflow in your home, register boosters can be an ideal option to consider, since they are efficient, cheap, under-friendly, efficient, and affordable.

Do Register Booster Fans Work?

Absolutely! Register booster fans do work and they can provide you with the best solution. The main objective of register booster fans is to help pull air out of the ductwork and into a room. Although they can’t help you solve the airflow issue on their own, they are a cost-effective way to circumvent more expensive repairs.

However, if your HVAC system happens to have an issue, a register booster fan may have little to no effect in terms of boosting the airflow. Therefore, you need to consider this factor before investing your money into buying this product.

Even if you buy the best register booster fan on the market, you need to ensure your HVAC system is working properly for the booster fan unit to be effective.

How Many CFM Is a Register?

If you have a room with two supply registers, then you will have to divide the base supply CFM between the two registers to find each supply register’s airflow. The living requires a base supply of 180 CFM, which means each supply register is supposed to have 90 CFM.

2000 CFM of air can flow through a 10 x 12 inches rectangular duct, while 100 CFM air can flow through a 6 duct handle. Therefore, you need 50 CFM for 1,000 square feet, 100 CFM for 2,000 square feet, and 150 CFM for 3,000 square feet.

Judging by this calculation, it means you need 1 CFM per square foot or room area. To find the square footage of your room, all you have to do is multiply the length by the width.

Where Should a Duct Booster Fan Be Placed?

If you want optimal performance and minimum noise, the best place to install a duct booster fan is in your in-line duct fan, usually midway or between the blower and the vent that serves the room. For the best installation, you need to seek the assistance of a professional.

An inline duct booster fan mainly helps to pump air through the ductwork in your home. The benefit of an inline booster is that it’s quiet, efficient, but more expensive compared to a register booster fan. Whether the duct booster fan will solve your problem or not depends on the status of your home and HVAC system.

If your ducts are leaking, they are poorly designed, or your HVAC system is not the right size, installing a duct booster fan may not have such a big impact.
