When Should You Use a Duct Booster Fan?

If you have issues with irregular heating or cooling in your house, an HVAC booster fan may be the perfect solution to meet your needs. The signs of an imbalanced heating or cooling include temperatures that differ across different areas of your house or uneven temperatures across the different floors in your house or rooms that are crowded.

1.HVAC System Is Too Small for Your Home

A malfunctioning HVAC system may cost a lot to repair. HVAC devices that are too small or large can creates a number of issues. Systems that aren’t big enough or too large are unable to provide adequate heating or cooling, rendering your house uninhabitable in all temperatures.

  1. Air Leaking From HVAC Ductwork

The ductwork within your home is used to transport clean air of the HVAC unit to the rooms of your house. Any leaks that occur within your ductwork may make it more difficult to effectively transport air. The most frequent causes of air leaks within your ductwork is unfit joints, seams, joints or fixtures as well as the peeling of the tape covering the ductwork connections and ductwork tear and more.

In the event that air leaks led to the formation of cold or hot spots in your ducts and home the installation of a duct-boosting air conditioner isn’t going to fix the problem. Some of the most popular methods for battling air leaks inside the ductwork is to use insulation and duct tape or using liquid sealants.

  1. Blocked or Restricted Ductwork

Because your HVAC system is dependent on the ductwork in your home’s ductwork to circulate heated air throughout your home and the ducts must be clear of obstructions. The accumulation of dust or other debris that is too large smaller animal (or rodents) within the ducts, or objects that have a tendency to crush the ductwork could cause obstruction of airflow.

All of these are issues that can be solved by the HVAC booster fan can’t seem to fix. After you’ve solved these issues and are able to make an informed decision about the need for an AC-duct fans booster. If yes, you’ll need to decide on the kind of booster you’ll require.

Types of HVAC Booster Fans

There are two types of HVAC booster fans, one that is inline-duct-based as well as a register fan.

In-Line Duct Booster Fan

They are also referred to as mid-duct fans. These fans have a cylindrical shape and can be found into the ductwork. They usually serve to replace the section of ductwork. You can pick any spot between HVAC systems as well as any room that has problems with heating or cooling.

Some models are utilized as plug-and-play Duct boosters, they typically require an electrical outlet or hardwiring.

In-line duct fan are generally located near to a vent within the fan unit. This helps to circulate air throughout the system and keeps the heated air from exiting the vents that are closest to it.

Because these duct fans require cutting off sections of your ductwork, you’ll need employ an professional to install them. Engaging an electrician can increase the initial cost of installation, but it’s essential since you’ll need an air conditioner that’s in line with your existing ductwork. After installation the duct booster won’t require any energy.

Register Booster Fan

A different option which is less expensive than the in-line, duct booster could come in the form of an alternative to the Register booster fan, which is sometimes called ” in-the-register” fans. Register fans are devices that plug and play which are easy to set up and operate. Contrary to an in-line boost, this kind of fan can be set in rooms in which more airflow is needed.

Register fans are a replacement for existing ceiling, wall, or floor ceiling registers. They cause a pressure differential to permit greater circulation of air throughout the ventilation. While they’re louder than mid-duct models but they’re the best choice for homes with just three or two rooms are affected by airflow issues.

In-Line or Register Booster Fan: Which Is Better?

The two types of booster fans come with advantages and disadvantages. The decision you choose will be based on the purpose you’re planning to use them , as well as the equipment you have. For example, register fans are great for smaller rooms. They’re a great option for offices in smaller spaces or homes.

In-line boosters for ducts are great for ducting systems for instance, massive commercial structures. Commercial spaces with larger sizes and more complex and intricate ducting systems, a single blower won’t be enough and a number of units are used to increase airflow in any place.

CFM Capacity

Cubic Feet Per Minute (CFM) is an HVAC gadget which measures the efficiency of a fan through measuring the airflow. It calculates the power of air exchange in an air-flow fan by taking into account the space of the cubic space and the rate of airflow in the room.

In general use one CFM is required for each sq. ft. of floor space. You can calculate CFM yourself also. CFM yourself using this simple formula that considers the ceiling height of the room and area of the room, and the amount that air changes every hour (ACH).

Static Pressure

Simply put The static tension of an air conditioner is the volume of air pressure it is able to generate within the enclosed space. This is a crucial aspect to take into consideration when choosing the most suitable fan for ducts.

To ensure that you’ve made the correct choice, you’ll have to evaluate the static pressure in the area prior to selecting the most efficient model and keeps the static pressure steady within the area. This is done the use of an instrument, but most HVAC booster fans are fitted with the same amount of pressure that is listed on the package. Find the duct booster with a static pressure which is less than 2″.

Loudness Limit

Duct boosters typically produce a lot of sound. However, certain fan models and variations are quieter than other models. For instance In-line duct-boosting fans are generally quieter than registration fan designs. This is why it is important to pick HVAC or duct fans that has the right level of noise.

In-line register fans are more expensive and register boosters are more expensive. They cost between $30 to $200. The more expensive models feature more sophisticated controls and an electronic display. While the initial cost may appear reasonable, the installation costs associated with these fans can increase by $600 on your amount.

Register fans aren’t as costly than the other two however an in-line duct booster can solve several rooms’ heating and cooling problems. However register fans are only suitable for a single space. This means that you’ll require another registration booster to each space that you’re trying solve heating or cooling issues.
