DUCT-PRO® enables professionals to offer duct cleaning as an add-on service, which can lead to more business opportunities and higher revenue. 

It’s important to understand the role each piece of equipment plays in the process before starting a duct cleaning business. Our team of Aire Guardians at Abatement Technologies® has created a video series to provide users with the key information needed to safely start using DUCT-PRO®. We’ve created a blog series to accompany our training videos and help break down the process for using DUCT-PRO®. In this blog, we’ll discuss the proper accessories and equipment needed for the job as well as the necessary prep work for their optimal performance. 

DUCT-PRO® Accessories & Equipment 

We recommend beginning any duct-cleaning project with personal protective equipment (PPE) including safety glasses and respirators. Additional recommended PPE includes cut-resistant gloves and sleeves to reduce injuries when reaching through ductwork with sheet metal cutouts. 

Once the proper PPE has been identified, it's time to identify which duct cleaning method is right for the job. Our  DUCT-PRO® system uses the state-of-the-art source removal duct cleaning push/pull method. The “push” mechanism is achieved with high-velocity compressed air tools while the “pull” mechanism is accomplished by creating powerful airflow through the air conveyance system with the use of the HEPA-AIRE® portable vacuum included in the DUCT-PRO® package from Abatement Technologies®.

Duct Cleaning Prep Work

Next ensure the furnace, AC, and duct systems are turned off and will remain off for the duration of the project. It’s also good practice to turn off the air handling unit at the thermostat as well as the circuit breaker to prevent accidental startup. It’s important to be aware of, and adhere to, all local regulations regarding gas pilot lights and other utilities before beginning any project.

The duct cleaning professional should conduct a thorough inspection of the project site to identify any potential safety concerns and determine the layout of the ductwork once the systems have been turned off. During this process, the duct cleaning professional will examine the condition of the ductwork and determine the type of air handler used so they can develop a plan for hookup points and air sweeping procedures. It’s important to understand how to clean the supply and return duct networks to avoid pulling debris through the heat exchanger and coil. To separate the supply and return, simply pull out the furnace filter and insert an inflatable zone bag into the air handle to isolate the supply and block airflow. 

Grill masking tape should be used to seal off the registers and increase airflow through the branch being cleaned. It’s important to keep the furthest two or three vents uncovered during this step to allow air into the ductwork to create airflow. The airflow will be inadequate for transferring debris to the power vacuum if all vents are covered.

Our DUCT-PRO® HEPA-AIRE® portable vacuums are designed to pull large volumes of debris through the duct system and filter all of the contaminants before exhausting clean air from the vacuum. For optimal performance, the vacuums should be placed as close to the furnace as possible. 

When the filters become dirty, audio and visual alarm cues will signal that airflow has been reduced and it’s time to change them. Most operators prefer to change the HEPA filter every one to two years of use.

Managing IAQ in Commercial Building During Wildfire Season

Managing IAQ in Commercial Building During Wildfire Season

Topic: 2023 Central Canada Wildfires

The 2023 wildfire season is here and has already had a devastating impact across central Canada. As hazy and dangerous fumes make their way south across the US border, most of the Northeast coast is experiencing serious air quality issues that are affecting millions of people. And, because smoke is made up of a complex mixture of gasses and fine particulate matter, it is highly inhalable and can cause respiratory and cardiovascular health effects. 

But, when a smoke event occurs, it can take days to weeks for air quality to improve. If not properly addressed, smoke can get inside of buildings and negatively impact indoor air quality (IAQ).  Building owners and facility managers need to know the best practices for reducing exposure to smoke inside offices, schools, and housing facilities.

Facts about IAQ

Outdoor air, including the fine particles from wildfire smoke, can enter a building in a few ways, including: 

- Natural Ventilation: Open windows and doors

- Mechanical Ventilation: Bathroom fans, kitchen fans, and HVAC systems with fresh air intake 

- Infiltration: Openings, joints, cracks

When smoke events occur, local and state health departments may issue air quality alerts notifications when specific actions are needed to protect the public. Building managers should use these notifications to know when to initiate mitigation measures in their smoke readiness plan, which should include these steps: 

1. Evaluate the HVAC Systems

To minimize occupant exposures and health impacts from smoke during wildfire events, facilities should first address any issues with their existing HVAC systems. In buildings where the HVAC system uses air-handling units that bring outside air into buildings or recirculate indoor air, facility owners and managers should follow a planning framework, like the guidelines set by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE).  This includes: 

- Performing maintenance on HVAC

- Upgrading filters

- Optimize system airflows 

- Adding supplemental filtration 

- Limiting areas for smoke intrusion 

- Adding the ability to monitor particulate matter

- Assessing how to create cleaner air

2. Stock up on portable air scrubbers

Additionally, those in areas prone to fires may consider purchasing equipment to improve IAQ during the duration of a smoke event. Portable air scrubbers, like  our PRED750, are self-contained air filtration devices that can be used alone or with central air filtration to effectively remove harmful particles from the air.The portable air scrubber should be equipped with a high-efficiency HEPA filter and be the right size for the room. It’s important to secure these crucial devices before a fire occurs in order to act quickly during a smoke event. In the event of emergencies, it’s important to find an air scrubber supplier that has the ability to ship orders as quickly as possible.

3. Choose the right filter 

Some air scrubbers are compatible with activated carbon filters.These filters are available for  all of Abatement Technologies’ HEPA-filtered equipment, including the PRED750 mentioned above. Activated carbon is a unique material that is often used to remove volatile organic compounds (VOCs), odor, and other pollutants from the air, making it the optimal solution for smoke filtration. The benefits of activated carbon filters include their ability to adsorb a variety of vapor contaminants, organic molecules (especially solvents), and chemicals, as well as their large capacity to catalytically destroy ozone, a major component of smog. 

In addition to smoke, Abatement Technologies’ portable air scrubbers and carbon filters have been used to filter out a number of odors from buildings including chemicals, cleaning solvents, mildew, mold, and biohazards.

5 Years Later – How Abatement Technologies Aided Hurricane Maria

September is historically the time of year with the most optimal conditions for the formation of hurricanes in the mid-Atlantic region. Because of the high amounts of humidity and warm air in the Caribbean, its geographical location houses the perfect conditions for catastrophic hurricanes. In fact, this year marks the fifth anniversary of Hurricane Maria, the deadly Category 5 hurricane that devastated the northeastern Caribbean in September 2017.

As a result of Hurricane Maria, the island of Puerto Rico lost most of its essential services’ infrastructure, communities were leveled, many were displaced, and thousands of lives were lost. Five years after the disaster, the reconstruction and restoration efforts on the island are still ongoing. Following the immediate devastation in 2017, Abatement Technologies customer and restoration expert, Pat Dooley, was contracted to fly to San Juan, Puerto Rico, to do an assessment of the flood damage in the Mall of San Juan, a 1,580,000 square-foot shopping mall that first opened its doors in 2015. Upon initial assessment, Pat and his team discovered that nearly 18 inches of water had flooded the mall.

As a result of the hurricane, there were travel and equipment delays that prohibited Pat and his team from arriving in Puerto Rico until 14 days after the hurricane had already passed. Because mold incubates from a spore for 12 to 24 hours, and starts showing visual signs of growth in 48 to 72 hours, the team was challenged upon arrival with remediating severe mold growth. When remediating mold, it’s important to remove every spore to prevent regrowth. Because of this, workers had to cut and remove drywall and other materials, which lead to dust and other potentially harmful particles in the air.

In order to safely contain the mold, Pat and his team decided to bring in 100 of Abatement Technologies’ air filtration devices. These devices were situated throughout the mall to help remove any harmful particulates, bioaerosols and volatile organic compounds that were released into the air during the project. By leveraging this equipment, the team was able to help protect the short and long-term health of those involved and helped ensure that they were breathing the cleanest air possible. 

As a remediation and restoration expert, Pat is an IICRC Instructor and is the founder of what is known today as the Applied Structural Drying Course. Leveraging his education and experiences, like the project in Puerto Rico, Pat has carried out water restoration projects with a total value of nearly $14.7 million and has participated in numerous natural disaster restoration projects. With a passion for helping and protecting people, Abatement Technologies is proud to work with remediation and restoration experts, like Pat, to deliver the best solutions available in the market.
