    Commercial Air Duct Cleaning

    Regularly cleaning building air ducts can improve air quality, lower energy costs, and extend the life of your HVAC system. Dirty HVAC ductwork and components can decrease the system’s ability to deliver hot or cold air, make the system prone to failure, and lead to higher energy bills. Cleaning an HVAC system can increase the system’s efficiency up to 30%.

     Dirt, dust, debris, and microbial growth accumulate inside a building’s ductwork daily. These conditions create a potential breeding ground for mold, mildew, fungi, and bacteria that can cause health issues. Clean air promotes a healthier work environment that can increase productivity and reduce sick days.

    Contact Armstrong Duct & Vent or call us at 1-603-627-7016 or 1-617-651-1937 to set up an appointment or learn more about our Commercial Air Duct Cleaning Services.

    Meets NADCA’s strict cleaning requirements

    Armstrong Duct & Vent is a member company of the National Air Duct Cleaners Association (NADCA) and follows NADCA’s stringent cleaning standards. We use the NADCA’s source removal technique that utilizes large negative air machines, mechanical brushes, and compressed air tools specially designed for each type of duct system. The process includes no chemicals, disinfectants, and masking of smells because there is no need with this thorough cleaning method.  

    Armstrong has been a member company of NADCA since 1990 and is one of its oldest members. We were an early adopter of NADCA standards and its code of ethics in serving customers.  Armstrong is one of the few companies in New England that holds all NADCA certifications. One is the Air Systems Cleaning Specialist (ASCS,) which includes Ventilation System Mold Remediator (VSMR), and the other is Certified Ventilation Inspector (CVI). Armstrong Duct & Vent has the most NADCA-certified staff members in NH and in much of New England.

    Our NADCA-certified duct cleaning technicians take great pride in their work and make sure that your building’s duct work is thoroughly cleaned.

    State-of-the art duct cleaning equipment

    With our array of equipment, Armstrong Duct & Vent can work in any environment, including high-rise buildings and secure areas such as correctional facilities, high-tech offices, and  healthcare and government buildings. Our tools and cleaning procedures achieve the same level of clean that could be achieved by contact vacuuming every square inch of the ductwork, leaving our customers with clean ducts and cleaner air.

    Our special duct cleaning equipment includes:

    • Gas and Electric-Powered Air Compressors and Nitrogen Air Tanks: Delivering high volumes of air up to 180 psi, this equipment powers our remote-reaching air tools.
    • Vacuums/Air Movers: Powered by gasoline engines or high-powered multi-motor electric vacuums with HEPA filtration, our machines provide the suction to turn your HVAC system into an extension of the vacuum, moving upwards of 5,500 cubic feet per minute (CFM) of air. Our process ensures that your duct system is always under negative pressure, preventing any blowout or contamination of the space(s) we are working in. We have a large fleet of vacuums to accommodate cleaning extra-large ductwork and/or highly complicated duct systems.
    • HEPA Air Scrubbers: These ensure that extra-sensitive work environments stay clean of any dust or debris.
    • High-Power Rotary Brush Systems and Remote-Reaching Air Tools: These are outfitted with air blades, whips, and nozzles and are strategically inserted into access points in the ductwork to brush, scrub, and agitate the interior duct walls. These tools work with the high-powered vacuums to create a push-pull cleaning technique to remove all debris from the duct system. 

    Other duct related services

    Assessment and Sampling: If you are unsure if your building’s air ducts need cleaning, we can test and determine the condition and contamination of your air ducts and HVAC units. This testing is done to the most current ACR standards developed by NADCA.

    Video Inspection: Using specialized cameras, we can conduct a video inspection of your building’s air ducts to determine the level of dirt and debris in the ducts and if they need cleaning. Learn more about our Duct Video Inspection services here.

    HVAC Filter Changing: Our technicians can change the filter in each HVAC unit as needed.

    HVAC Unit Cleaning: We can clean the inside of your HVAC units, as well as service the internal insulation and the A/C coils.
