At AQ International, we understand that optimally functioning ventilation systems are essential for a healthy and energy-efficient work environment. Cleaning, balancing and air sealing ventilation ducts are important steps in ensuring a healthy indoor environment and improving the energy efficiency of your building.
At AQ International, we distinguish ourselves by providing a total solution that goes beyond duct cleaning. We offer an integrated service that includes adjustment and air sealing of the ventilation ducts, so that your ventilation system performs optimally.

Cleaning, balancing and air sealing ventilation ducts offers numerous benefits that contribute to a healthier, more energy-efficient and safer working environment. Here are the main reasons to integrate these services.
Cleaning ventilation ducts removes dust, grease, mold and other contaminants that have accumulated in the ducts. This results in cleaner air and a healthier indoor environment, which is essential for the health of occupants or employees. In addition, ventilation system balancing ensures that air is properly distributed in all areas of the building, ensuring consistent and healthy air quality.
Clean and properly adjusted ventilation ducts cause the ventilation system to use less energy. When ventilation ducts are clogged or poorly adjusted, the system has to work harder to move air. This leads to higher energy consumption and operational costs. By not only cleaning the ducts, but also adjusting them properly and making them airtight, we can reduce energy consumption by up to 40%, resulting in significant savings.
Contaminated ventilation systems can be a fire hazard, especially in environments such as kitchens or industrial settings where grease and oil accumulate. Air sealing prevents unsafe air flows that can promote fire. Controlling air flow rates ensures that there are no uncontrollable air flows that increase the risk of fire.
Cleaning the ducts and adjusting the system properly reduces wear and tear on the ventilation system. Air sealing the ducts prevents air leaks that lead to inefficiency.
When the ventilation system is dirty or improperly set up, it can lead to airflow imbalance. This means that some areas of your building may be overventilated, while other areas receive inadequate ventilation. By adjusting the airflow rates, we ensure that all areas are evenly ventilated, which improves the effectiveness and energy efficiency of the system.
At AQ International, we offer a total solution for cleaning, adjusting and air sealing ventilation ducts.
This process consists of the following key steps:
We start with a thorough inspection of your ventilation system. Using advanced technologies such as camera inspections, we can accurately analyze the condition of the ventilation ducts and airflow rates. This helps us understand where improvement is needed and which ducts need to be cleaned, adjusted or made airtight.
During inspection, we use advanced methods, including camera inspections and, where relevant, the adhesive strip method. This method allows us to visually and quantitatively assess dust accumulation in a standardized manner, which is essential for an objective evaluation of ventilation duct contamination levels.
Our method is based on the guidelines of the NVRL (Dutch Association of Cleaning Specialists for Air Ducts), and takes into account the European standard EN 15780, which establishes the criteria for the cleanliness of ventilation systems in non-residential buildings. So you can be sure of an inspection according to recognized and reliable quality standards.
After the inspection, we begin the thorough cleaning of ventilation ducts. We use rotary brushes, negative pressure techniques and air purification systems to effectively remove dust, grease, mold and other contaminants. This ensures cleaner air and a healthier indoor environment.
After cleaning the ducts, we adjust the air flow rates to ensure that the air flow in your building is optimally distributed. This means that each room receives the right amount of fresh air, contributing to consistent air quality and ventilation system efficiency.
At AQ International, we also offer the service of air sealing ventilation ducts. By sealing the ducts, we ensure that no air escapes or enters the system uncontrolled. This increases energy efficiency, prevents imbalance in the system and ensures a safer and more reliable ventilation system.
With slightly older ventilation systems, little attention was paid to making ventilation systems airtight. Thus, you often have 30 to 40% of the air leaking and thus not getting to the right place. You can seal 90% of these leaks on average. As a result, you increase air quality and can reduce energy consumption.
After cleaning, adjusting and air sealing the ventilation ducts, we offer a comprehensive maintenance plan to ensure that your ventilation system continues to perform optimally. This includes periodic inspections and performing necessary maintenance to maintain the air quality and efficiency of the system over the long term.
Cleaning and balancing the ducts provides cleaner air and consistent air quality in all areas of the building.
By making the ducts airtight and optimizing the air flow rates, the ventilation system can save up to 30% energy.
Ventilation maintenance and cleaning reduces fire risk and ensures the safe operation of your ventilation system.
Proper ventilation system maintenance ensures that your system lasts longer, which lowers the cost of replacements and unforeseen breakdowns.
Our cleaning, balancing and air sealing services are ideal for a variety of industries, including:
In hospitals and residential care centers, it is essential to maintain healthy air quality. Our services help optimize air and increase energy efficiency.
Office complexes, shopping centers and other commercial establishments benefit from optimized ventilation and improved energy performance, increasing overall efficiency.
In industrial environments where ventilation ducts are heavily loaded, our service ensures that the system operates more efficiently and that airflow is optimal.
For hotels, comfort perception is crucial. A quiet, well-controlled and airtight ventilation system ensures a constant supply of fresh air without drafts or noise. At the same time, energy losses are reduced.
A healthy indoor environment is essential for the concentration and health of students and staff. Our approach helps to improve air quality, and meet legal standards around ventilation.
AQ International distinguishes itself by offering a complete package of ventilation duct cleaning, balancing and air sealing that maximizes the performance of your ventilation system.
We use advanced technologies and work to the highest safety standards to improve air quality and increase the energy efficiency of your system.
