A proper maintenance of the HVAC system represents a key step in the process of improving the quality of indoor air. In fact, by neglecting this step, the contaminants that accumulate in the latter, are released back into the ambient air, thus contributing to the pollution of the indoor air.
The main purpose of cleaning air ducts of HVAC systems is to remove the contaminants (dust, debris, mold, mildew, and other) so that air can circulate on surfaces clean and restore the efficiency and effectiveness of systems, C. V. A. C.
We have the certification VSMR (Ventilation System Mold Remediator) issued by NADCA, to proceed with the cleanup of your HVAC system contaminated.
We use the principle of suction, friction, impulse in our cleaning process.
THE TWO METHODS THAT WE USE FOR OUR CLEANING PROJECTS ARE :

The value of the robots is invaluable when it comes to access to areas difficult to access. The robot can anticipate and circumvent an obstacle to the need. Electric power tools and pneumatic tools each have their own source of energy, respectively, electricity and compressed air. Both contain rotating brushes to remove debris from the surface of the ducts. These are subsequently routed to the dust collector to negative air where they are vacuumed. The spraying devices are used to spray disinfectants and coatings. Airless sprayers are commonly used for this task. The solutions can be sprayed by a technician from a service point or by a carriage spray or a robot.

In many cases we associate the "duct cleaning" in the "indoor air pollution". In fact, the cleaning of the ventilation ducts is increasingly prevalent due to the growing concerns over the pollution of the indoor air. Although the majority of the problems of indoor air quality can be related to conditions not related to the system of air circulation, some problems are directly related, at least in part. The majority of the problems of indoor air quality (IAQ) are from a variety of factors such as the good state of the system of heating, ventilation, and air conditioning (HVAC) equipment.
The main purpose of cleaning air ducts of HVAC systems is to remove visible contaminants such as dust, debris and moisture of the entire system of ventilation so that air can circulate on clean surfaces. Microbial contaminants such as yeasts and fungi, which may be invisible to the naked eye, can also be removed from the HVAC system with the proper cleaning and sanitizing procedures. The presence of microbial contaminants in an HVAC system is not exceptional. However, the presence of active microbial growth is of concern, since they can affect the quality of indoor air and cause health problems in some people.
The many benefits of duct cleaning include, among others, a reduction in the risk of indoor air pollution, complaints from occupants about their health or their comfort and possibly a reduction in energy costs by allowing the mechanical components to operate more efficiently and have a better life.
The industry of the cleaning of the ventilation ducts is not regulated. In 1989, a group of entrepreneurs working in the field of cleaning of the ventilation ducts and equipment manufacturers formed the National Air Duct Cleaners Association (NADCA). Since its inception, NADCA has established industry standards for its members, as well as a certification program Air Systems Cleaning Specialist (ASCS) that includes continuous training and internships. In addition to having developed the standards of cleaning, NADCA has worked with the Agency for the protection of the environment (APE), to measure the effectiveness of the cleaning of the ventilation ducts, at the suggestion of the EPA to require providers of services of cleaning of the ventilation ducts to meet the standards NADCA.
Cleaning of ventilation ducts have exceeded the principle of "eliminate, at the source", that is to say, remove visible contaminants within the system. The vacuum systems are essential for duct cleaning. Any vacuum cleaner that returns the air to the interior of the building must contain a HEPA filter that can trap a 99.97% of particles larger than 0.3 microns. The process consists of connecting a large vacuum HEPA filter in the system of ventilation ducts or any part of it, in order to create a negative pressure which will not let any contaminants.
It is enough to consider the large number of devices used these days for the cleaning of the ventilation ducts to be aware of the technological advances of the last ten years.
The devices used for inspection are used to examine the inside of the air conditioner or the presence of debris, contaminants in the ductwork and to check their condition. The endoscope is a device used to perform a direct viewing. The endoscope is inserted into an existing opening or created, such as a ventilation opening, which allows you to place the endoscope in the region to be examined. Endoscopes are usually equipped with a lighting system of 115 watts, an angle of view of 40 degrees and can be equipped with small cameras, 35mm and digital, which broadcast the image on a screen.
Flexible endoscopes (optic; optical fiber) and the video work the same way as endoscopes, but have the advantage of being more malleable and can easily get around the obstacles in the ventilation ducts. A system of closed-circuit television is used to drive the device in the ear. A system video recorder with sound and image can also be installed. This device controlled remotely can be run in ducts and offers all the same benefits as other devices. The equipment robot are available in several shapes and sizes. With their caterpillars, they look like toys of tanks. The robots can be equipped with two cameras, one at the front to guide her back into the ducts and the other at the back to guide her to leave. They can also be used for cleaning, spray and sample.
There are two types of systems, industrial vacuum cleaner: the ones with HEPA filters, high efficiency particulate air (the air passes through a filter in a space occupied), and filters that are non-HEPA (the air in a space when unoccupied, usually to the outside of a building). A vacuum cleaner equipped with a HEPA filter are very effective and are used in clean room facilities (factories) and the operating rooms of hospitals. They filter a 99.97% of particles of 0.3 microns or more, or about one-hundredth the size of a pen tip. Large vacuum equipped with a HEPA filter, called sensor negative air, or negative air machines are used to create a negative pressure in one part of the system. This ensures that dust or debris will be sucked in and could not enter the occupied space. The dust collectors negative air contain a filtration system in stages, of which the latter includes the HEPA filter. Portable vacuum cleaners with HEPA filter, which look and operate similar to the Shop-Vac are used for manual vacuum aspiration, or direct contact, the air conditioners or the ductwork. There are also vacuums industrial liquids equipped with a HEPA filter to remove the contaminated water that can be found in the recycling bins, and in the ducts flooded.
Vacuum cleaners equipped with a filter non-HEPA are commonly used to create a negative pressure and remove debris. The static pressure is deployed is a great strength because the particles are only slightly filtered. They are, therefore, placed on the outside of the occupied spaces, usually to the outside of the building. Their mode of use in the cleaning process is the same as that of vacuum cleaners with a HEPA filter. They can also be used to pick up larger debris such as pieces of insulation.
The equipment robotic remote-controlled to provide all benefits listed above plus the ability to accommodate a variety of accessories such as rotating brushes, air nozzles or air whips, devices to collect samples, spray systems for the disinfection products, or different coatings. The value of the robots is invaluable when it comes to access to areas difficult to access. The robot can anticipate and circumvent an obstacle to the need. Electric power tools and pneumatic tools each have their own source of energy, respectively, electricity and compressed air. Both contain rotating brushes to remove debris from the surface of the ducts. The debris is subsequently routed to the dust to negative air where they are removed manually. A cleaning apparatus is equipped with an electric toothbrush at the end of the suction hose to a HEPA filter. The debris are sucked up as they come off the walls. Pneumatic tools are used blowguns, air, directional nozzles-to-air and air whips to shake, loosen and push the debris into the dust sensor air negative (with compressed air). (It is called the technique of the push-pull).
The spraying devices are used to spray disinfectants and coatings. Airless sprayers are commonly used for this task. The solutions can be sprayed by a technician from a service point or by a carriage spray or a robot. A closed-circuit television, and a video camera can be fixed to the trolley spray devices or of spray can be attached directly to the robot.
