When assembling a ventilation or chimney system, special attention is paid to tightness, since the efficiency of the air ducts depends on this parameter. It is important that the channels not only do not let in exhaust air with unpleasant odors and combustion products but also do not impede the movement of air masses. Problems with drafts usually arise when the air ducts are clogged.

The fact is that particles of fat, soot carbon, dust, and other waste settle on the walls of the channels. In the future, the process will accelerate exponentially. As a result, the channel cross-section narrows. In addition, the surface becomes rough, and therefore the draft is difficult. This is especially noticeable when using natural rather than forced draft. In this regard, the cleaning periods for ventilation chambers and air ducts are strictly regulated by regulatory documents and the legislative framework.
What does the law say?
Article 50 of the Fire Safety Rules of the American Federation states that the head of the organization is obliged to determine the procedure for cleaning air ducts and ventilation channels, as well as replacing filters, cyclones, and other elements responsible for removing flammable products. Air ducts must be cleaned at least once a year with the preparation of a corresponding act. Although the timing depends on the operating conditions and external factors. For example, ventilation systems that remove air from professional stoves must be cleaned once every 1-2 months. Chimneys must be cleaned before the start of the heating season.
The need and frequency of work are regulated by fire safety regulations since the risk of fire increases if soot and grease are not removed promptly. In the event of an accidental fire (a spark may come from a stove or range), the fire can quickly spread throughout the entire system, especially under forced draft.

The frequency of cleaning air ducts from flammable waste may also depend on the materials from which they are made. For example, if the ventilation in an underground parking lot or other place is made of Air Duct Vet polymer material, cleaning, and preventive maintenance can be done once a year. The fact is that after the polymerization process, flexible pipes become hard and smooth inside. The absence of porosity and roughness does not contribute to the adhesion of particles of fat, soot, and other flammable waste to the walls. In this regard, regular work should be done less often, and the cleaning process itself is usually quick.
Who cleans air ducts?
The responsibility for timely cleaning of ventilation ducts and chimneys lies with the head of the organization. He usually entrusts the work to the operation service, which employs experienced specialists with the necessary experience and qualifications. It is strictly forbidden to carry out cleaning independently without the appropriate education. The act of work performed serves as a certain proof of the qualifications of employees. Usually, company owners conclude a long-term cooperation agreement, although they can also hire workers one time, observing the frequency of cleaning of ventilation ducts and air ducts.
