Dirty air ducts are also dangerous in terms of fire safety. There are cases when even a small spark or grease, falling into the duct for kitchen hoods, caused a fire that spread at lightning speed throughout the room. Therefore, it is very important to regularly use the services of air duct cleaning near me. 

Causes of duct pollution

During the operation of  the air , inside it, or rather on its inner surface, dirt, soot, dust and other harmful deposits settle in large quantities. In addition to these factors, small debris, for example, that appeared after any repair work, can become the cause of air duct contamination.

What are the dangers of clogged air ducts?

First of all, the fact that dirt tends to clog the duct channels, often narrowing its diameter, and in some cases completely blocking it. This state of affairs leads to an additional load on the ventilation equipment, and as a result, to their premature failure.

In addition to polluting the air duct and degrading the performance of ventilation equipment, clogging is very detrimental to the quality of the air itself, and in addition, dirty chimneys become both a source and a breeding ground for pathogens, microorganisms, mold, and even insects and small rodents.

Duct cleaning

To prevent the development of negative phenomena associated with clogging of the air duct, it is recommended to periodically clean the air duct system. Timely cleaning of the ventilation system will reduce the unnecessary load on the ventilation equipment, and at the same time improve the quality of the air that enters the room through this system. Not so long ago, only their complete replacement was considered the main way to get rid of clogged air ducts, but today this situation has changed dramatically, as tools and devices have appeared that allow organizing effective cleaning of even very dirty air ducts and ventilation ducts.

At the moment, air duct cleaning includes several important steps:

1. Evaluation of the general state of canal clogging. At this stage, a visual inspection is organized using special equipment, which is often represented by robotic machines equipped with a searchlight and a video camera, which, when moving along the duct, can display a visual image on the monitor screen. In addition to visual inspection, samples are also taken for various tests for the presence of pathogens. Based on the assessment of visual inspection and analysis, a conclusion is made about the feasibility of cleaning the duct.

1. Direct cleaning of the air duct. It is highly recommended to close all openings and valves of the air distribution system before starting cleaning work. Then a vacuum machine is connected to one of the sides of the duct, which is necessary to organize a negative pressure of high potential. The equipment has a highly efficient filter system and a powerful electric motor to ensure high cleaning efficiency even in harsh conditions. A special machine with brushes is connected to the second outlet of the air duct, which is capable of cleaning both round and rectangular air ducts. The composition of this equipment includes, as a rule, a rigid case made of durable metal, controls, a flexible shaft, a set of brushes that can rotate in several directions,

Due to the pressure that the vacuum machine creates, deposits, dirt and debris are removed from the air duct, immediately entering special filters at its outlet. This method is effective for air ducts with a diameter of 0.15 to one meter. If the cross section of the duct is relatively small, then good cleaning results can be obtained by using a special brush connected to an electric motor.

In cleaning the air ducts of ventilation equipment, which works in catering places (restaurants, canteens), the "dry ice" cleaning method has proven itself well. The principle of this method is to bombard the inner surface  of the air with dry ice particles for ventilation . As a result of this action, both simple and difficult-to-remove fat deposits are "undermined", which, when loosened, can be easily removed using a vacuum machine. Compared to chemical duct cleaners, dry ice is environmentally friendly and provides guaranteed results.
