Some Tips on Air Duct Cleaning

Not many of us give importance to the fact that the air passages that run all along the building are more prone to dust and debris accumulation than surfaces that lie open in a residence. Even though they are indirectly exposed to pollutions, they collect the entire stock from the air. The pile up after every duct cleaning session can be quite shocking with large amount of debris being recovered from the ventilation. Therefore, in any building with an air circulation system, duct cleaning procedure must be taken up more frequently. How is it possible to determine the right time to undertake cleaning of these ducts?

The best way to determine this would be to use few devices that detect pollution levels in the air that is released from the vents of the air ducts. One method is to use an olfactometer. This device indicates the extent of odor in the air. Presence of dirt and debris along with pests and termites in the air ducts will lead to change in the smell or odor of the air.
 
Once the smell is found to be different from normal standards, it is advised that you immediately ask for duct cleaning services. Here is a brief idea of what types of cleaners are used in a typical duct cleaning procedure.
 
Most cleaners use whips as the preliminary equipment attached to the end of the air compressor hose. The main function of this is to whip around wildly and loosen or break any accumulation of dirt in its path. The professional cleaner is only required to push these along the tube or duct and the whips adeptly whip around and break any debris build up. Thus, any accumulation of dirt in the tube will be partly or completely cleared by the whip.

Once the preliminary loosening of any build up in the duct is completed by the use of whips, the experts then use air hoses to suck out the debris that remains in the duct. The functioning of the hose is similar to a vacuum cleaner, as it is also attached to a power vacuum unit, which generates the desired suction pressure in the hose. This is the final tool that a professional cleaner will use to clear out the duct.
 
This was an account of the basic steps that are employed in duct cleaning. Minnesota residents need to keep these points in mind as they undertake professional help in cleaning of air ducts in their buildings.
