We clean the full length of the return air ducts
We clean the registers and diffusers
We clean turning vanes and dampers
We clean VAV boxes and or mixing boxes
In a full system clean we clean all the components located in the air stream from the point the air enters the
system to the point the air exits the system.
Duct Cleaning using Negative Pressure Machine and Rotary Brush -After proper inspection and
planning, Negative Pressure Machine (NPM) is installed at one end of the air duct and from the other
end rotating brush is inserted into the duct. Rotating brush helps in loosening of the dust. Dust is
then sucked out by the NPM.
Cleaning using Air Whip -The technique is only used if solid dust or debris is stuck onto the walls of
Air Duct. Air Whip uses a vibrating and high-pressure air that breaks solid dust particles which gets
stuck to walls of air duct. High Air pressure helps in pushing them forward and is then sucked by
NPM.
Contact Vacuuming - Lastly contact vacuuming is done. It can reach places where brush cannot reach
and also at air duct joints where dust are stuck giving a completely Clean Air Duct. Also grills and
filters are cleaned used contact vacuuming.
Dust / debris disposal
Dust / debris disposal is done in a very careful manner. Removal of dust from NPM and other
machines is done in an appropriate way. It is either disposed off or given to client for chemical test.
Inspection after cleaning
Inspection after cleaning using RoboCam and IVS is done to verify whether any dust/debris is left over
and has not been removed. It also provides proof of cleaning and ensures that the job done has met
our high standards.
Clean Up
At the end of every day we will remove drop cloths, clean the entire work area and leave the premises cleaner
than it was when we arrived.
Reporting Phase
After the project is complete we will supply you with photo documentation that we have performed as
promised along with a Job Completion Certificate. If required we also provide with a VCD or SD CARD of the
video captured by our RoboCam.
Please note that the procedures mentioned above are a general guideline of how we perform every
project. Each job can vary depending on the building usage and working conditions and certain circumstances.
However our goal at every project always remains the same:
Work safely and neatly.
Don’t damage anything
Don’t release any forms of contamination into the building envelope.
Clean all the specified components according to NADCA Standards.
Visually inspect all work and verify cleanliness.
Take pictures / videos of all work to document cleaning effectiveness.
Submit documentation that we have performed as promised.
Guarantee all our work.
