Free site audit & transparent linear-foot estimate
NADCA Certified Methodology
Our 6-Step Certified Duct Cleaning Process
We never perform superficial vent wipe-downs. Our team conducts end-to-end negative pressure evacuation and rotary mechanical scrubbing.
Borescopic Video Inspection
Our engineers insert high-definition robotic snake cameras into the main supply and return trunks to locate dust dams, mold colonies, and dead rodents.
Negative Air Machine Hookup
We seal all registers and connect a 2,500+ CFM industrial HEPA negative pressure machine, ensuring no dust or contaminants escape into your living or office space.
Mechanical Rotary Brush Agitation
Motorized flexible shaft rotary brushes sweep through the duct interior, scrubbing stubborn hardened grime, caked soot, and fungal mycelium off metal walls.
Compressed Air Whip Extraction
High-pressure pneumatic air whips blast into inaccessible duct corners, driving all dislodged particulates straight into the high-vacuum filtration collection unit.
EPA-Approved Anti-Microbial Fogging
We disperse an ultra-low volume (ULV) germicidal botanical aerosol through the entire duct network to neutralize odor-causing bacteria, virus particles, and mold spores.
Airflow CFM & IAQ Quality Certification
We measure post-cleaning airflow velocity with digital anemometers and provide a comprehensive Before/After photo inspection report for your records.

Why Dirty Air Ducts in Dhaka
Silently Poison Your Office & Home
Dhaka's heavy construction dust and vehicle fumes combine with monsoon relative humidity of over 85%. When conditioned air cycles through uncleaned ducts, dark and damp conditions promote the explosive growth of Stachybotrys (toxic black mold) and bacterial biofilms.
Employees experience frequent headaches, morning sinus congestion, and chronic coughs (Sick Building Syndrome). Furthermore, just 1mm of dust on internal duct evaporator coils increases compressor energy draw by 21%, costing thousands of extra Taka in monthly electricity bills.
