Professional Duct Cleaning Service in Dhaka
Dhaka’s dust, humidity, and pollution fill your AC ducts with mold, allergens, and debris over time. We clean them thoroughly so your indoor air stays fresh and your AC runs efficiently.
Dirty Ducts Cost You More Than You Think
Most Dhaka homes and offices never get their ducts cleaned. Here is what happens when dust, mold, and grime build up inside your AC ventilation system year after year.
AC Runs Longer, Cools Less
Clogged ducts force your AC to work 30-40% harder. That means higher electricity bills every month without getting better cooling.
Allergies and Breathing Issues
Mold spores, dust mites, and pet dander collect inside ducts and blow into every room every time the AC turns on.
Foul Odor from Vents
That musty smell coming from your AC? It is likely mold growing inside the ductwork. Cleaning eliminates the source, not just the symptom.
Shorter AC Lifespan
Dust-covered ducts strain the blower motor and compressor. Regular cleaning extends your AC system life by years.
6 Signs Your Ducts Need Cleaning Right Now
Do not wait for a complete system failure. If you notice any of these, schedule a duct inspection today.
Dust on Vents and Surfaces
If you wipe dust off your supply vents and it comes back within days, your ducts are circulating contaminated air.
Musty Smell When AC Runs
Persistent damp or earthy odor from vents points to mold or mildew growth inside the ductwork.
Uneven Cooling Across Rooms
Some rooms stay warm while others freeze? Blocked or dirty ducts restrict proper airflow distribution.
Rising Electricity Bills
When your AC struggles to push air through dirty ducts, it consumes significantly more power.
Frequent Allergy Symptoms
Sneezing, coughing, or watery eyes that get worse indoors? Your ducts might be the hidden culprit.
Visible Mold Near Vents
Black or dark spots around duct openings or on ceiling tiles near vents mean mold has already spread inside.
Our 5-Step Duct Cleaning Process
We follow a systematic approach that cleans every inch of your ductwork without damaging the system. No shortcuts, no surface-level wiping.
Ductwork Inspection
Our technician inspects all accessible duct sections using a camera probe to identify blockages, mold patches, and damage points before starting.
Supply and Return Register Removal
We remove all vent covers and registers, clean them separately, and seal off openings to prevent dust from escaping into your rooms.
High-Powered Vacuum Cleaning
A truck-mounted or portable HEPA vacuum system pulls loose debris, dust, and contaminants out of the entire duct length.
Mechanical Agitation and Brushing
Rotary brushes and compressed air tools dislodge stubborn grime, mold, and stuck-on deposits from duct walls.
Sanitization and Final Check
We apply an EPA-approved antimicrobial treatment, reattach all registers, run a post-cleaning airflow test, and walk you through the results.

Why Duct Cleaning Is Different in Dhaka
Dhaka has its own set of problems that make duct cleaning not optional but necessary. The air quality index frequently crosses unhealthy levels. Add to that the constant construction happening in almost every neighborhood — Mirpur, Uttara, Banasree, Badda — and you have a continuous supply of fine dust particles entering your AC system.
Then there is the humidity. Dhaka’s monsoon season pushes moisture levels above 80% for months. That moisture sits inside dark, warm ductwork and creates the perfect breeding ground for mold and bacteria. By the time you notice a smell, the colony has already spread through meters of ducting.
We also see a lot of cases where previous AC repair work left debris inside the duct — insulation fragments, screws, and tape residue. Our initial inspection catches these issues so they can be addressed during the cleaning process itself.
If you have recently had AC installation done or moved into a new apartment, getting the ducts cleaned should be one of your first priorities. You have no idea what the previous occupant let accumulate in there over the years.
Duct cleaning also pairs well with a full AC cleaning service. When you clean the indoor unit, the filters, and the ducts together, the improvement in air quality is immediately noticeable. Many of our clients in Dhanmondi and Gulshan book both services together for a complete solution.
