Professional Duct Cleaning Service in Dhaka
Dirty air ducts silently raise your electricity bills, spread dust and allergens, and strain your HVAC system. Mohammadi Engineering Ltd. clears every inch of your ductwork — so you breathe cleaner air and your AC runs the way it should.
What Is Duct Cleaning — And Why Does It Matter in Dhaka?
Air ducts are the hidden channels your HVAC system uses to distribute cool or warm air through every room. Over time they collect dust, pollen, mould spores, insect debris, and fine particles — and every time your system runs, it pushes all of that into the air your family breathes.
In a city like Dhaka, where dust levels are high and year-round humidity encourages mould growth, ductwork clogs far faster than in cooler climates. A blocked duct forces your HVAC system to work harder, shortens its lifespan, and drives up your electricity bill month after month.
Professional duct cleaning by Mohammadi Engineering Ltd. removes all built-up contaminants using industrial-grade vacuum equipment, rotary brushes, and safe disinfectant solutions — restoring proper airflow and improving indoor air quality immediately.
- Removes dust, mould, allergens, and bacteria from all duct surfaces
- Restores full airflow — your AC cools rooms faster and more evenly
- Reduces electricity consumption by 10–25% in heavily clogged systems
- Prevents mould and musty odours from spreading room to room
- Extends the service life of your HVAC unit and reduces repair calls
- Significantly improves conditions for asthma and allergy sufferers

Every Part of Your Duct System — Cleaned Properly
We don’t just clean the easy-to-reach vents. Our technicians disassemble, clean, sanitise, and reassemble every component for a genuinely thorough result.
Supply & Return Air Ducts
Full cleaning of all duct channels using high-powered rotary brushes and industrial vacuum extraction to remove years of dust and debris.
Air Registers & Grilles
We remove, deep-clean, and reinstall every grille so airflow is unobstructed. Visibly dusty registers are a sign the whole system needs attention.
Evaporator & Blower Coils
Dirty coils force your AC system to overwork. We clean coil surfaces and remove scale buildup to restore heat-exchange efficiency.
Air Handling Unit (AHU)
The AHU is the heart of any central system. We clean the blower wheel, housing, drain pan, and filter rack to prevent mould and improve performance.
Anti-Microbial Disinfection
After mechanical cleaning, we apply an eco-approved anti-microbial disinfectant throughout the duct system to eliminate mould spores, bacteria, and airborne pathogens.
Post-Cleaning Inspection
We test airflow from every vent and share findings with you. If we spot a duct leak or damage during the job, we tell you — no hidden surprises.
How We Clean Your Ducts — Step by Step
A structured, safe process that causes zero mess in your home or office and delivers a measurable improvement in air quality.
Site Assessment & Duct Mapping
Our technician inspects the full duct layout, identifies blockage points, checks for mould, and explains the plan before any work begins.
Area Protection & Equipment Setup
We cover furniture and flooring with protective sheets. Industrial vacuum hoses connect directly to the main duct trunk for contained extraction.
Mechanical Agitation & Vacuuming
Flexible rotary brush systems dislodge compacted dust from duct walls while high-suction vacuums extract all material — nothing escapes into your room.
Component Cleaning
Grilles, registers, the blower wheel, drain pan, and coil surfaces are individually cleaned. For HVAC systems, the AHU is serviced separately.
Anti-Microbial Treatment
A safe, eco-friendly disinfectant is fogged through the clean ductwork to neutralise mould, bacteria, and odour-causing micro-organisms. Child and pet safe when dry.
Final Check & Airflow Verification
We test airflow at each vent, reassemble all components, and run your system to confirm full performance is restored before we leave.
Does Your Ductwork Need Cleaning Right Now?
Most building owners wait until a breakdown before calling. These warning signs appear months earlier — don’t ignore them.
| Warning Sign | What It Means | Urgency |
|---|---|---|
| 💨 Weak airflow from vents | Significant dust/debris blockage — your fan is working harder for less output | High |
| 🤧 Increased allergy or asthma symptoms | Mould spores or allergens circulating through dirty ductwork into every room | High |
| 😷 Musty smell when AC runs | Mould or bacterial growth inside the duct or on the drain pan | High |
| 💸 Rising electricity bill (no usage change) | Restricted airflow forces the compressor to run longer to reach set temperature | Medium-High |
| 🌫️ Visible dust puffs from vents on startup | Heavy buildup being pushed out — clear sign the system is overdue for service | Medium-High |
| 🕐 AC takes longer to cool the room | Reduced airflow limits heat exchange — connected to both duct and AC health | Medium |
| 📅 No cleaning done in 2+ years | Preventive action — 1–2 year cleaning cycles recommended in Dhaka conditions | Preventive |
| 🏗️ Recent renovation or nearby construction | Construction dust is extremely fine and penetrates ductwork quickly | Medium-High |
