Saudi Arabia's haboob dust storms and continuous sand-laden winds fill AC ductwork with particulate matter at rates 3–4× higher than Europe or North America. Dusty ducts redistribute allergens, bacteria, and fine particulates throughout every room every time the AC runs. For families with respiratory conditions, asthma, or allergies — and for any building that has been closed for several months — duct cleaning is one of the highest-value maintenance investments available.
What's Included
Negative air pressure machine creates vacuum in the duct system while rotary brush agitators loosen compacted dust deposits from duct walls. All dislodged material is captured in HEPA-filtered collection units — not released into the room.
Foaming coil cleaner applied to evaporator coil, allowed to dwell, and rinsed. Removes biofilm, mould spores, and dust that standard filter cleaning misses. The coil is the primary source of indoor air quality problems in ducted systems.
EPA-registered antimicrobial fogger applied to the internal duct surfaces and coil after cleaning. Eliminates bacteria, mould, and fungi present in the duct biofilm — remains effective for 3–6 months.
All supply and return grilles removed, cleaned in degreasing solution, and reinstalled. Visible grilles are the most obvious indicator of duct cleanliness — and the most frequently neglected.
Standard panel filters replaced. HEPA filter upgrades available — we size and retrofit HEPA filter housings into existing duct systems for allergy sufferers.
Before and after particulate count measurements (PM2.5 and PM10) using portable particle counter, with written report showing improvement achieved.

Frequently Asked Questions
How often should AC ducts be cleaned in Saudi Arabia?
In Saudi Arabia's dust-intensive environment, we recommend full duct cleaning every 2–3 years for permanently occupied homes, and before re-occupying a property that has been closed for 3+ months. After major construction or renovation (which generates enormous dust volumes), duct cleaning should be done before the system is run normally.
Can dirty ducts cause health problems?
Yes. Saudi ductwork collects desert dust (fine silica particles — PM2.5 and PM10 fractions), mould spores from condensate moisture on evaporator coils, and bacterial biofilm. In homes with members who have asthma, rhinitis, or dust allergies, contaminated ducts can significantly worsen symptoms. Even for healthy occupants, high airborne particle concentrations increase long-term respiratory health risk.
Is duct cleaning safe for my AC system?
When done correctly, yes — duct cleaning improves system efficiency by removing the insulating dust layer from coil surfaces (a 0.1mm dust layer reduces coil efficiency by up to 20%). However, aggressive cleaning with incorrect tools can dislodge flexible duct joints or damage coil fins. We use correctly sized brushes and controlled suction to avoid damage — always inspect before cleaning rather than applying maximum agitation.
How can I tell if my ducts need cleaning?
Visible signs: dust accumulation on supply grilles even immediately after cleaning, musty or stale smell from vents when AC starts, visible dark staining around vent diffusers. Technical signs: reduction in airflow from supply registers, increased filter loading frequency, occupant allergy symptoms worse when AC is running.
