Grille & Diffuser Cleaning
The visible part of the system, restored properly rather than wiped over. It forms part of our wider AC duct cleaning offering, and can be booked as a standalone visit or combined with other work at the same property, which saves you a second call-out and earns a 10% discount on the additional service.
Ductwork is the one part of an air conditioning system nobody ever sees, which is precisely why it is the part that gets neglected. Over five to ten years, fine construction dust, textile fibers, pet dander, pollen and skin cells settle inside the ducts and form a compacted layer. In the humid months that layer holds moisture, and the result is microbial growth circulating through every room in the property.
What this service includes
- Removal, soak-washing and drying of all grilles
- Diffuser blade and damper cleaning
- Ceiling touch-up around grille frames
- Refitting with new gaskets where needed
Signs you need this service
- A stale or musty smell each time the system starts
- Allergy or respiratory symptoms that worsen indoors
- Dust settling on surfaces again within a day of cleaning
- The property has recently been through construction or fit-out works
Fixed written quotation issued before work begins. No hourly surprises, no charges added afterwards.

Our seven-stage method
Grille & Diffuser Cleaning follows the same documented process as every job in our AC duct cleaning division.
Survey and access planning
We inspect the duct layout, identify supply and return runs, count grilles and diffusers, and agree where access panels are needed. For apartments we confirm building rules and permits in advance.
Borescope inspection and evidence capture
A camera is inserted into the main runs and branch ducts, and the current condition is recorded. You see exactly what is inside your ductwork before we quote for cleaning it.
Containment and property protection
Furniture and floors are sheeted, the work area is contained, and the system is isolated so nothing that is disturbed inside the ducts can escape into the living space.
Mechanical agitation of the duct interior
Rotary brushes and compressed-air whips are run through the ductwork to release the compacted layer from the internal surfaces, working branch by branch back towards the collection point.
Negative-pressure extraction
A HEPA-filtered vacuum unit holds the duct system under negative pressure throughout, so every particle released by the brushes is drawn into the collection unit and removed from the property.
Grille washing and antimicrobial treatment
Grilles, diffusers and return filters are removed, washed, dried and refitted. The cleaned ductwork is then fogged with an approved antimicrobial treatment that is safe for occupied homes.
Post-clean inspection and report
The borescope goes back in and the same runs are filmed again. You receive before-and-after footage, a written report and a recommended interval for the next clean.

Grille & Diffuser Cleaning, questions and answers

Restoring free airflow usually improves system efficiency, because the blower no longer has to work against a restricted path. The saving varies by system and by how heavily fouled the ductwork was, so we prefer to show you the before-and-after footage rather than promise a percentage.
Yes, although flexible ducting requires a gentler technique to avoid damaging the inner liner. Where flexible runs are torn, crushed or beyond cleaning, we will tell you and quote for replacement instead.
