Grille cleaning is not duct cleaning
Removing and washing the return grille and supply diffusers is useful and quick. It is part of a standard deep clean. It is not duct cleaning and should not be priced as such.

ServicesWhat AC Duct Cleaning Involves, and What It Does Not
This is the service with the widest gap in the UAE between what is quoted and what is delivered, because almost none of the work is visible once the grille goes back on.
What the real job needs
Mechanical agitation along the duct run — rotary brushing or compressed-air whipping — with a HEPA-filtered negative-pressure unit collecting what is dislodged. Without the collection unit, debris is pushed further in or out into the room.
The parts usually excluded
The evaporator coil and the blower wheel. These are frequently the actual cause of poor airflow and odour, and they are frequently left out of the quote. Ask in writing.
Evidence to require
Before and after footage from inside the duct, not photographs of a grille. Any contractor with a duct camera can supply it. One without a camera cannot clean the run properly either.
Everything we do is scoped against luxury deep cleaning, priced after an inspection and fixed in writing before any work begins.
Questions
Answered plainly.
It depends on the building and the filter regime rather than a fixed interval. Ceiling staining, odour on start-up, and running the system through a fit-out are the three clear triggers.
Only if the ducts are the restriction. Often it is the coil or blower wheel instead, and a good contractor diagnoses before quoting.
After mechanical cleaning, as a finishing step. Fogging a dirty duct perfumes it.
Questions this did not answer? Just ask.
An inspection, a written scope and a price that holds. We will also tell you when the job does not need us.
