Duct cleaning & sanitising in Radwa

The filter catches dust before it enters the duct, but over the years fine particles slip through and stick to duct walls. If the filter is clean but the smell or allergy symptoms continue, the problem is likely deeper inside. A camera inspection shows the actual condition of the duct and settles the question.

Yes. The humid salty air from the sea enters through return-air openings carrying water vapour that condenses on the cool duct walls. This creates conditions where mould and bacteria grow, especially in sections far from the unit where airflow is weaker. Sanitising after cleaning inhibits that growth.

In most cases yes. We pass the camera and cleaning tools through existing grilles and access points. If a section is too long or narrow for the tools to reach, we may need to cut an access door, and we explain that at the inspection before starting; any opening cut is resealed when the work is done.

Most people notice the smell drops from the first run, and less dust settles on surfaces. Respiratory and allergy symptoms often ease gradually because the duct is no longer pushing irritant particles into the room. Airflow can also improve if deposits were partly blocking the cross-section.

Yes. If the camera shows that buildup is concentrated in a specific section, such as a duct near a return-air opening or an external passage, that section can be isolated and cleaned on its own. The inspector defines the logical work boundaries at the first visit so sections that need no work are not touched and sections that do are not missed.

It depends on the system size and how much buildup there is. We inspect by camera first to estimate time, then tell you how many hours roughly. Large villas typically take from a few hours to a full day.

Clean ducts reduce air resistance, allowing the motor to run more efficiently. But any saving on the bill depends on the central unit's age, filter condition and the building's thermal insulation.

We use safe and proven sanitising agents, and we seal off the areas during the process. After sanitising we flush the ducts again to remove any residue before restarting the system.

Yes, new ductwork can contain construction dust and coastal salt in the air even before heavy use. Camera inspection confirms whether cleaning is necessary.
