Frequently asked questions

Source removal means physically loosening contaminants from inside the ducts and extracting them under negative pressure. It is the method recognised across the duct cleaning industry as effective. Fogging or spraying products into vents without mechanical cleaning may mask odours but leaves the dust and debris in place, so we always clean mechanically first.

It can if the wrong tools are used. Flexible ducts have a thin inner liner that aggressive brushes can tear. We use softer brush heads or air whips on flexible runs and reserve stiffer tools for sheet-metal trunks. If the camera shows existing damage, we photograph it and let you know.

Looking through a vent opening only shows the first few centimetres. A camera shows conditions deeper in the duct, including debris levels, disconnections and moisture marks. Inspecting before and after cleaning gives you a clear comparison and helps us confirm each branch has been properly cleaned.

Yes. We provide before-and-after photos and brief notes on the condition of the system. Landlords and property managers often find this useful for maintenance records or when discussing the system with tenants. Let us know when booking if you need the information sent to someone other than the occupant.

Cleaning only part of a system leaves contaminated sections that can redistribute debris into the clean areas once the air con runs again. We generally recommend cleaning the full system in sequence. If inspection shows certain branches are genuinely clean, we will note that and adjust the scope.

It depends on the number of outlets, the length of runs and how easy roof access is. A compact apartment system may take a few hours, while a larger house with long runs can take most of a day. We give you an estimate with the quote so you can plan around the visit.

Someone needs to let us in and should ideally be available at the end, when we walk through the findings and camera footage. In between, you are welcome to go about your day. For rentals, a property manager can arrange access if the tenant agrees.

If the filter is worn, torn or heavily loaded, replacement is sensible, because a tired filter lets dust straight back into freshly cleaned ducts. Washable filters in good condition can be cleaned and refitted. We check the filter during every job and tell you which option suits your system.

Clear a path to the return grille and any manhole used for roof access, and move fragile items away from outlets where possible. Let us know about pets, alarm systems or parking restrictions. We bring drop sheets and protect the areas we work in.

A heavily blocked filter, plenum or duct makes the system work harder to move air. Clearing that build-up can help it run closer to its design airflow. The effect varies from system to system, so we will not promise particular savings, but restoring airflow is part of the reason to clean.

Yes. Apartment systems are usually smaller but can be harder to access, with the indoor unit and ducts hidden above bulkheads or in cupboards. We check building rules on contractor access, lift use and parking in advance and contain all equipment within the apartment while we work.
