A ducted heating and cooling system moves air through metres of ductwork that slowly fills with dust, allergens and sometimes mould. A professional clean clears it out so your air is healthier and your system runs more efficiently.

Our technicians clean the vents, ductwork and filters, check the system, and treat any mould, across Brisbane, Perth and Adelaide.

Why clean your ducted system?

Your ducted heating and cooling system circulates air through every room of your home, so when the ducts, filters and components are dirty, that dust, mould and debris gets blown into the air you breathe. Cleaning your ducted system improves air quality, restores airflow and efficiency so it runs cheaper, removes musty smells, and helps the system last longer. A neglected ducted system works harder, costs more to run, and can aggravate allergies and asthma. Regular cleaning and servicing keeps the air fresh, the system efficient, and your running costs down. We clean and service ducted systems across Brisbane, Perth and Adelaide.

Signs your ducted system needs cleaning

Your ducted system will often show when it is due for a clean:

Musty or stale smells when it runs
Weak airflow from the vents
Dust visibly blowing from vents, or settling fast after cleaning
Rising power bills as it works harder
Allergy or asthma symptoms worsening indoors
Visible dust or mould around the vents or return air grille
The system struggling to heat or cool

If you notice these, your ducts, filters or components are likely dirty and a clean and service will restore performance and air quality.

What is involved in cleaning a ducted system

Cleaning a ducted system is more than wiping the vents. A thorough clean and service covers the return air filter, which traps dust before it reaches the system; the vents and grilles in each room; the indoor fan coil unit and its coils; and the ductwork itself where accessible. We also check and clean the outdoor unit and inspect the system operation. Cleaning restores proper airflow, removes the dust and mould that affect air quality, and improves efficiency. Because a ducted system has many components spread through the roof space, a proper clean and service is best done by professionals with the right equipment, which is what we provide.

Air quality and your health

The air your ducted system circulates goes straight into your lungs, in every room, so a clean system matters for health. When filters, coils and ducts are left dirty and damp, dust, mould, bacteria and allergens build up and get blown throughout the home, which can trigger allergies, asthma and that musty smell when the system starts. This is especially important for households with children, older people, or anyone with respiratory conditions. Because a ducted system distributes air everywhere, a dirty one affects the whole house, not just one room. A proper clean removes the build-up, so the air circulating through your home is clean and fresh.

Cleaning the return air filter

The return air filter is the most important part of a ducted system to keep clean, because it traps dust before it reaches the system and gets blown back out through the vents. As it clogs, airflow drops, the system works harder and costs more to run, and dust starts bypassing it. The large return air grille is usually in a central hallway or ceiling. This filter needs regular cleaning, more often than many people realise, and should be part of your routine maintenance. We clean or replace the return air filter as part of a service, and can show you how to keep it clean between visits, which makes a big difference to airflow and air quality.

Mould in ducted systems

Ducted systems can develop mould, particularly in the cooling coils and anywhere condensation collects and stays damp, and once mould is present it gets circulated through the home as musty-smelling, allergen-laden air. Mould is a health concern, especially for anyone with allergies or asthma, and that persistent musty smell when the system runs is a common sign of it. Cleaning the affected components, the coils, drain and relevant parts, removes the mould and the smell. Keeping the system clean, the drain clear and the filter maintained helps prevent it returning. We clean mould-affected ducted components so your system blows fresh, clean air rather than spreading spores and odours.

Improving efficiency and cutting bills

A dirty ducted system is an expensive one. As filters and coils clog with dust, airflow drops and the system has to run harder and longer to reach the set temperature, using more energy for less comfort, which shows up on your power bill. Dirty coils also insulate the system from the air it is trying to condition, reducing efficiency further. Cleaning restores airflow and heat transfer, so the system does its job with less energy. Across a whole home and a full heating and cooling season, that efficiency gain adds up to real savings. Regular cleaning is one of the simplest ways to keep your ducted running costs down.

How often should you clean a ducted system?

As a general rule, a ducted heating and cooling system should be serviced and cleaned once a year, ideally before the peak heating or cooling season, so it is ready when you need it. The return air filter needs cleaning more often than that, depending on use and how dusty your home is, often every few months. Homes with pets, in dusty or renovated areas, or where the system runs most of the year, benefit from more frequent attention. Regular yearly cleaning keeps the air fresh, the system efficient and problems caught early. We can set you up with a maintenance schedule that keeps your ducted system in top condition.

Cleaning vs a full service

Cleaning and servicing go hand in hand for a ducted system. A clean focuses on removing dust, mould and debris from the filter, vents, coils and ducts to restore airflow and air quality. A service goes further, checking the refrigerant, electrical connections, controls, drain, fan and overall operation, and catching developing faults. For a ducted system, the two are usually best done together, so the system is both clean and mechanically sound. We provide a complete clean and service, so your ducted system blows clean, fresh air and runs efficiently and reliably, rather than just looking clean at the vents.

Ducted system drain and condensation

As a ducted system cools, it removes moisture from the air, and that condensation drains away through a condensate drain. If this drain blocks with dirt, mould or slime, the water can overflow, causing damp, leaks and the mould that breeds in standing water, which then affects the air quality. Clearing and flushing the condensate drain is part of a proper clean and service, preventing leaks and keeping the damp conditions that grow mould under control. A blocked drain is a common cause of water problems and musty smells in ducted systems, so we check and clear it as standard to keep your system clean and dry.

Commercial ducted cleaning

Ducted systems in offices, shops and other commercial premises circulate air to staff and customers all day, so keeping them clean matters for health, comfort and the impression your space gives. A dirty commercial system spreads dust and can breach the air-quality expectations of a workplace, as well as costing more to run. We clean and service commercial ducted heating and cooling systems, and can work around your trading hours to minimise disruption. Regular cleaning keeps your system efficient, your air fresh, and your running costs controlled, and helps avoid the breakdowns that a neglected system eventually suffers. We can set up a maintenance schedule to suit your premises.

How much does ducted cleaning cost?

The cost of cleaning a ducted system depends on the size of the system, the number of vents and zones, its condition, and whether it is a routine clean or a deeper clean of a heavily neglected or mould-affected system. A system that has not been cleaned in years takes more work the first time. Combining the clean with a full service is usually the most economical approach, since both are done in one visit. We assess your system and give you an upfront fixed price before we start, so you know the cost, with no surprises. Regular cleaning costs far less than the running-cost waste and repairs a neglected system brings.

Keep your warranty and system healthy

Regular cleaning and servicing not only keeps your ducted system efficient and the air clean, it also helps maintain the manufacturer warranty, which usually requires the system to be serviced by a qualified technician. Skipping maintenance can void the warranty, leaving you to pay for a repair that should have been covered, and a neglected system fails sooner. Looking after your ducted system protects a significant investment and keeps it delivering comfortable, efficient whole-home conditioning for many years. We service to manufacturer requirements and keep records, giving you the documentation to support any future warranty claim, as well as a clean, healthy system.

Ducted cleaning FAQs

How often should ducted air conditioning be cleaned?

Every few years for most homes, or sooner if you have allergies, pets, nearby renovations, or notice dust and musty smells from the vents.

How much does ducted cleaning cost?

It depends on the number and length of ducts, access and build-up. We assess your system and give you an upfront fixed price.

Does duct cleaning improve air quality?

Yes. Removing built-up dust, allergens and any mould from the ducts means cleaner air circulating through your home.

Can duct cleaning lower running costs?

A cleaner system moves air more freely and runs more efficiently, which can help reduce running costs.

What is included in a ducted clean?

We clean the vents and ductwork, clean or replace the return filter, check the indoor unit, and sanitise where mould or odours are present.

What is the difference between ducted cleaning and a service?

Cleaning focuses on the ducts and air quality; a service checks and maintains the whole system. We offer both and can combine them.

Do I need ducted cleaning if I have no symptoms?

Not always. It is most worthwhile when you have allergies, visible dust, musty smells, or the system is running poorly.

Do you offer same-day service?

In many cases, yes. We service and clean ducted systems across Brisbane, Perth and Adelaide.
