Don’t Let Mould and Bacteria Circulate Through Your Home
Kleen Air offers professional air con cleaning services that keep your system running at peak efficiency and your indoor air fresh and healthy.
Improved Energy Efficiency
A clogged air conditioner has to work harder to cool your space, leading to higher power bills. A routine clean optimises airflow, ensuring your system runs more efficiently.
Deep Air Con Cleaning Service Kills Mould at The Source
Each time you turn on your AC, you could be spreading toxic mould, allergens, and chemical residues into every room. These pollutants can trigger:
- Asthma and allergies
- Chronic fatigue and sleep issues
- Sinus infections and sore throats
- Headaches, irritability, and poor air quality
Our deep air con cleaning service kills mould at the source, flushes bacterial growth, and removes the contamination other cleaners leave behind.
Clean air isn’t a luxury. It’s a necessity.
Specialised safe cleaning agents help kill bacteria and mould spores that can breed in damp conditions. We dismantle necessary components to thoroughly remove grime, mould, and debris. If we discover mould, we use
professional-grade treatments
to ensure a hygienic system.
Avoid Expensive Breakdowns With Preventative Cleaning
Avoid Expensive Breakdowns With Preventative Cleaning
Many homeowners assume cleaning or replacing the filter is enough. It’s not.
The most dangerous build-up is deeper: inside the coils, the fan barrel, and the drain tray.
That’s where moisture, grime, and mould mix to create a toxic environment that circulates through your entire home. Our technicians dismantle, clean, flush, and sanitise every critical part of your system. This isn’t a wipe-down — it’s a reset.
- Black mould
- Biofilm build-up
- Dust and allergens
- VOCs (volatile organic compounds) from cleaning products and chemicals
These aren’t just dirty — they’re dangerous. Kleen Air uses hospital-grade cleaning agents and specialised equipment to completely decontaminate your system from the inside out.
Why Clean Your Air Conditioner Regularly?
- Intense Summers
- High Humidity
- Energy Savings
- Year-Round Comfort
Temperatures in Brisbane can soar, especially from December through February. A well-maintained aircon is crucial for staying cool when you need it most. Moist air contributes to faster bacterial and mould growth. Frequent cleaning minimises these risks.
Clean systems run more efficiently, cutting down on power consumption and helping you save on electricity bills. Even outside of summer, a hygienic aircon ensures consistent airflow for heating or dehumidifying as needed.
What’s That Smell? You Might Be Breathing in More Than You Think
That musty, damp, or “old socks” smell coming from your air conditioner isn’t just unpleasant — it’s a warning sign.
Inside your system, the dark, moist environment is ideal for the growth of:
- Black mould and mildew
- Bacteria like Staphylococcus and E. coli
- Dust mites, pet dander, and pollen
- Volatile organic compounds (VOCs) from household products
- Stagnant water and biofilm build-up in the drain tray
Every time you switch on the air con, these contaminants are pushed through your vents and into your lungs. You might not see them, but you’ll feel them: fatigue, blocked sinuses, sore throat, dry eyes, recurring headaches — these are all signs of dirty indoor air.
If you or someone in your home has asthma, allergies, or a sensitive immune system, the risk is even higher. Children, the elderly, and people with respiratory conditions are especially vulnerable. And the worst part? It gets worse over time. That smell is your unit crying for help — and ignoring it could cost you more than just clean air.
Stop breathing contaminated air. Kleen Air removes the mould, flushes the bacteria, and restores your system to hygienic, powerful condition.

Call now to schedule a professional clean — before the problem spreads further.
FAQs for Kleen Air’s Air Con Cleaning
-
How do I know if my air conditioner needs cleaning?
If you notice musty smells, reduced airflow, or black spots around vents, it’s a clear sign your system is contaminated. Other red flags include increased power bills, noisy operation, and allergy symptoms indoors. If it’s been more than 6–12 months since your last clean, it’s time.
-
Can a dirty air conditioner really make me sick?
Yes. In Queensland’s climate, mould and bacteria thrive inside AC units. These contaminants can be blown into your home, triggering asthma, allergies, fatigue, and respiratory infections. Proper cleaning removes these hidden health hazards at the source.
-
How Often Should I Clean My Air Con?
We recommend a professional clean at least once a year, ideally before Brisbane’s peak summer season. If you notice musty smells or reduced airflow, book an extra service for peace of mind.
-
Can Regular Cleaning Reduce My Energy Bills?
Absolutely. A clean air con doesn’t struggle against dust or debris, using less energy to cool your space. This can lead to noticeable savings on your electricity bills, especially during high-demand months.
-
Do You Clean All Air Conditioner Types?
Yes! Whether it’s a split, ducted, multi-split, or cassette system, we have the skills and experience to handle it. Just let us know your unit type and any concerns when you book.
-
How Often Should You Clean Your Air Conditioner in QLD?
Our recommendation:
Every 6–12 months for homes
Every 3–6 months for rentals or businesses
Immediately if you notice: musty smells, poor airflow, high power bills, or mould
-
What’s included in a professional air con clean?
Our full hygiene service includes coil flushing, fan barrel sanitisation, drain tray cleaning, mould removal, and hospital-grade disinfection of all internal components. We go far beyond a basic filter rinse — this is a deep internal clean designed to restore performance and air quality.
-
Is air con cleaning different for split systems and ducted systems?
Yes. Split systems usually require direct internal cleaning, including coil and fan treatment. Ducted systems need more extensive hygiene across ducts, filters, and often multiple indoor heads. Our technicians are trained to handle both with tailored cleaning methods for maximum hygiene and safety.
-
Will cleaning my air conditioner lower my power bill?
Absolutely. A clean system runs more efficiently — meaning faster cooling with less power draw. Blocked coils and dirty filters force your unit to work harder, which spikes your energy use. Most clients see noticeable savings within their next bill cycle.
-
How long does an air con clean take?
Most residential split systems take around 45–60 minutes to fully clean. Ducted or commercial systems can take longer depending on size and condition. We provide fast, tidy service with minimal disruption — and you’ll notice the results immediately.
-
What’s that musty smell when I turn on the air con?
That smell isn’t “just dust.” It’s a mix of mould spores, stagnant water, and bacteria growing inside your unit. The odour means your system is contaminated — and what you smell, you’re breathing. Left unchecked, it only gets worse. If it smells off, it’s not clean.
-
Can my air con spread black mould through my house?
Yes. Mould thrives in the dark, damp parts of your air conditioner — and every time it runs, it can blow microscopic spores through your home. These spores latch onto walls, furniture, and lungs. It’s one of the most common — and dangerous — issues we find in Queensland homes.
-
Why does my air con make me feel tired or congested?
If your AC gives you headaches, itchy eyes, dry throat, or fatigue, that’s not normal — it’s a sign your indoor air is polluted. Dirty systems push volatile organic compounds (VOCs), mould fragments, and allergens into every room. Clean air shouldn’t make you sick.
-
Can dirty air conditioning trigger asthma or allergies?
Absolutely. Air conditioners full of dust mites, mould, pollen, and pet dander are a constant source of triggers. For anyone with asthma, allergies, or sensitivities, running a contaminated system is like breathing in the problem 24/7. We eliminate the source and restore safe airflow.
-
What kinds of bacteria are inside a dirty air conditioner?
Inside a neglected unit, we’ve found Staphylococcus, E. coli, and even Pseudomonas — bacteria that can cause skin infections, respiratory issues, and serious health risks. If moisture and dirt are present, bacteria will multiply. Our hospital-grade sanitation process removes them completely.
