Dirty ACs Can Increase Mould Spores 137x

Your AC is a breeding ground when not maintained.

Mould in air conditioners can release spores and allergens into the air you breathe. Scientific evidence links indoor mould exposure to increased risks of respiratory symptoms, allergies, asthma attacks, and other health issues. Dirty or poorly maintained AC units create ideal moist conditions for mould growth, potentially circulating harmful fungi throughout your home.

Reasons to deep clean your split system air conditioner.

Regular professional cleaning of your split system air conditioner delivers far more than a fresh smell — it protects your health, reduces running costs, and extends the life of your unit. Here are the key benefits:

1. Improved Energy Efficiency
   A clean system will use less electricity to cool or heat your home. If there is dust, mould or debris, the system will use more power and drive up electricity bills.  Deep cleaning restores proper airflow and can noticeably lower your energy usage.
   
2. Better Health and Indoor Air Quality
   Mould, bacteria and allergens trapped inside dirty air conditioners are continuously circulated throughout your living spaces. Removing this buildup is especially important for households with asthma, allergies or respiratory sensitivities, delivering cleaner, healthier air for your family.
   
3. Elimination of Unpleasant Odours
   That musty or “funky” smell coming from your vents is usually a clear sign of mould or bacterial growth. Visible black spots inside the unit confirm the problem – though mould and bacteria will also grow behind the grills which can’t be seen. A thorough deep clean removes the source so you can enjoy fresh, odour-free air.
   
4. Prevention of Water Leaks
   Blocked coils and drain lines cause condensation to back up, leading to leaks, water damage and potential overflow. Keeping these components clear ensures proper drainage and helps protect your ceilings and walls from costly moisture issues.
   
5. Extended Lifespan of Your Unit
   When an air conditioner is clogged with dirt and mould, it works harder, straining to maintain temperature. Regular deep cleaning reduces stress on the components, helping your system last significantly longer and delaying the need for expensive repairs or replacement.

Before & after

Professor Clean Air is more than a quick wipe-down.

Professor Clean Air was founded by Bailey, a fully qualified refrigeration technician (fridgey) with over 10 years of hands-on experience in air conditioning installation, repair and maintenance.

Bailey started this business after hearing the same complaint too many times: customers who had paid hundreds of dollars for air conditioner cleaning, only to discover mould still growing inside their units weeks later. They’d paid big dollars for a quick, superficial wipe over, leaving behind hidden mould, bacteria and debris.

Its done differently at Professor Clean Air.

We specialise in proper deep cleaning of split system air conditioners, getting in behind the grills to remove hidden mould, bacteria, dirt and debris. Our entire process is built around one clear goal: removing mould, bacteria, and built-up contaminants so the air circulating in your home is genuinely clean and healthy. We take the extra time to do the job thoroughly — never cutting corners — so your system runs more efficiently, quietly, and reliably.

As a locally owned, family business, we pride ourselves on friendly, reliable service and real attention to detail. When you call us, you’re dealing directly with people who care about the outcome.

If you want your air conditioner properly deep cleaned and mould-free, call Bailey and the team today on 0411 630 434 for a booking or to request a free quote in the contact form below.
