Living in Townsville’s tropical climate means your air conditioning works overtime to keep your home comfortable. But when was the last time you had your split system professionally cleaned? If you’ve noticed musty odors, reduced cooling efficiency, or that unsightly moldy appearance on your indoor unit, it’s time for a thorough clean.
At Zamp, we specialise in comprehensive split system cleaning that restores your air conditioning to peak performance. Here’s exactly what happens during our professional cleaning process.
Before We Begin: Safety and Preparation
Every job starts with safety. We isolate the power at the outdoor condenser unit and test to ensure it’s completely dead before beginning any work. As professional cleaners, we also wear respiratory protection due to the biological elements we encounter daily – mold, bacteria, and other contaminants that accumulate in neglected units.

To prepare for our arrival, we ask that you clear a one-metre space from the wall where your indoor unit is mounted. This gives us room to position our collection equipment and step ladder safely. We recommend removing any valuables from the immediate area and relocating sensitive items that might be affected by cleaning activity.
Step-by-Step: The Indoor Unit Deep Clean
Documentation and Disassembly
We begin every job by taking before and after photos of both the wall area and the unit itself, with the plastic casing both on and off. This documentation helps track the transformation and ensures we return everything to its original condition.
Next, we carefully remove the filters and outer plastic casing to access the internal components that need attention.

Protection Setup
Before any cleaning begins, we establish a controlled work environment. Our blue water collection bag is positioned to catch all dirty water and debris flowing from the unit. A drop sheet protects your furniture and flooring from any spray or dust, and we use protective pads on our step ladder to prevent damage to your walls or floors.
The Deep Clean Process
The heart of our service involves cleaning the evaporator coils – the delicate internal components where mold and bacteria love to grow. We use industry-standard, HVAC-approved pH neutral cleaning solutions specifically designed to neutralise bacteria, mold, and viruses while being safe for the sensitive coil materials.
Using a low-PSI pressure washer designed specifically for air conditioning components, we thoroughly wash the evaporator coils. The gentle pressure removes years of accumulated grime without damaging the delicate fins and coils.
While the internal components are being cleaned, we take the plastic casing components outside for a thorough wash, ensuring every surface is spotless.
Drainage and Finishing
A crucial but often overlooked aspect of air conditioning maintenance is the drainage system. We unblock the drain line to prevent water pooling or overflow, which can cause serious damage to your walls, plasterboard, and paint.
After cleaning, we use a professional blower to dry all plastic components thoroughly before reassembly. Every component is carefully reinstalled, and we conduct a final test to ensure your system is operating perfectly.
What About the Outdoor Unit?
While our focus is on the indoor unit where most problems occur, we also inspect your outdoor condenser unit if it’s accessible from ground level. Typically, the outdoor unit only requires attention if animal hair is blocking the grilles or if wasps have built nests on the fan blades – issues we’ll address with a simple rinse when necessary.
The Transformation You’ll Notice
The most dramatic change you’ll see is the removal of that black, moldy buildup that accumulates after years of exposure to our tropical moisture and heat. The before and after photos we take really showcase this transformation.
But the benefits go beyond appearance. Regular professional cleaning eliminates musty odors, increases your system’s operational efficiency, and prevents the unsightly moldy appearance that makes your air conditioning look neglected.

When to Call the Professionals
We recommend professional cleaning every 12 months, but certain signs indicate your system needs immediate attention:
- Musty, moldy, or foul odors when you first turn on your air conditioning or during operation
- Water pooling or overflowing from the indoor unit, which can indicate a blocked drain and lead to costly wall and paint damage
- Reduced cooling efficiency or higher electricity bills
- Visible mold growth on the unit’s exterior or around the vents
