Our Cleaning and Filter Repair Process

1

Full System Evaluation

We start every service with a thorough inspection to identify dust build-up, filter blockages, leaks, or restricted airflow that may be affecting your system.


2

Filter Cleaning & Replacement

Your filters are the front line of your AC system. We clean reusable filters and replace worn or damaged ones to ensure clean, uninterrupted airflow and healthier indoor air.


3

Evaporator & Condenser Coil Cleaning

Dusty coils can reduce efficiency and force your system to work harder. We clean both indoor and outdoor coils using safe, effective methods to restore your system's heat exchange performance.


4

Drainage Line Flushing

We clear out condensate lines and pans to prevent clogs, water damage, and foul odours. This step is essential to avoiding leaks, especially during summer use.


5

Odour & Mould Elimination

Musty smells or visible mould are signs your system needs a professional clean. We sanitise affected areas and improve your indoor air quality with eco-safe solutions.


6

Performance Testing & Advice

Once cleaned, we test your system’s airflow and temperature output. If filter damage or internal wear is spotted, we’ll advise on suitable air conditioning filter repairs or replacements.
