Step 1: Safety First
Before diving into cleaning, always prioritise safety. Turn off the power supply to the air-conditioner at the main circuit breaker. Additionally, ensure you have all necessary personal protective equipment.

Step 2: Exterior Cleaning
Start by cleaning the exterior components. Wipe down the unit with a damp cloth to remove dust and debris. Trim any vegetation around the outdoor unit to ensure proper airflow. Make sure the unit is on a level surface to prevent any strain on the components.

Step 3: Filter Cleaning
The air filter is a critical component responsible for trapping dust and contaminants. Remove the filter according to the manufacturer’s instructions. Clean reusable filters by vacuuming or washing them with mild soap and water. For disposable filters, replace them with a new one.

Step 4: Coil Cleaning
Over time, the evaporator and condenser coils may accumulate dirt and grime, hindering the heat exchange process. Use a soft brush or a vacuum cleaner to remove debris gently. For more stubborn dirt, a mixture of mild detergent and water can be applied. Ensure the coils are dry before reassembling.

Step 5: Fin Cleaning
The aluminium fins on the coils are delicate and can easily bend, affecting the system’s efficiency. Straighten any bent fins using a fin comb or a gentle touch. Be cautious not to damage the fins in the process.

Step 6: Drain Cleaning
Condensate drains can become clogged over time, leading to water damage and increased humidity. Clear the drain channels using a stiff wire or a mixture of bleach and water to prevent clogs.

Step 7: Duct Inspection
Inspect the air ducts for any visible signs of mould, dust, or debris. If necessary, hire a professional duct cleaning service to ensure the entire system operates at peak efficiency.

Step 8: Check Refrigerant Levels
Low refrigerant levels can impact the system’s cooling capacity. If you notice decreased performance, contact a qualified technician to check and replenish refrigerant levels.

Regular split system air-conditioner cleaning is a simple yet effective way to ensure optimal performance, energy efficiency, and a healthier indoor environment. By following these steps, you can extend the lifespan of your unit and enjoy the comfort of a well-maintained cooling system. If in doubt or for more complex tasks, always consult with a professional HVAC technician to ensure the longevity and efficiency of your air-conditioning system.

Now you know what to do, but having the time to actually do it is another thing. Many of you are time poor so please don’t forget to consider letting us do it on your behalf. We can arrange a thorough and professional clean of your air-conditioning units by trained and experienced technicians.
