Why Winter Maintenance Matters for Your Air Conditioner Many Sydneysiders assume air conditioners can simply be switched off and forgotten during winter. However, neglecting your unit can lead to dust buildup, mould growth, and costly repairs. A little effort now keeps your system efficient and prevents breakdowns when you need it most. Energy savings: A clean unit uses less power when summer rolls around. Longevity: Regular care can add years to your air conditioner’s lifespan. Air quality: Maintenance reduces allergens and mould in your home. Step-by-Step Winter Maintenance Tips Here’s how to get your air conditioner ready for Sydney’s cooler months. These steps are simple enough for anyone to follow, no technical skills required. 1. Clean or Replace the Filters Dirty filters are the number one cause of air conditioner issues. Over summer, they collect dust, pet hair, and debris, which can clog the system if left unchecked. Turn off the unit and locate the filter (check your manual if unsure). Remove the filter and rinse it with warm water or vacuum it gently. If it’s damaged or heavily soiled, replace it with a new one—available at most hardware stores. Pro tip: Clean filters every 3 months, even during winter, if you use the unit for heating. 2. Clear the Outdoor Unit Sydney’s autumn leaves and winter winds can leave your outdoor condenser covered in debris. A blocked unit strains the system and reduces efficiency. Switch off the power to the unit. Remove leaves, twigs, and dirt with a soft brush or hose (avoid high pressure). Trim back any nearby plants to ensure good airflow. 3. Check for Leaks and Drainage Issues Winter rain can expose drainage problems in your air conditioner. A blocked drain can cause water damage or mould inside your home. Inspect the drain pipe (usually near the outdoor unit) and clear any blockages with a wet/dry vacuum or a plumber’s snake. If you spot leaks, it’s worth calling a professional—find trusted local services at elyment.com.au. 4. Cover the Outdoor Unit (Optional) While not essential, covering your outdoor unit can protect it from Sydney’s winter weather. Use a breathable, waterproof cover to prevent rust and pest infestations. Avoid plastic tarps, as they trap moisture and encourage mould. 5. Schedule a Professional Service For peace of mind, book an annual service with a licensed technician before winter hits. They’ll check refrigerant levels, electrical components, and overall performance—something DIY can’t fully cover. Key Takeaways for Sydney Homeowners Here’s a quick summary of what you need to know: Clean or replace filters to boost efficiency and air quality. Clear debris from the outdoor unit for better performance. Check drainage to avoid water damage. Consider a cover and a professional tune-up for extra protection.
