How Often Should You Service a Split System?

**What you can do yourself (monthly):** - **Clean the filters:** Open the indoor unit front panel, remove the mesh filters, and wash them under the tap. Let them dry completely before reinserting. This takes 5 minutes and is the single most important maintenance task. - **Wipe the indoor unit:** A damp cloth on the exterior prevents dust buildup. - **Check the outdoor unit:** Make sure nothing is blocking airflow around the outdoor unit — trim plants, remove debris, and check for leaf buildup in the fins. **What a professional does (annually):** - Check refrigerant levels and top up if needed - Inspect and tighten electrical connections - Clean the indoor coil and outdoor coil fins - Check and clear condensate drainage - Inspect the circuit board for signs of gecko damage or wear - Test compressor and fan operation - Check system performance against manufacturer specs - Verify thermostat/remote accuracy **What happens if you don't service:** - Clogged filters reduce efficiency by up to 30% - Dirty coils cause the compressor to work harder, shortening its life - Blocked drainage causes water to overflow inside your home - Undetected refrigerant leaks reduce cooling and can damage the compressor - Gecko damage goes unnoticed until the board fails
