Why Regular Air Conditioner Cleaning Is Important

Skipping regular cleaning of your air conditioner can lead to several issues: mould and bacteria build-up, polluted air, health issues such as allergies or respiratory discomfort, higher energy consumption, costly repairs, and a reduced lifespan of the unit. To avoid these problems, it’s essential to clean your air conditioner at least every three months. If you use it daily or live in a dusty area, monthly cleaning is recommended.

Essential Cleaning Tools

Before you begin, gather the following tools, which you likely already have at home: screwdriver, vacuum cleaner with a brush attachment, soft brush, mild detergent, clean dry cloth, bucket of warm water, and a wet-dry vacuum or pipe cleaner for clearing the drain line. Having the right tools ensures you can complete the task efficiently and safely. These tools are especially helpful when cleaning the filters and coils, as we’ll explain below.

How to Clean the Air Conditioner at Home: Step-by-Step Guide

1. Turn Off the Power

Safety should always come first. Before cleaning the air conditioner, switch off the power at the mains to avoid any electrical hazards. Most air conditioners have a dedicated switch; ensure it’s turned off before proceeding. Tip: Check the user manual for specific instructions on turning off your air conditioner.

2. Clean and Remove the Filters

The air filters trap dust and debris, ensuring clean air circulation. Over time, clogged filters can block airflow and reduce the unit’s cooling efficiency. Here’s how to clean the aircon filter: Open the front panel of your air conditioner and gently slide out the filters. For washable filters, use a vacuum cleaner to remove surface dust, then soak the filters in warm water with mild detergent for 15–30 minutes. Rinse thoroughly under running water and let them air dry completely before reinserting them. For non-washable filters, replace them according to the manufacturer’s instructions. Regular filter cleaning can improve your air conditioner’s efficiency by up to 15%.

3. Clean the Evaporator and Condenser Coils

The coils play a crucial role in cooling by absorbing and releasing heat. Dirty coils can reduce efficiency and strain the unit. Locate the evaporator coils inside the indoor unit and the condenser coils in the outdoor unit. Use a soft brush or a vacuum cleaner to remove dust and debris gently. Avoid using sharp objects to prevent damage. For stubborn dirt, use a coil cleaner spray designed for air conditioners. Follow the instructions on the product for best results. Cleaning these coils improves airflow, cooling capacity, and energy efficiency. Learn more about cleaning air conditioner coils here.

4. Clear the Drain Line and Pan

The drain line removes condensation from your air conditioner. A clogged drain line can cause water leakage and mould growth. Use a wet-dry vacuum to unclog the line, or flush it with a mixture of warm water and vinegar. Clean the drain pan with a cloth and ensure no standing water remains. Regular cleaning prevents unpleasant odours and water-related issues.

5. Reassemble and Test

After completing the cleaning process, reassemble the filters and panels securely. Turn the power back on and test the air conditioner to ensure it’s functioning correctly. Look for any unusual noises or reduced airflow. If you notice issues, check that all components are properly installed.
