Step by Step Guide on How to Clean Window Air Conditioner


The first step in cleaning your window air conditioner is to ensure that you have all the necessary tools and supplies. You will need a screwdriver, a brush or vacuum cleaner, a bucket, a scrub brush, a mild detergent, and warm water. Before starting, disconnect the air conditioner from the power source and remove it from the window.

Filter Cleaning

The filter is one of the most important parts of the window air conditioner, as it helps to trap dust and other particles. Remove the filter and clean it with warm soapy water, then rinse it with clean water and let it dry completely. You may need to replace the filter if it is too dirty or worn out.

Coil Cleaning

The evaporator and condenser coils of the air conditioner can collect dirt and debris over time, which affects the efficiency of the unit. Use a brush or a vacuum cleaner to remove any loose debris, then spray the coils with water to loosen any remaining dirt. Apply a coil cleaner and let it sit for a few minutes before rinsing with clean water.
