How To Clean Split Air Conditioners

When it comes to cleaning your split AC indoor unit at home, it’s crucial to know the proper steps to take. Not only will this help ensure your AC unit operates at maximum efficiency, but it will also help improve the air quality in your home. In this article, we’ll walk you through the steps to effectively clean your split AC indoor unit at home.

Understanding Your Split AC Indoor Unit

Before we dive into the cleaning process, let’s briefly discuss what your split AC indoor unit is and how it works. A split AC system is composed of an outdoor unit and an indoor unit. The indoor unit consists of a heat exchanger, fan, and filter. The heat exchanger is responsible for cooling the air in your home, while the fan circulates the cooled air. The filter helps trap dust, dirt, and other pollutants from the air.

Step 1: Turn Off the Power

Before you start cleaning your split AC indoor unit, the first step is to turn off the power. This is important to prevent any accidents or injuries while cleaning. You can turn off the power by either unplugging the unit or switching off the circuit breaker.

Step 2: Remove the Air Filter

The next step is to remove the air filter. The air filter is usually located behind the front panel of the indoor unit. To remove the filter, gently slide it out of its slot. Once you have removed the filter, use a vacuum cleaner or a soft brush to clean it. If the filter is too dirty, you may need to replace it with a new one.

Step 3: Clean the Air Conditioner Coils

The air conditioner coils are responsible for cooling the air in your home. Over time, dirt and dust can accumulate on the coils, reducing their efficiency. To clean the coils, you can use a soft brush or a specialized coil cleaner. Gently brush the coils to remove any dirt or dust. If you’re using a coil cleaner, make sure to follow the instructions carefully.

Step 4: Clean the Drain Pan and Drain Line

The drain pan and drain line are responsible for removing condensation from the indoor unit. Over time, algae and mold can grow inside the drain line, leading to clogs and leaks. To clean the drain pan and drain line, mix equal parts water and bleach and pour it into the drain pan. Allow the solution to sit for 30 minutes before flushing it out with water. You can also use a specialized drain cleaner to clear any clogs.

Step 5: Reassemble the Indoor Unit

Once you have completed the cleaning process, it’s time to reassemble the indoor unit. Start by replacing the air filter and securing the front panel. Make sure all the screws are tightly secured and the filter is properly installed. Finally, turn on the power and test the unit to ensure it’s working properly.

Conclusion

Cleaning your split AC indoor unit is essential to ensure it operates at maximum efficiency and provides clean air for your home. By following these steps, you can effectively clean your split AC indoor unit at home. Remember to turn off the power, remove the air filter, clean the coils, clean the drain pan and drain line, and reassemble the indoor unit. By taking these steps, you can help extend the life of your AC unit and improve the air quality in your home.
