Air conditioners are not only effective in facilitating cool air but also in removing excess moisture, dehumidifying the room, and removing mold and pollutants from the air. Such functions help manage asthma attacks and other respiratory conditions among those prone to these diseases. Maintaining an air conditioner is important to ensure its optimal functioning over time. With that in mind, here are 13 common mistakes to avoid that can increase energy and money wastage: Not cleaning the coils and fins of the AC The coils and fins of an air conditioning system help absorb heat effectively. With time, dust and grime accumulate in the air conditioner’s coils and fins, reducing its efficiency and increasing maintenance costs in the long run. Therefore, it is important to regularly clean the coils and fins of an AC, particularly when the weather is windy or stormy. Ignoring the drain Drains redirect accumulated water outside the premises where they are installed and prevent the development of mold and mildew. If the air conditioner’s drain gets clogged with time, it can cause severe damage to the surrounding areas, including walls and floors. One should check the AC’s drain every now and then and promptly treat any drainage issues to prevent such damage.
