Your air conditioner will sometimes show signs that something isn’t working as it should. Knowing what to look for can help you decide when cleaning or inspection is needed.
If your AC takes longer than usual to cool the room or the airflow feels weaker, dirty filters or internal buildup may be restricting airflow. However, cooling problems can also have other causes.
A musty or unpleasant smell coming from your AC may indicate moisture, mold, or dirt buildup inside the unit. Cleaning may help when the odor comes from dirty components.
Water leakage may be caused by a clogged drainage pipe, dirty components, or an installation problem. It's best to identify the cause before deciding on the right solution.
