The Coils

AC coils are among the dirtiest parts of the unit. Dirty air flows through these coils, causing dust, dirt, and debris to build upon its surfaces. Over time, dirty coils push the unit to work harder and reduces the ability to provide a cool atmosphere. 

In extreme cases, dirty coils can completely block the airflow and potentially damage the whole air conditioner unit. It means you have a more expensive repair bill to pay. How to clean air conditioner coils?
