Dirty AC coils are often the cause of odors in an AC unit.
The coils inside of your AC function to cool the air in your home. Due to the high humidity nature of the coils, it is often one of the dirtiest parts of an AC unit and a frequent cause of odors in your home/ducts.
Buildup on the coils can also lead to lessened efficiency of the unit, preventing the fins from cooling properly. Using a specialized soft brush/cloth, along with foaming cleansers, we are able to safely and effectively clean the coils.
