Our duct cleaning service includes a thorough washing of the indoor coil and drain pan to eliminate mold and algae.
Taking the supply grilles off and running a vacuum up into the ducts is mainly a cosmetic service. The source of odors and respiratory irritants is typically dirt and mold buildup on the indoor cooling coil. The indoor coil is a radiator with cold fluid on the inside to cool and dehumidify the air inside your home. As a result, it is covered in condensation when your air conditioner is running. This allows dust and lint to cling to the small spaces between the fins of the coil.
The combination of dirt, water (condensate), and a warm, dark space (your attic) results in mold and algae formation inside the coil.
The presence of mold and algae create odors, aggravate your allergies, and reduce your air conditioner's ability to circulate air. It is recommended to have the coil washed every few years to keep the air conditioner cooling well and to keep odors and allergens at bay.
