quality HVAC system cleaningA building’s HVAC system acts like its “lungs and circulatory system.” Dirty air ducts, coils and condensers can trap and collect bacteria and mold. Older buildings can harbor asbestos or lead that can be broadcast throughout buildings via their HVAC systems as well.  If your building’s occupants are sensitive, air quality is a particular concern.  Airborne contaminants can aggravate existing pulmonary issues, trigger allergic reactions or further spread mold and bacteria throughout the system. 

Some commercial buildings lack efficient air handling systems or have ineffective filtration systems that can cause a large amount of particulate buildup inside the system and throughout the building.

ACTS technicians have the expertise and equipment necessary to address these issues on a larger, more complex scale, providing full hvac system cleaning.
