They actually remove some of the metal, leaving the surface pitted. This prevents water from easily shedding off the fins. These water droplets attract microbial growth and feed it and water droplets are then carried into the air stream and deposited downstream into the ducts, supporting secondary growth. In addition, these cleaners will give off fumes that are air contaminates. Coil cleaners which fall in the category of pH Balanced will not damage the coil while cleaning or release toxic fumes.
Most people believe that systems free of growth operate more economically and last longer.
A. Most corrosion in HVAC systems is caused by sulfuric acid secreted by common bacteria that chemically combines sulfur from the air with hydrogen and oxygen from water. A national authority on the impact of bacterial and fungal contamination on indoor air quality, Robert G. Baker sits on several key industry technical committees. Mr. Baker, Chairman and CEO of BBJ Environmental Solutions, Inc., founded the business in 1993 following the EPA's registration of the company's central product, BBJ MicroBiocide , a unique product that controls microbial contamination and that can make indoor air safer to breathe. Baker's experience with hospital disinfectant manufacturing and as a high-ranking hospital administrator, corporate manager and planner has contributed to his new venture's success.
