help keep visible

help keep visible mildew from returning. But when mold spores get into the air conditioning system, they can settle in the air conditioning ductwork along with dust and other contaminants. Air conditioning duct systems, especially in Florida's humid climate, can be virtual incubators for microbial pollutants such as mold and bacteria. With the alternating high and low humidity conditions which regularly occur in air conditioning ducts during air conditioner operation, molds will grow, spread, produce spores and distribute the spores throughout a house. Mold contamination in air conditioning ducts poses a serious problem. Inhibiting Mold Growth in Air Conditioning Ducts To effectively prevent conditions that lead to air condition ductwork contamination, two considerations must be made: 1. Keep the ducts free from dirt and spores. 2. Check and repair any leaks in ducts that might introduce dirt and moisture.
