Mold Removal In HVAC Systems

When HVAC systems are contaminated with mold and microbial contamination, IMC has the experience and qualifications to provide for proper containment and cleaning of the air conveyance system. Microbial contamination includes a diverse group of organisms such as fungi, mold, and bacteria. Examples may include mold, sewage, legionella bacterium (may cause Legionnaires’ Disease) and Histoplasma capsulatum (disease causing fungus found in pigeon, bat and bird droppings). IMC has the experience and knowledge to provide the proper isolation, removal, and disposal of these microbial contaminants in a safe and efficient manner.

Abatement of any contamination is only one step of the process. The presence of active microbial contamination may be an indicator of more severe problems that may be occuring in and around the air conveyance system. It is extremely important that the problems which led to the microbial contamination be addressed. IMC technicians may help in this process, but we recommend that certified Industrial Hygienists and consultants perform the sampling and investigative expertise involved to provide a more complete investigation.

IMC uses many techniques for microbial remediation depending on the surface of the ductwork where the contamination exists. Porous surfaces are typically the most susceptible to contamination and may require the removal and disposal of the internal lining insulation of the ductwork, or air handling unit.

One of the most important steps include containment of the work area to prevent the spread of the contamination. IMC utilizes HEPA-filtered (high efficiency particulate air) scrubbers to control the air pressure of the air conveyance system and the work area and HEPA-filtered vacuums to provide source removal of any contamination. Other protocol common to the asbestos and lead abatement industries are utilized to isolate and maintain a work area. After a complete source removal of the contamination, sometimes it is necessary to treat the affected areas with an antimicrobial coating product, or a sanitization chemical product.

IMC technicians are trained in various abatement and chemical treatment procedures and comply with all OSHA Safety requirements including Respiratory protection, Hazardous Materials communication, and proper Personal Protective Equipment. Site specific Safety Analyses are performed to ensure worker and occupant safety.

IMC has completed numerous microbial abatement projects throughout the Mid-Atlantic region at residences, office buildings, schools, hospitals, government facilities and industrial sites. Please ask your IMC representative for further information.
