Duct Cleaning: Containment and Safety

Professional duct cleaning safety helps restore your HVAC system and air ducts to like-new condition by removing built-up dust, dirt, pet dander, mold, and other pollutants. However, without proper containment and safety measures in place, the duct cleaning process itself could potentially contaminate your home's air supply with the very particles it aims to remove.

•Containment – The use of shields, filters, seals and tarps to contain any debris stirred up during cleaning within the ductwork. Containment prevents contaminants from spreading into the living spaces of your home. Reputable duct cleaners will contain all dust and particles before moving on to other sections of the duct system.

•Air-admission prevention – Strict protocols to ensure that no unfiltered air is sucked into or blows out of the ducts during cleaning. This includes sealing air inlets, outlets, joints, seams, boots and any other openings with barrier tape, plastic sheeting and filters.

•Negative air pressure – A high-volume negative air machine should maintain negative pressure throughout the containment area. Negative pressure pulls air in instead of pushing it out, enabling tighter control of airflow and containment.

  • proper filter installation – Wide pleat HEPA filters install on all supply, return and exhaust ducts, air handlers, furnaces, air conditioners and ventilation systems before cleaning begins and remaining in place throughout the process.

•Safety equipment – Respirators, coveralls, gloves and goggles help ensure the health, safety and hygiene of technicians working with potentially hazardous particulates. A reputable company’s technicians will wear appropriate safety gear at all times during duct cleaning.

Duct cleaning should leave your air ducts hygienic and your home fresh, not expose you to the very particles .Look for full containment, safety practices and negative pressure to avoid health risks and achieve truly clean air. With the comprehensive approach provided by a professional duct cleaning company, you can maintain pristine air quality and respiratory health for years to come.
