How to Know When it’s Time to Clean your Air Ducts

The EPA recommends cleaning air ducts whenever there is a rodent/insect infestation, mold growth, or if the ducts are clogged with dust and debris.

Airborne particles can be released from dirty ducts and contaminate a HVAC system, or if moisture gets into the system mold can grow, and mold spores may be released into the air. In those situations, it’s crucial to have your facility’s ducts cleaned.

Dirty ducts can become a breeding ground for mold spores, bacteria and other particles, which can lead to poor indoor air quality.

If your facility is faced with a dirty duct problem and you have to hire an air duct cleaning service, what should you expect from the company?

The duct cleaning service provider should:

  1. Open all ports and doors to ensure the entire system is thoroughly cleaned and inspected.
  2. Be sure to inspect the system before cleaning to look for asbestos-containing materials. Materials should not be disturbed and should only be removed by contractors who are specially trained in asbestos removal.
  3. Use a vacuum that will vent particles outside of the building.
  4. Protect furnishings and carpeting throughout the cleaning procedure.
  5. Brush duct surfaces as well as use contact vacuum cleaning to remove all dust and particles.
  6. Protect the ductwork by sealing and re-insulating access holes and use soft-bristled brushes to clean fiberglass duct board or metal ducts lined with fiberglass.

Facility managers may also choose to use their own crews to handle air duct cleaning. Want to know more about this topic? Call MaintenX today!
