Commercial Air Duct Cleaning

Many people suffer from allergies and excessive dust and particulates in the air and need to do something to improve their indoor air quality. We can help.

What Is Different About Commercial Compared To Residential Air Duct Cleaning?

The contractor should be aware:

  • The work is usually performed after hours and weekends

  • There may be an attic return instead of ducted

  • The interior fiberglass insulation may be deteriorating and need recoating

  • The ducts may have turning vanes, fire dampers and smoke detectors inside

  • There may be VAV mixing boxes in a medium or high-pressure system

  • There may be reheat coils, HEPA filtration

  • There is always some kind of fresh air system, sometimes with an ERV

  • More OSHA demands including Lock-out/Tag-out and fall safety

  • Some units, plenums, and even trunks are large enough to climb inside

  • Testing and balancing (TAB) procedures

  • Some facilities have unique demands such as clean rooms, security concerns

  • Working with an Indoor Environmental Professional protocol

  • The National Air Duct Cleaners Association (NADCA) standards and certifications

Some duct cleaners may not be familiar with the unique challenges commercial duct cleaning presents. A thorough interview is necessary to determine knowledge, experience, and capacity.

Professional Air Duct Cleaning

According to NADCA, all duct cleaning should be performed while the system is under negative air pressure (either exhausted outside or through HEPA filtered machines) and agitated with whips, brushes or skipper balls. No antimicrobial agents, sealers, sanitizers or deodorizers should be sprayed or fogged inside the ductwork to compensate for substandard cleaning or as a substitute when ductwork should be replaced.

How to determine if your air ducts need cleaning (from the DOHS Fact Sheet)

  • Are there known or observed contaminants in the ductwork?

  • Have you confirmed the type and quantity of the contaminants based on testing or observation?

  • Are the contaminants (or their by-products) capable of entering occupied spaces

  • Have you identified and controlled the source of contaminant?

  • Will the duct cleaning effectively remove, inactivate or neutralize the contaminant?

  • Have you considered other options, such as removing the ductwork?

  • Is duct cleaning the only (or most effective) solution?
