Sick Building Syndrome

In a commercial environment, it is extremely important for air delivery systems to be clean and efficient, delivering pure, clean air to everyone in the building. Studies have proven that indoor air can be several times more polluted than outdoor air. Poor air quality caused by issues with the building’s HVAC systems is frequently cited as a major contributor to sick building syndrome: a medical condition in which multiple occupants of the same building suffer from health problems, linked directly back to time spent within the building. Sick building syndrome can be caused by several things, including contaminants and poor building ventilation.

Value to its occupants

This means that duct cleaning and air purification services can be of tremendous value to a business and its staff, helping to improve workplace efficiency through the overall health of the workforce.

The current COVID-19 pandemic has increased the awareness of improving indoor air quality. It has brought into focus the spread of virus, bacteria and other pathogens in living and working spaces and the risk they pose for employees, workers, residents and consumers. In this situation, we cannot stress enough the importance of cleaning the ducts of air conditioning systems.

Duct Cleaning & Standards

Duct cleaning helps eliminate bacteria and particulate debris which form inside ducts over a period of time. Regular duct cleaning ensures that the occupants breathe clean and pollution-free air. The National Air Duct Cleaners Association (NADCA) and many other global associations recommends that the complete HVAC system should be cleaned to prevent re-contamination.

NADCA ACR 13 Standards The NADCA Standard for Assessment, Cleaning & Restoration of HVAC Systems is the internationally recognized industry standard for HVAC cleaning and restoration.

Three methods of cleanliness verification as per NADCA ACR 13 Standards.

NADCA ACR 13  standards has five sections namely –

  • Inspection
  • Work Plans
  • Engineering Controls
  • Cleaning And Restoration Procedures
  • Cleanliness, Verification And Documentation.

NADCA ACR 13 Standard provides practical, reliable and Industry-backed information for-

  • Assessing new and existing HVAC systems.
  • Evaluating & verifying the cleanliness of HVAC system components.
  • Guiding the cleaning and restoration of HVAC systems to a specific level of cleanliness.
  • Helps determine the need to clean.
  • Helps you to have a clear scope of work.
  • Provides protocols to protect the safety of building occupants & prevents cross contamination.
  • Helps you understand proper cleaning procedures.
  • Provide quantifiable methods for verifying cleanliness.

Determining need to clean

It is recommended that HVAC systems be cleaned when one or more of the following conditions exist in the HVAC system.

  • Contaminated with an accumulation of particulate;
  • Performance is compromised due to contamination build-up;
  • Has been determined to be source of unacceptable odors;
  • Discharging visible dirt or debris into the conditioned space;
  • Has been contaminated as a result of fire, smoke or their byproducts;
  • Has become contaminated with construction dust and/or other debris;
  • Mold contamination conditions have reached Condition 2 or 3;
  • Deterioration of fiber glass duct liner, duct board or other porous components.

New dynamics of IAQ

With the advent of the HVAC system, new IAQ dynamics was born and these lungs of the building had to be cleaned in a safe secure manner. Industry professional got together and formed an association and the first standards of HVAC Duct Cleaning were created.

The need for cleaning may arise when the HVAC system operation has resulted in the build-up of particulate and debris which may adversely impact the indoor environment and performance of the system. In such cases, the HVAC system will require cleaning activities beyond those performed in normal HVAC mechanical maintenance and servicing.
