Danger - what you need to know about air duct cleaning
Share:

As you know it is extremely beneficial to have your air ducts cleaned. Clean air ducts help to protect your building occupants, improve indoor air quality, and ultimately lead to energy savings. But did you know that cleaning your air ducts can be problematic if not performed correctly?

How can air duct cleaning go wrong?
Hiring an inexperienced contractor has many potential repercussions. The number one concern is that inexperienced technicians can actually worsen air quality conditions, rather than improving it. Without proper cleaning protocol, they may unintentionally disturb resting particles and dust in the air ducts and force them into occupied spaces. If the proper steps are not followed, such as putting the system under negative pressure and placing filters over registers, duct cleaning could potentially release various allergens and pathogens into your indoor air, creating problems for occupants with severe allergy issues or compromised immune systems. Specific equipment and procedures must be in place to ensure air ducts are cleaned safely.
During the air duct cleaning process your entire HVAC system must be placed under continuous negative pressure by HEPA collection devices to ensure no dust or debris escapes into occupied spaces during cleaning. Technicians should clean all interior surfaces moving in the same direction as the flow of air and utilize a combination of brushes and power whips to remove the built-up dust and debris. In addition, an experienced technician will place filters on all supply and return registers as an extra measure of precaution to ensure debris does not escape during the cleaning process.

If this equipment is not used correctly, or if inappropriate equipment is utilized, an inexperienced technician may accidentally damage the HVAC system and ductwork itself. The key take away here is that air duct cleaning should only be performed by an experienced professional.

How can I ensure my air ducts are cleaned to the highest standards?

 

1. Hire a reputable contractor – Choose a company that is a member of NADCA (National Air Duct Cleaners Association) with an Air Systems Cleaning Specialist on staff. NADCA member companies are educated in the proper procedures and utilize the appropriate equipment to clean your HVAC system and ductwork.

 

2. Check their background – have they successfully worked in hospitals or other sensitive environments before? If so they may hold themselves to even higher standards of quality and infection control.

 

3. Ask for before and after photos – it never hurts to ask for this documentation. This way you have evidence of the improvements made in your air ducts, and can see the quality of the technicians work. Spot checking at random locations after cleaning is also a good way to verify consistent and thorough cleaning.
