Regardless of whether you clean your air ducts yourself or hire a professional contractor, the question is, what is the best air duct cleaning equipment, chemicals and proper cleaning methods?

Do you really need specialized equipment for air duct cleaning?


Air duct cleaning equipment, chemicals and proper cleaning methods have been described in many sources; however, there is no consensus if you need to clean air ducts regularly if you need to employ a professional company.

The most important point is that all the parts of the system must be cleaned; otherwise, recontamination is possible that eliminates the benefit of cleaning.

If you want to clean your air ducts yourself the following equipment will be helpful:

  • A sturdy ladder
  • Screwdriver
  • Long-handled brush
  • Broomstick
  • Duct tape
  • Rags and towels
  • A vacuum cleaner with a hose attachment
  • Mop
  • Bucket of water

If you want to clean the system but also clean it professionally, you can rent professional equipment. However, if the system has:

  • Rats or insects in it
  • Visible mold and a strong odour
  • Complicated parts and it is not possible to clean the whole system

In these cases, hiring a professional service is recommended. A professional service provider will use professional equipment and cleaning materials.

You can find more information about air duct cleaning equipment, chemicals and proper cleaning methods on EPA and NADCA websites.

What chemicals to use?


All chemicals used for HVAC system cleaning must be EPA registered. Never use chemicals that don’t have HVAC applicability instructions on them. If you buy a professional service, make sure that a contractor uses EPA registered, and better environmentally friendly products. Here at Golden Line Green Care, we only use environmentally friendly products to clean your HVAC systems.

Pay attention to specific HVAC related directions; the products will not be effective if not applied as instructed. Cleaning HVAC system is time-consuming and costly if you hire a professional company, thus make sure to choose the professional company with excellent feedback from customers.  If you do your cleaning yourself, pay attention to air duct cleaning equipment, chemicals and proper cleaning methods described in this blog post.

Proper cleaning methods


NADCA (the HVAC Inspection, Cleaning and Restoration Association) published a range of information about air duct cleaning equipment, chemicals and proper cleaning methods.

As we mentioned before, the whole system must be cleaned, including:

  • Air ducts
  • coils
  • drain pan
  • registers
  • grills
  • air plenum
  • blower motor and assembly
  • heat exchanger
  • air filter
  • air cleaner

To remove contaminants that have been accumulating for a long time and probably hard to clean, you must first agitate them to break contaminants loose. To do this, you can use brushes, air whips and compressed air nozzles or “skipper balls” or other equipment.

After contaminants break loose, they can be collected. The whole HVAC system is put in negative pressure so that even small particles can be removed from the system.

Whenever possible, you will access the hidden parts from existing holes; ducts, return grills, diffusers are examples. However, sometimes it is needed to open service holes to clean the whole system thoroughly.
