Well, professional air duct cleaners use a range of equipment, from small handheld tools to heavy-duty machinery. Inspection tools like mirrors, periscopes, and even CCTV cameras help identify and address issues in hard-to-reach areas of the duct system. 

Basic cleaning tools include brushes, vacuums, and agitation devices, all designed to effectively remove accumulated dust, dirt, and contaminants.

  • Pets
  • Smokers in the household
  • Recent renovations
  • Visible mold growth in the ducts
  • Allergies or respiratory problems

However, cleaning may not be necessary if:

  • Your ducts are well-maintained and sealed.
  • You don’t have any of the risk factors mentioned above.

Choosing a Duct Cleaning Service Provider

Choosing the right company to clean your ducts is super important for a good cleaning job. Here’s a step-by-step guide on how to pick the right air duct cleaning service provider:

Ask Friends and Check Online

  • Ask your friends or neighbors who recently got their ducts cleaned for suggestions.
  • Look online for reviews and stories from other people who used the same service.


Avoid Exaggerated Health Benefit Claims

  • Be careful if the company makes exaggerated claims about the health benefits of duct cleaning. Look for realistic and evidence-based information.

Know About Chemicals Used

  • Understand the good and bad sides of using chemicals in duct cleaning. Only agree to it if you know why and what might happen.

Check if They Follow the Rules

  • Make sure the company follows the rules and recommendations from groups like the National Air Duct Cleaners Association (NADCA).
  • Ask if they do things right for ducts with special linings or materials.

Chat with the Cleaners

  • Talk to the people who will clean your ducts. Ask if they’ve done jobs like yours before.
  • Find out how they make sure your home and pets stay safe during the cleaning.

Check Their License

  • See if the company has the right license to do this work. Some places need special licenses for duct cleaning.

Get Everything in Writing

  • If they charge by the hour, ask how long it will take and get it in writing.
  • Before they start, get a paper saying how much it will cost and what they will do. This avoids surprises later.

Check with Consumer Affairs or BBB

  • Contact your local consumer affairs office or Better Business Bureau to see if anyone complained about the companies you’re thinking about.

What to Expect From an Air Duct Cleaning Service Provider

If you decide to get your ducts cleaned, here’s what the cleaning company should do:

  • Open Access Points: They should open doors or ports to clean the whole system and check it.
  • Inspect for Asbestos: Before cleaning, they must check for asbestos materials in the heating and cooling system and not touch or remove them unless they’re experts.
  • Use Proper Vacuum Equipment: They should use vacuums that push out particles outside your home or high-efficiency ones if the air goes inside.
  • Protect Your Stuff: Your carpets and furniture should be safe during the cleaning.
  • Brush and Vacuum: They will use brushes and vacuums to clean the duct surfaces properly.
  • Use Soft Brushes for Certain Ducts: Soft brushes are used for ducts made of fiberglass or lined with fiberglass inside. For flex ducts, it might be easier and cheaper to replace them.
  • Seal Access Holes: They’ll make sure to seal and insulate any holes they make during the cleaning so no air escapes.
  • Follow Cleaning Standards: They need to follow the standards set by NADCA for duct cleaning and NAIMA’s recommendations for ducts with fiberglass lining or constructed with fiberglass duct board.
