Begin the internal duct cleaning by first taking 'before' pictures of the branch ductwork through the open vent. Then, a specialized air washing tool is inserted into each branch line to blast away loose dust and debris. If necessary, a cable-driven rotating brush is used to scrub the interior surfaces of the ductwork, dislodging stubborn buildup. Another air wash then pushes all the loosened particles down the branch line towards the main negative air vacuum system for collection.

FAQs

Many specialized tools are listed, do I really need all of them, especially the endoscope camera?

Yes, tools like the endoscope camera (borescope) are highly recommended to effectively inspect and ensure thorough cleaning, especially in hard-to-reach areas of your ductwork. The shop vacuum with a long extension hose is crucial for debris removal, and proper sealing materials are essential for containing dust.

What are the most important safety precautions for this project, and is it truly beginner-friendly despite being a 2-day job?

Wear appropriate personal protective equipment like an N95 mask, gloves, and eye protection to avoid inhaling dust and irritants. While the steps are straightforward for a beginner, the project is labor-intensive and time-consuming, requiring patience and attention to detail over two days.

What are the most common mistakes DIYers make when cleaning air ducts, and how can I avoid them?

Common mistakes include inadequate sealing of vents, not thoroughly cleaning the blower motor, and failing to remove all debris from branch ducts. To avoid these, meticulously follow the sealing steps, use your endoscope to verify cleanliness, and ensure your vacuum has strong suction with appropriate attachments.

The sanitization step is optional; how do I decide if it's necessary, and are there alternative products to use?

Sanitization is recommended if you've had mold issues, pets, or strong odors in your home, as it helps eliminate bacteria and fungi. If opting for sanitization, always choose an HVAC-approved disinfectant spray. Ensure good ventilation during and after application, and follow the product's instructions carefully.

We will start by taking our before pictures of the branch ductwork, then we will air wash the ductwork. If needed, we will use our cable driven brushes to scrub the ductwork even more and then air wash again to push all the particles down the ductwork to the main negative air vacuum.
