Before beginning the cleaning process, it's vital to ensure that all equipment is ready and functioning properly. Preparation not only ensures efficiency but also maintains the safety of technicians and property.
-
a. Gather all necessary tools.
Begin by assembling all tools before approaching the vent. This avoids interruptions during cleaning and ensures all parts of the vent system are properly serviced.
Essential Tools Include:
• HEPA-rated vacuum/dust extractor: Ensures fine particles are captured without re-circulating them into the air.
• Rotary brush kit with flexible rods: Dislodges dust and lint from vent walls, especially in long duct runs.
• Drill (corded or battery-powered): To power rotating brushes.
• Vent inspection camera: Optional but highly recommended for before-and-after assessments.
• Crevice tools and nozzle attachments: For tighter or oddly shaped duct segments.
• Compressed air tools (e.g., skipper balls): For pushing dust out of long or overhead runs.
• Protective gear:
i. Safety goggles (to guard against flying debris)
ii. Respirator mask (especially in enclosed spaces or older homes with possible mold or allergens)
iii. Gloves (for grip and protection from sharp vent edges)
• Extension cords & power strips: With surge protection, suitable for industrial environments.
• Drop cloths or plastic sheeting: To protect flooring or customer property.Essential Tools Include:- HEPA-rated vacuum/dust extractor: Ensures fine particles are captured without re-circulating them into the air.

Vacuum motor operation:
- i. Turn on and listen for smooth operation.
- ii. Check suction power using hand or test material.
-
Filters:
- i. Inspect HEPA or primary filters for saturation or clogs.
- ii. Replace or clean filters as required.
-
Hoses and seals:
- i. Look for wear, cracks, or improper sealing at joints.
- ii. Tighten or replace connections to avoid leaks.
-
Collection bin:
- i. Empty any prior dust; start with a clean bin for accurate measurement of new debris collected.
-
Power supply:
- i. Test outlets for safe voltage and grounding.
- ii. Confirm that extension cords are not frayed or overloaded.

c. Ensure Safety Protocols Are in Place
-
Technician Safety:
- i. Wear eye protection and respirator at all times when handling dry vent dust — it's flammable and may contain mold, dander, or bacteria.
- ii. Avoid loose clothing or jewelry when using rotary tools.
-
Site Safety:
- i. Post signage if working in commercial areas or shared buildings.
-
ii. Inspect surrounding appliances:
- Ensure the dryer is disconnected from the power or gas source.
- If gas-powered, confirm there's no active gas flow before proceeding.
-
Vent access:
- i. Confirm whether the vent exits through a wall or roof.
- ii. Place ladders securely if roof access is needed and follow fall safety procedures.
-
