Our residential air duct cleaning method

  1. We arrive at your home in our 14 ft diesel cube truck in clean uniform shirts.

  2. We do a walk-through with the property owner to count the number of vents and explain in detail how we will clean your duct system. We wear booties to protect your carpets.
  3. We bring in tarps and corner protectors to protect your floors and walls to the basement.
  4. Our tools and air line are brought inside your home.
  5. We cycle the furnace on and off to be sure it is working properly before working on the system.
  6. We cut a 10-inch access hole in the supply and return duct. This hole is used to take before-and-after pictures that we email to you, as well as attach our 10-inch hose that is connected to the gas powered vacuum outside. (These are sealed after cleaning is complete.)

  7. The evaporator coil is protected with a covering.
  8. The filter is removed and a piece of sheet metal blank is inserted to increase suction and prevent debris from passing into the furnace.
  9. The supply registers will be removed and cleaned.
  10. Our flexible rod system with specialized whips is inserted into your vent openings to blast off any dust and debris on the inside of the branch ducts, all the way to the main ducts downstairs.

  11. One-inch holes are drilled into the main duct system so we can insert our flexible rods inside the ducts. Using larger whips (up to 28 inches long) we agitate the main duct until no more dust and debris is left.
  12. The process is repeated for the cold air return ducts.
  13. The evaporator coil cover is removed and the coil is cleaned. The condensate drip pan is cleaned at the same time. (A dirty coil is 20% less efficient).
  14. The blower and blower compartment is cleaned.
  15. The blower door is cleaned and replaced as well as the top furnace door.
  16. The 10 inch holes are covered with a 12 inch sheet metal plate and screwed in place with sheet metal screws. Finally, metal foil tape is placed on the edges of the plate to prevent air loss. (Our goal is to increase the efficiency of your furnace not make it worse with air leaks).
  17. All 1 inch holes are plugged with silver or black air tight plugs.
  18. The sheet metal blank is removed and if available a new filter is replaced in the filter area.
  19. We cycle the furnace on to be sure everything runs properly.
  20. A sticker with our phone number is placed near the filter so you can see when the service was done and when it will be due in the future.
  21. We clean up after ourselves and take up our hoses, tools and tarps and stow them in the truck.
  22. We accept cash, check or VISA, MasterCard or Discover and we thank you for having Duct Works Environmental restore your air duct system so you can really breathe easier with clean ducts.
