Overview of the Cleaning Process

HVAC system cleaning projects require a game plan. Project length can vary from a few hours to six months or more. The size and scope of the project are the two key elements that will have an impact on the length of time necessary for completion. The entire duct cleaning project will run smoothest when an in-depth review is first conducted to determine the expectations and desired outcome for both the customer and duct cleaning company.

  • During cleaning, the entire HVAC system is placed under continuous negative pressure — with a vacuum — to prevent the spread of contaminants.
  • Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning.
  • This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.
