Area Inspection and Preparation
Two of our certified technicians will arrive on the job site as scheduled in a decalled truck or a non-decalled truck.
They will fill out an activity sheet – mapping out where all the vents are in the house.
Our certified technicians will use commercial grade equipment
To protect the floor, our technicians will layer drop sheet.
Any pets, children, or toys should be kept away from the work areas, (if possible out of the house)
This is to maximize safety and minimize interruptions to the work process.
All vents are covered with foam blocks(black or grey) or blue paper or closed before starting work to achieve negative air pressure and avoid blowbacks.
Our technicians will begin our work from the furnace room.
This is what your building’s duct system looks like before cleaning.
Our 20,000 CFM vacuum is attached to the building’s main supply and return lines.
Air pressure of 300 PSI will be blown into all return vents, first, to push dirt and debris into main lines for cleaning.
Then the same air pressure of 300 psi will be blown into all the supply vents to push dirt and debris into main lines for cleaning.
Main lines located in the basement are then cleaned with our retractable snake jet system (with air pressure of 300 PSI).
This tool will clean the hard to reach places, including the corners within the line and bring all the loose dirt towards the vacuum working as an air-rake.
All main duct lines are cleaned with a Semi robotic brush which cleans the inner walls of the duct system.
This is repeated 2-5 times as necessary to loosen and agitate dirt and debris towards vacuum.
Main lines are then again cleaned third time with our retractable snake jet system (with air pressure of 300 PSI).
This is what your building’s duct system looks like AFTER cleaning.
All one-inch access points are closed by installing black plugs Eight-inch access holes are covered using stainless sheet metal plate, sealed with aluminum tape.
The work area is cleaned. The furnace and air conditioning unit is inspected to ensure everything is in order.
We will give a Clean Air Certificate.
We will give a report of our progress to the main occupant.
We appreciate your business and we will do whatever it takes to deliver the best service possible.
