The air duct cleaning process does have many steps and in a home there is often more than one way to complete the task properly. We believe the absolute, most important piece to the air duct cleaning is the technicians performing the work. That is the case with most if not all work done any day any where, you can tell the difference when someone takes pride in their work. This is very important when looking to hire an air duct cleaning company for your home. The EPA’s preferred method of air duct cleaning is known as the push-pull method, which involves attaching a negative air machine to the plenum where all the air comes from before it enters your duct work and eventually into your home. This process we call putting the duct work under negative pressure. The Turbo-jet 4200 is one of the negative air machines we commonly use. The Turbo-jet 4200 is the most powerful negative air machine made by the industries leader in duct cleaning equipment and technology. It has twin motors that run with normal 120 volt power which the machine converts to 220 volt three phase power to run the three phase motors. The twin three phase motors allow for smooth start-ups while not damaging any of the electrical power in the home. These twin motors produce both high static pressure and lots of airflow between 3,000 and 5,000 cubic feet per minute. The Turbo-jet 4200 is large but not to big to fit in most doorways and even in those hard to get to basements where the furnace may be located. It has convenient stair climbers built in that make it easy to get up and down stairs. Combine a well trained and thorough technician with the Turbo-jet 4200 and it’s time for air duct cleaning!
