Air duct cleaning is happening every day in neighborhoods all over Portland and Vancouver. This short story should help with what to expect when scheduling your duct cleaning service. The vent cleaning in an 1800-2200 sq ft home takes two technicians three to four hours, it can be done by one tech but it would take longer. Using a Hepa filtered negative air machine is the EPA’s preferred method for duct cleaning. After separating each side of the HVAC system and attaching the negative air machine to one side either supply or return, the techs should then seal every vent in the home and starting with the duct as far away from the system as possible navigate air whips from each register in the home all the way back to the furnace. The rest of the work is done in and around the furnace itself and back from the return and supply plenums. The right duct cleaning companies will show you each step of the process and should be able to show you what comes from the ductwork and they should never add fees to the the original service. This said, there are no $99 or funnier yet $59 whole house duct cleaning specials, this is impossible for a company to maintain, there is just too much work involved in a full service. There are resources available to research the guys you can trust. You may check Angie’s List if you’re a member, if not, there is the Better Business Bureau or reviews on Yelp and Google+! The service is awesome and should be done once every 3-5 years. Good luck to all!

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!
