Our process of cleaning varies depending on your duct system configuration and duct type. No one method can clean all types of ducts and duct configurations. In most cases we use a soft rotating brush, beater brush or high speed fan brush to dislodge the adhered dust and debris from your duct work. Simultaneously our four stage HEPA filtered 4 motor vacuum removes the dust from your duct system.  Other times, we need to use a 5000 CFM negative air system and powerful air whips, pneumatic or mechanical rotating brushes and accessories, to dislodge the dust and debris and our powerful negative air machine removes the dislodged dust and debris  from your ducts. Our third way is to use both methods together. No matter the method that we use, you can be assured we will clean your duct work no matter your duct type or configuration. Our cleaning tools are not limited to 35 feet into your duct work, or limited to 450 RPMs like all other brush driven tools. We can go as far as we need to, 1-1500 RPMs and our vacuum is far more powerful than other rotating brush machines. The optional cleaning of your furnace and evaporator coils, and sanitizing, is highly recommended. Ask about getting your GAS fire place glass and dryer vent cleaned.
