How It Works: Our exclusive Rotobrush machine brushes and vacuums at the same time.  The process loosens build-up inside the air ducts then quickly vacuums the dust up before it has a chance to reattach to the side of the duct. The powerful yet flexible Rotobrush easily cleans all types of air duct construction including right angle turns. Every duct is cleaned from each register to the furnace, removing contaminates that circulate throughout the duct system and into your home. The plenum is accessed, cleaned and resealed. Every register cover is cleaned and sanitized to remove cooking oil film, nicotine film and other dust collecting substances. All air ducts and vents are sanitized with an environmentally safe sanitizer commonly used in hospitals and nursing homes. Finally, the furnace and air handler are vacuumed at no additional charge. We offer quality and value, and stand behind our work 100%.         Benefits: Eliminates harmful organisms such as dust mites, mildew, pollen and animal dander which cause allergic reactions. Increases the efficiency of the HVAC system and reduces operating expenses.           Recommendations: For a clean and healthy home, and to keep your HVAC system operating efficiently, duct cleaning is recommended every three to five years.
