Air Duct Cleaning

Ductwork plays an integral part in delivering cool and heated air as required. Because these systems use forced-air, the contaminants in your house are re-circulated through the ductwork. Without proper maintenance, ducts collect dust and particles over time. If you have a clean duct system, it will help your central air conditioner or furnace run more efficiently and keep everyone in the home breathing easier. Dirty ducts can lead to wasted energy and reduced indoor air quality. To deal with those issues, you will need periodic cleaning of the ducts by a professional.

We start the cleaning process by first inspecting all the returns and vents to ensure readiness for cleaning. We then begin removing duct registers or grills to the entire duct system, which may mean opening up some new access points. Our HVAC technicians use specially manufactured RotoBrush equipment to dislodge dust and debris without damaging the ducts themselves. Our process employs a high-powered vacuum system to remove the dust and particles away. Finally, we sanitize the system to keep the ducts clean going forward and put the whole system back together.

After ducts have been cleaned, most people notice an immediate difference, including a cleaner smell in the air and reduced symptoms for any asthma or allergy sufferers living in the home. Since having your ducts cleaned by a professional, the system will stay clean for several years!
