Homeowners worried about allergy triggers and other irritants circulating throughout their duct work often engage a professional solution for the buildup inside their ducts. A thorough, precise cleaning given by a qualified and well-trained professional should bring about an observable decrease of dust and other particulate matter in your ventilation work.
A duct cleaning is particularly necessary if your ducts contain pests, mold or an amount of dust and debris so excessive that it is actually obstructing airflow. Such instances often occur after major renovations. In these cases, you should certainly schedule a professional inspection and cleaning. To be safe, always schedule a professional inspection and cleaning after major renovation work.
Home renovations are, of course, not the only factors that can significantly impact airflow. Pet hair, cigarette smoke, and water damage will all cause more rapid buildup of particulates. The condition of the duct work and the cleanliness of the air inside your home is of particular importance when a family member or frequent visitor suffers from allergies or asthma.
Duct cleaning contractors use large, portable or truck-mounted vacuum collection devices to remove dust and debris from your duct work. However, technicians must perform a few preliminary steps before the vacuuming and cleaning begins. They must first connect the vacuum’s hose to the main trunk lines of duct work attached to the air handler. The technician will cut an access hole in the duct, connect the vacuum hose, and seal the area as an access point when the job is complete.
Every HVAC system includes a supply side and a return side. These two sides are separate and the cleaning process must be performed on each.
Even the most powerful vacuum will fail to effectively clean your ducts if each register in the house is uncovered, so the technician should seal those with foam blocks or by closing the covers. Turning on the vacuum will now create negative pressure inside the duct work, and particles inside will be sucked into the collection device as they’re brushed or blown loose.
Once the system is under negative pressure, each register should be uncovered and cleaned one by one. Technicians will use brushes or compressed air tools, in addition to simple vacuums, to dislodge dust and send it down the duct work to the vacuum collection device. Once the work is complete, the technicians will seal the hole cut into the duct work.
