On average, a typical home (1,000 to 3,000 square feet) takes 1.5 to two hours to clean with two professionally trained technicians. This routine process is highly effective in removing the buildup of dust, dirt and harmful contaminants from the home’s duct system, and is performed in a way as to ensure that no dust or debris enters your home. The extraction of these unwanted substances provides better air circulation within your home as well as more efficient furnace operation and, most importantly, healthier air.
Process
Upon arriving at your home, the technician will ensure that the HVAC system is turned off prior to the cleaning.
The procedure starts by connecting an 6-inch vacuum line into the supply section of the duct work near the furnace through the unit’s access panels. Unlike some competitors, Superior Air Duct Cleaning does not charge extra for making access panels.
The system is then sealed using magnetic strips covering all supply and return grills, allowing for concentrated suction.
Once the truck-mounted vacuum is turned on, the system is then put under negative pressure and the cleaning process begins. (Source Removal)
High pressured air (250 psi) is forced through each individual supply vent.
This process is continued until all supply vents are adequately cleaned. The vacuum is then switched to the return section of duct work and the procedure repeated with all return vents.
Following the air washing of all supply and return vents, the technician continues the cleaning in the basement where special tools are inserted into the duct system through a series of 1-inch holes. These tools agitate the dust and direct it towards the vacuum and out of the home.
Both the air conditioning coil and furnace are also cleaned to finalize the cleaning procedure.
All access panels and 1-inch holes are sealed and made air-tight and the system is turned back on to its original settings.
All cleaning procedures follow NADCA regulations.
Sanitization
Within a duct system, the combination of moisture and heat creates an accumulation of bacteria (most often resulting in mold and mildew) which may cause an unpleasant living experience. A sanitizer may be recommended in certain instances where evidence of growth is visible. The sanitizer used is a specially formulated to kill 99.9 percent of all bacteria within the duct system, while being home safe. The solution is applied at the end of the cleaning process using a fogging machine that disperses a powerful mist within your entire duct system. The system is then turned on to allow for the sanitizer to circulate. Contact us for more details!
