Air Duct Cleaning Process - MN Duct Pros
An average air duct cleaning can take around 3-4 hours for a 2,000 sq ft home, up to 8-10 hours for a large, multi system home.
We cut two 8 inch access holes to hook up our negative air machine, one on the supply side above your A coil, and another on the return side near the furnace filter cabinet. We will also need to drill 1 inch holes for access for our whips and tools to properly clean the trunk lines. We seal all holes with either 1" plugs or 28 gauge galvanized steel plates using screws and HVAC duct tape.
System Zoning and Coil Protection:
We split the system into two zones, supply side and return side. We use a piece of rigid foam to protect and cover your A Coil, and a filter block to ensure no air is being pulled through the furnace. Not only does this ensure no contamination of the furnace, it allows us to maximize our suction for the best cleaning efficiency.
We then seal off all of your vents to create a closed system. We do remove all vents in the home for access for our air whips. If the vents are painted on or obstructed we will notify you. The options from here vary, but we are almost always able to clean every vent. We will discuss the options, including cutting around the vent with a razor blade to remove or using a specialized microline, a single whip tool, designed for these applications.
We hook up a 5000+ cfm negative air machine with a hospital grade filter to create a vacuum in your supply ducts. We go vent by vent using 175-200 psi of compressed air with a variety of air tools (microline, single, triple, and octo whips with varying lengths and specific purposes) to agitate, knock loose, and force any contaminants down into your supply trunk lines. We then access the trunk lines and use more compressed air tools to pull all contaminants out of your supply trunk and into our negative air machine. Upon completion of the supply vents and trunks, we repeat the process with all of your return ducts and trunks.
We contact brush vacuum each vent individually during the cleaning. Upon completion, we remove the filter block and foam and vacuum off your air coil, filter tray, and bottom of the furnace. We will also air wash your blower and blower cavity. We do one more pass through the home to vacuum the around all vents and the furnace area, our goal is to leave the home cleaner than when we arrived.
We will do a brief inspection on your furnace, blower, inducer motor, A coil, and drain line and notify you of any concerns. This should not be mistaken for professional HVAC inspections, cleanings, or tune ups. We are not HVAC professionals.
Before and after photos: We include before and after photos from every home we clean. Not only is this a great way to show you what is in your ducts, it helps ensure we are cleaning the system up to our standard of quality. We are usually able to get high quality images in about 90% of the vents.
