Duct cleaning is a step by step process that starts by hooking up a large and powerful vacuum to your furnace. This requires a small hole in your venting that will pull all the dust and debris down through your vents. If you have had duct cleaning completed in the past, likely, the hole in your venting will be reused. Once this stage is complete, vents that are not being cleaned will be blocked off to create the most suction power in the vent that is being cleaned. From there a powerful high pressure hose, known as a snake is fed through your vents to break up debris and dust down towards the vacuum. This process is repeated until all vents are cleaned including your cold air return and dryer vents. If you have multiple furnaces, the process will be replicated with your second furnace.
