What is Duct Cleaning? Duct Cleaning Explained

Are you noticing that your house gets dusty? Even after you’ve dusted the home? Well, that’s most likely because your ducts need cleaning. The way a typical HVAC system works is simplified to this. Your system is composed of an air conditioner which is typically located outside, a furnace that has the ductwork connected to it, and the ductwork itself. The ductwork, which is typically rectangular and/or round metal is divided into two separate systems. The returns and the vents (also called supply vents). The vents force hot/cold air to the living space with the help of the furnaces blower motor. The returns do the opposite, they suck up air from your living space. The air is sucked up, filtered, and redistributed by the vents as either cold or hot air, depending on the temperature you have your system set to. The ductwork is sealed so that air doesn’t escape. This is great for energy efficiency and to make sure that no air is being lost. However, this causes a problem that only duct cleaning can fix. The returns suck up the air but with that air, it also sucks up dust, dirt particles, pollen, pet dander, hair, and other fun stuff. Some of this dust is filtered out but a majority of it just builds up inside the ducts since the ducts are sealed. This is a problem because the air that is distributed to your living space contains all these particles that you are breathing and is causing all the extra dust around your home. 

How does the duct cleaning process work? The process is simple yet effective. We start by hooking up our HP20 vacuum directly to the main supply ductwork in your furnace. The vacuum, which has amazing suction, is gas-powered and stays outside throughout the process. We then start cleaning each supply vent individually. We vacuum, with our industrial shop vacuum, the vent from the inside of your home and then use compressed air to push the rest towards the HP20 vacuum which is located outside. This ensures that the vent is thoroughly clean. We repeat this process for each supply vent. We then disconnect the HP20 Vacuum from the supply ductwork and hook it up to the return ductwork. We repeat the process and clean each return vent individually. We then clean the furnace and sanitize the ductwork. We do this by fogging an EPA-registered disinfectant directly into the return ductwork so that the disinfectant is distributed throughout the duct system. This is especially important in today’s world. We also clean the dryer vent, which is where lint build-up is prevalent. Lint build-up is a fire hazard and affects the overall performance of your dryer. Have you noticed that it is taking extra time to fully dry your clothes? That’s probably because you need to clean your dryer vent. The dryer vent is usually cleaned using a high-spinning brush that is attached to a 30-ft rod. The other end of the rod is a drill that is spinning the brush inside the ductwork and loosening all the lint so that when we pull out the rod the lint comes with it. Finally, we cycle the furnace a few times to make sure that we got all the dust/particles from your system and change the filter.
