Compressed air tools are essential for all air duct cleaning professionals. These tools, such as blowguns, compressed air whips, and air filters, help them remove persistent debris that is trapped in air ducts. To access the inside of the ducts, technicians use existing openings like supply diffusers, return grilles, or duct covers. In some cases, they may need to make inlet holes in the duct pipes to get in with the cleaning tools.
Depending on the severity of the contamination, they can use rotating brushes, air whips, or compressed air nozzles. Additionally, they can remove a considerable amount of debris by hand brushing and vacuuming by contact. Access tools are also necessary for HVAC technicians to create points of entry into the ducts. These points allow them to inspect and clean the inside of the duct pipes. To create small access points, they usually need a drill with a one-inch drill bit.
For greater access, they can use pneumatic cutters and electric shears. Many tools used to clean air ducts operate pneumatically, so a compressor is a necessary support machine. When it comes to selecting the right equipment for professional duct cleaning, it's important to consider both the pros and cons of each tool. Compressed air whips are often used in ducts that allow more aggressive cleaning techniques to be used. Portable compressors are available for use in workplaces where truck access is limited.
It is very important to choose the right air duct cleaning equipment and receive the right support and training. The potential for success in this industry is high, with low overhead costs and a net profit of 50 to 70 percent. A successful duct cleaning operation usually involves the use of several different types of equipment. These machines are essential to providing the best service to every homeowner. After mechanically cleaning the ducts by shaking and vacuuming them, you can consider using other products.
Associations such as the NADCA have established regulations for cleaning air ducts which helps improve indoor air quality and extend lifespan and improve boiler and air conditioner efficiency.
