All You Need to Know About Duct Cleaning Processes and the Equipment

March 09, 2023

Duct cleaning is a challenging task that requires a lot of skill and the use of specialized equipment such as duct vacuums. The process is much like a regular vacuum cleaning but with more powerful vacuums involved. These vacuums are designed to reach the most inaccessible places which are difficult to clean with a regular appliance. If you would like to learn more about the duct cleaning process and the equipment involved, read on.


What is duct cleaning and what does it involve?


HVAC systems get clogged with dust and debris over time. The purpose of duct cleaning is to remove that dirt and decongest the ductwork for the air to flow freely through it. The primary difference between regular vacuums and specialized duct vacuum cleaners is the suction power - it is much stronger in duct vacuums than in regular vacuum cleaners used in households. Duct vacuums are built to reach hard-to-access places of the HVAC system and effectively remove all the dust and debris that accumulates over time. 


The capacity of suction power is what contractors look for when shopping for a duct cleaning vacuum. Strong suction allows contractors to get all the dirt and dust out of the HVAC system easily. Sometimes, the dirt that wasn't cleaned for years sticks to the inner side of the duct walls, and contractors are required to use specialized brushes to help scrape out the dirt more effectively. This part of the process is usually done before running the vacuum cleaner through the ductwork. 


Whips and skipper balls are used to push dust and debris toward the vacuum system. They release compressed air with significant force, thus pushing the debris toward the ductwork exit. Skipper balls can be forward-blowing and reverse-blowing. The attached tentacles move around the air duct, scraping dirt off the walls of the air duct.
