The answer to 'types of duct cleaning' is that there are several methods used to clean HVAC ductwork in homes. The most common types of duct cleaning include:
Vacuum-based duct cleaning: This is the most widely used method, where a powerful vacuum system is used to suction out dirt, dust, and debris from the ductwork. The vacuum is attached to the ductwork openings, and specialized brushes or agitation tools are used to dislodge and remove contaminants.
Rotary brush duct cleaning: This method uses a motorized, rotating brush that is inserted into the ductwork to scrub the interior surfaces and dislodge built-up debris. The debris is then vacuumed out of the system.
Air whip duct cleaning: This technique uses high-pressure air to blast contaminants out of the ductwork. Air whips or compressed air tools are inserted into the ducts to dislodge and propel debris out of the system.
