Duct cleaning is a service that uses specialized blowers, vacuums, and brushes to clean out the supply, intake, and return ducts throughout your home. Duct cleaning should also involve a thorough cleaning of the air handler, registers, grilles, fans, motors, housings, and coils of the HVAC system.
How it works
Cleaning the air handler
The air handler is the unit responsible for the blowing the air throughout your home. It is considered the heart of the air system. All the air in your home goes through this unit so it must be cleaned. If it is not cleaned and decontaminated, all air coming through here will be contaminated even if your ducts were clean.
Clean Vent Registers
Vent registers are the grills attached to your air duct openings. These should be cleaned as well since this is the last part of the duct that the air touches before it enters your home or living place.
Clean and Decontaminate Air Ducts
In this process, the inside of your air ducts will actually be cleaned and decontaminated. There are actually two ways to clean air ducts that both involve high powered air duct cleaning equipment. One is called negative air cleaning or push-pull cleaning and the other is contact cleaning. Either way is 100% effective. Ask your technician about the details.
Applying Deodorizer and Soot Sealer
This is the last step in air duct cleaning. It involves applying 1 or more cleaning solution into the air duct to deodorize it and lock any fine particulates that may be trapped. This is the final step that will help you remove any minor lingering odors and give your system a fresh clean smell.
