Air Duct Cleaning Training

In-Person Training

Complimentary training is available to customers that purchase NIKRO air duct cleaning equipment. A NIKRO Industries representative will spend one day thoroughly training you and your crew how to operate and maintain your NIKRO equipment and supplies. This training is designed to give you a complete understanding of your new NIKRO equipment and provide practical experience in basic duct cleaning techniques. Training is conducted in our Villa Park, Illinois location.

Ask your NIKRO sales representative for information about training opportunities.

The Air Duct Cleaning Process

The National Air Duct Cleaning Association (NADCA) recognizes the "Source Removal" method as the only acceptable way to properly clean and decontaminate air duct systems. Although duct cleaning is a fairly routine process, it involves knowledge of the duct system and its components.

Conventional air duct systems consist of a supply and a return. The supply ducts of an HVAC system supply heated or cooled air from the air handler to a main "trunk" line. The main trunk line carries the air to smaller "branch" lines which distribute the air to various locations throughout the home.

Although air duct systems vary throughout the country, a typical job will work as follows:

1. Turn the system on to make sure it is operating properly. Once you determine that everything is operating fine, turn the system off.
2. Remove the furnace filter, wrap it in plastic, and reinstall it to separate the supply and return sides of the system.
3. Cut an 8" or 12" access hole into the return trunk line near the HVAC system.
4. Install the duct mounting flange over the access hole and attach the flex duct with a quick connect clamp. The other end of the flex duct will be attached to your NIKRO Portable Air duct Cleaning System. Turn the machine on.
5. Now that the system is running and under negative pressure, go to each register and seal them off with plastic sheets or foam blocks. This will increase air velocity through the system. NOTE: If you are cleaning a large home, the use of more than one zone bag may be necessary to better manage the airflow.
6. Starting from the furthest register from the system, clean each branch line by using duct brushes and compressed air cleaning tools to loosen debris into the main trunk line where it will be vacuumed out by your NIKRO Air Duct Cleaning System. Repeat this process at each register. Once all branch lines have been cleaned, you will clean the main trunk line.
7. Cut an 8" or 12" access hole into the main supply line near the plenum. Inflate a zone bag in the duct between the access hole and the plenum. This ensures a strong vacuum and good negative pressure on the system.
8. Repeat steps 4 through 6 on the supply side of the system.
9. Once the system has been thoroughly cleaned, reseal all access holes with metal patches and reinstall all registers.

NOTE: The preceding information is only a brief overview of the air duct cleaning process. It is not intended to be used for training. Any technician performing air duct cleaning should have a complete understanding of the air handling systems and the air duct cleaning process.
