Professional Air Duct Cleaning

10 Steps to Properly Clean the Air Ducts

 

We are ASCS certified and are proud members of the NADCA and IAQA. DRx DUCT's Patented 10 Step Air Duct Cleaning Process applies Negative Air Pressure to the system. This push/pull cleaning technique is the most effective source removal method currently available and is the ONLY method approved by the EPA and the NADCA. The push/pull concept uses compressed air and physical agitation to break debris free and push it through the ductwork while a powerful vacuum downstream pulls loosened material through and out of the HVAC system.

 

    

1. The supply and return sides of the HVAC system are "zoned" so they can be cleaned separately. This is usually accomplished using zone bags.
2. An access hole is cut into the return side of the HVAC system, the vacuum is connected using a connection collar and the vacuum is turned on.
3. Starting with the farthest register from the vacuum and working back, each return register is removed and cleaned back to the main trunk by snaking down our air compressed whipping agitation tools.  Any rolling dust conditions will be removed with this process.
4. After all the return branches have been cleaned, the main trunks and the plenum drop is cleaned back to the vacuum using our high tech air compressed agitation tools as well.
5. At this point we will now start to work on the supply side of the system. An access hole is cut into the supply side of the HVAC system, the vacuum is connected using a connection collar and the vacuum is turned on.
6.  All supply registers and branches will be cleaned using our special air spickett nozzle tools at each register. All supply registers will be closed off to maximize the negative pressure. At that point, we will then clean one duct at a time using this method. Any etched dust conditions will be removed with this process.
7. After all the supply branches / ducts have been cleaned, the supply main trunks are cleaned back to the vacuum using our high tech air compressed agitation tools
8. After the entire ductwork has been cleaned, the ductwork can then be sanitized or disinfected and the furnace, blower motor, burners, and combustion chamber can then be cleaned.
9. Once the entire cleaning process is completed, all access holes are completely closed using high quality sheet metal sealing off any leaks, making the duct systems easily accessible for repeat cleaning.
