Professional Air Duct Cleaning

We are ASCS certified and are proud members of the NADCA and IAQA. DRx DUCT's Patented 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. Each vent cover is carefully removed and vacuumed cleaned.
4. Starting with the farthest branch from the vacuum and working toward the closest, each branch is individually cleaned back to the main trunk using a combination of compressed air and physical agitation tools.
5. After all the branch runs have been cleaned, the main trunk is cleaned back to the vacuum.
6. Once the return side has been cleaned, the supply side will then be cleaned.

7. After the entire ductwork has been cleaned, the ductwork can then be sanitized and the furnace can be air washed if applicable.  

8. Once the entire cleaning process is completed, all access holes are completely closed and insulated sealing off any leaks, making the duct systems easily accessible for repeat cleaning.
