How To Clean Ducts Effectively
All Meyer air duct cleaning systems utilize a push/pull cleaning technique, the most effective source removal method currently available. 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.

- The supply and return sides of the HVAC system are "zoned" so they can be cleaned separately. This is usually accomplished using zone bags, foam blocks or by simply removing the filter from the HVAC system, placing it in a plastic bag and re-installing it.
- 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.
- 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.
- After all the branch runs have been cleaned, the main trunk is cleaned back to the vacuum.
- Once the supply side has been cleaned, an access hole is cut into the return side, the vacuum is attached and the cleaning process is repeated.
In addition to cleaning the interior of the duct, a complete cleaning should include: cleaning the fan, coil and registers, and inspection or replacement of the system's air filter.
