As proud members of the NADCA and IAQA, our unique ten step duct cleaning process applies negative air pressure source removal when cleaning the HVAC conveyance unit and air duct systems. This duct cleaning process is the BEST and also an effective source removal technique that is currently accessible. Using a method called push/pull, this approach uses a powerful vacuum and compressed air physical agitation tools To break up any debris and propel it through the ductwork while a very powerful vacuum removes loose material out of the HVAC system. Our certified technicians practice furnace and air duct cleaning in accordance with NADCA Guidelines and Code of Ethics. To break up any debris and propel it through the ductwork while a very powerful vacuum removes loose material out of the HVAC system.
The Duct Cleaning Process
The HVAC air duct systems’ supply and return side will be “zoned” so our technicians can clean them separately. This can be achieved with the use of zone bags.
- To access the supply side, the supply line will have a hole cut into it; we then connect the vacuum with the use of the connection collar, with the vacuum being turned on outside.
- 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: All supply ducts will be cleaned using our viper whip system where we snake down 20 plus ft inside every vent. This will disturb and dislodge any dust and debris that is on the main trunk lines.
- Once all of the supply branches are clean, the primary trunk, as well as plenum drop, will be cleaned by the vacuum with the use of high-pressure air compressed agitation air whipping tools.
- After the systems’ supply side has been completely cleaned, we will then work on the system’s return side. We will repeat the same step as the supply line and cut an access hole. The vacuum is then connected using the connection collar and will then be turned on.
- All return ducts will be cleaned using our viper whip system where we snake down 20 plus ft inside every vent. This will disturb and dislodge all dust and debris into the main trunk lines.
- After all ductwork, including the main trunk lines, have been cleaned, the ductwork will then be sterilized or sanitized.
- We then air wash cleaned the furnace, squirrel cage, and blower motor.
- When the entire air duct system has been completely cleaned, the access holes will then be closed up with the use of high-quality sheet metal that can seal off any leaks, making it easier to access the duct system for future cleanings.
- A final walk through is performed ensuring everything is clean before leaving.
