19 STEP CLEANING PROCESS

  1. The complete HVAC unit/system is turned off.

  2. The furnace cover(s) and air filter(s) are removed. The furnace, blower motor, and air filter(s) are then inspected for cleanliness. If necessary, the service technician will recommend whether these components should be cleaned or not and the services will be offered. If the air filter(s) needs to be replaced the filter size will be measured and noted and may be purchased at the customers' discretion. Efficient, high-quality filtration is key to maintaining your HVAC equipment and keeping your duct system clean.

  3. The technician then examines the house and the main ductwork in the basement to determine how many zones there are. The zones for residencies are broken down as follows: single, double, or triple zone.

  4. An access hole 6 inches in diameter is cut into each supply plenum (depending on how many zones) and into the cold air return. The technician will choose where to cut these access holes according to experience and convenience/accessibility to the structure of the ductwork for that specific job.

  5. Excluding one, all supply vent covers/registers are closed which increases the air movement in the ducts. The one open supply register allows the air to safely flow backward through the air duct system without creating adverse negative pressure.
  6. All return covers are prepared for removal.

  7. First, the vacuum hose is connected to the return access hole.

  8. The Super-Vac Truck-mounted system is then turned on to create negative pressure within the return ductwork.

  9. Using forward and reverse air blast assemblies, all return registers, branches, and main return ducts are air-washed and cleaned. Agitation is a method used which causes dust and debris to be quickly caught up in the air movement and is vacuumed out of the system into the vast holding tank mounted to the truck.

  10. The vacuum hose is then situated where the return duct meets the furnace to ensure any dust/debris that has fallen hasn't been missed and everything is collected.

  11. The vacuum hose is then connected to the access hole(s) made in the supply plenum(s) creating negative pressure within the supply ductwork.

  12. Starting from the vent opening furthest away from the furnace, each branch line is air-washed and cleaned using only forward air blast assemblies. This process is then repeated at each supply vent opening as the technician makes his way from the top floor down to the bottom floor/basement. Each register will be opened and then closed again once cleaned.

  13. Once all supply branch lines are cleaned, the technician will cut one-inch holes every couple of feet in the main supply ductwork that is exposed to the eye. Using forward and
    reverse air blast assemblies, the main supply ductwork is then air-washed and cleaned to ensure all dust/debris has been removed and collected out of the whole duct system.

  14. If any other services are requested (i.e. Furnace cleaning, blower & coil cleaning, etc.) they will be done in-between cleaning the return and the supply or after the
    complete duct system has been cleaned

  15. The Super-Vac Truck-mounted system is then turned off.

  16. All supply vent covers/registers are opened.

  17. The HVAC unit/system is then turned on and inspected for proper airflow.

  18. If the customer has requested sanitization, a product called Benefect is sprayed/fogged throughout the air duct system using the access holes that were made. A combination between air pressure and the hot air supply now flowing pushes the sanitizer throughout the whole air duct system. This product is a disinfectant and a fungicide and immediately kills any bacteria, mold/mildew, fungal spores, and other contaminants that may be left in the system. This product will air-dry and evaporate leaving no chemical residuals.

  19. All one-inch holes are plugged and sealed with soft-plastic plugs standard to the duct cleaning industry. All access holes are then securely closed with proper gauge
    sheet metal plates cut to size. Each metal plate is secured to the duct using sheet metal screws and the edges are sealed with aluminum foil tape ensuring a complete, proper seal.
