DUCTZ of the Upper Bay Region
DUCTZ does complete HVAC and ventilation systems cleaning and restoration, including:
- Clean every air duct from the boot to the trunk (both supply and return) (some others only clean as far as their equipment can reach)
- Clean each vent cover/register
- Clean both the supply and return trunk lines (and any panned returns)
- Clean the accessible evaporator coil, drain, drain pan, and plenum
- Clean the blower and blower motor (sometimes requires removal of the assembly for proper cleaning and re-installation)
- Clean the air handler cabinet
- Install a new pleated filter (optional) of at least a Merv 8 rating.
You should expect a typical system to take 4 to 7 hours to complete.

Air Duct Cleaning Process
Is there a difference between duct cleaners?
There is a ton of difference between NADCA (National Air Duct Cleaners Association) certified firms, and those who are not. NADCA-certified companies have received training in properly cleaning your air ducts, and deploy the source removal method under negative air pressure. A much better method than those who simply blow and go, or use a brush attached to a shop vac-like device (though it does take longer and perhaps costs more), it is the right method to clean your ducts if you want contaminants and allergens removed from the system.
That said, even among those certified, there are differences:
- Many duct cleaners use compressed air with whips and "skipper balls" inserted into the duct to push debris toward the negative air source (a very large vacuum system attached to your main trunk lines).
- DUCTZ of the Upper Bay Region also uses cable-driven brushes to contact all duct surfaces fully. There is a huge benefit to cleaning all the surfaces vs. just where the whip contacted it. (see photos). It does take longer, but if the reason you had the ducts cleaned is for allergy and asthma symptoms, we believe they must be brushed to get the most benefit.
- DUCTZ uses the source removal brush technique, which utilizes cable-driven brushes combined with compressed air tools, whips, and skipper balls while under negative air pressure. Our process is much more thorough than compressed air alone.
As a brief overview, our process involves any number of 127 identifiable and distinct tasks. It demands an array of tools, machinery, and supplies. And it includes our exclusive patented process, which involves the application of a metallic barrier in the air handler, eliminating fiberglass shedding and preventing the fiberglass from acting like an absorbent sponge, which collects dirt and moisture and creates a breeding ground for mold, bacteria, and fungi.
- Dryer Vent Cleaning (we offer a discount when completed at the time of a duct cleaning)
- Type-2 (wet or chemical) cleaning of blowers and coils
- UV-C germicidal lighting installation
- Deodorizing (especially for smoke damage, nicotine smell, dead critters, etc.)
- Applications of Biostat products to prevent mold re-growth (only when required)
Our technicians are trained in the complete step-by-step process, gaining a full understanding of how we clean to this high standard and why.
- Removing and Washing all registers or vents
- Cleaning of all accessible ductwork from the register to the trunk
- Cleaning both the supply and return air trunks, as well as the return pans (I am always surprised that many duct cleaners forget them)
- Cleaning accessible evaporator coil and plenum inside the air handler
- Clean accessible Blower Wheel and motor
- Clean Air Handler cabinet
- Remove all trash and debris collected from ducts
- Seal all access ports to assure no leakage
- installation of a premium pleated filter (optional)
