Construction or renovation is finished in Mill Valley. The contractors are gone. The visible surfaces look clean or nearly clean in Mill Valley, CA. But the duct system is a collector that captured construction contamination throughout the work and is now holding it, waiting for the first time you run the HVAC system in Mill Valley. When you run it, all of it gets distributed to every room in the home in Mill Valley, CA.
Construction debris in a duct system is fundamentally different from the routine dust accumulation that develops over years of normal living in Mill Valley. Drywall dust is one of the most pervasive and problematic construction contaminants. It is fine enough to travel throughout the duct system and settle everywhere in Mill Valley, CA. It is abrasive enough to damage HVAC components when the blower circulates it at speed in Mill Valley. And it is present in quantities after even moderate renovation work that would take years of normal living to accumulate in Mill Valley, CA. Running the HVAC system before cleaning the ducts after construction does not filter out the construction contamination. The filter captures the largest particles and passes the rest through to the blower, the heat exchanger, and the duct system in Mill Valley.
Post construction duct cleaning is not standard duct cleaning performed on a construction site in Mill Valley. It is a different scope, a different debris volume, and a different cleaning approach than routine maintenance cleaning in Mill Valley, CA. The debris types present after construction include materials that require specific handling and are present in volumes that exceed what standard residential cleaning equipment is sized for in Mill Valley. American Air Duct performs post construction duct cleaning as a specific service scaled for the contamination type and volume that construction and renovation work produces in Mill Valley, CA.
Routine duct contamination is fine particulate that accumulates gradually over years of normal HVAC operation in Mill Valley. Post construction contamination is a concentrated deposit of multiple specific debris types that entered the system over a compressed construction period in Mill Valley, CA. Drywall dust that penetrates every duct run throughout the system. Wood dust that settles on every horizontal duct surface in Mill Valley. Insulation fibers that lodge in duct fittings and bends in Mill Valley, CA. Concrete and masonry dust from cutting and grinding. And in some cases physical debris including fasteners and insulation pieces in Mill Valley. The volume and variety of post construction contamination requires an approach scaled for the specific situation in Mill Valley, CA.
A newly constructed home has a duct system that has never been clean in Mill Valley, CA. In many new construction projects, the HVAC system is used for temporary heat or cooling during construction before the home is complete, circulating construction contamination through the system in Mill Valley. A renovated home has a duct system that has been exposed to the specific contamination of the renovation work in Mill Valley, CA. Both situations require cleaning before the system is put into normal occupancy service in Mill Valley.
Generated by every cut, every screw, every sanding pass during interior construction in Mill Valley, CA. One of the finest construction dusts — it travels farther and penetrates further into the duct system than coarser debris in Mill Valley. Settles on every horizontal duct surface. Lodges in every fitting and bend in Mill Valley, CA. When the HVAC runs after construction, it becomes airborne again throughout the system in Mill Valley.
Framing, trim, cabinet, and flooring work generate wood dust that enters the duct system through open registers and the construction atmosphere in Mill Valley. Wood dust is coarser than drywall dust and settles preferentially in horizontal duct sections and at duct fittings in Mill Valley, CA. Heavy sawdust deposits can restrict airflow and create combustible accumulations at points in the duct near heat sources in Mill Valley.
Fiberglass insulation fibers in the duct system are a specific respiratory irritant that becomes airborne when the HVAC distributes them throughout the home in Mill Valley, CA. Blown insulation overspray during attic insulation installation can enter the duct system through duct penetrations and openings in unconditioned spaces in Mill Valley.
Concrete cutting and masonry work generates a very fine, heavy dust that settles throughout the work area and enters any open duct system in the vicinity in Mill Valley. Concrete and masonry dust is alkaline and can affect surfaces and materials it deposits on over time in Mill Valley, CA.
Spray paint and finishing products produce fine aerosol particles that settle on duct surfaces in Mill Valley, CA. These deposits are adherent rather than loose and require mechanical agitation for effective removal in Mill Valley. Oil-based paint residue in the duct system can produce VOC off-gassing that affects indoor air quality at occupancy in Mill Valley, CA.
Open duct registers during construction collect general debris including drywall scraps, wood chips, fasteners, and packaging material in Mill Valley. Metal fasteners are a potential damage hazard for HVAC components in Mill Valley, CA. American Air Duct removes all physical debris from the duct system as part of the gross debris removal phase of every post construction cleaning in Mill Valley.
The first time the HVAC system runs after construction, the blower creates airflow through every duct in the system in Mill Valley, CA. That airflow disturbs the settled construction contamination throughout the duct network and carries it into every room the system serves in Mill Valley. Drywall dust that settled in the duct system during construction becomes airborne in every room with the first HVAC cycle in Mill Valley, CA. The contamination that was contained in the duct system becomes a whole-home air quality problem in Mill Valley.
Drywall dust circulated through the HVAC system at blower speed is mildly abrasive and accumulates on every component it contacts in Mill Valley. On the blower wheel, it builds up on the blades and reduces airflow capacity and throws the wheel out of balance in Mill Valley, CA. On the evaporator coil, it creates a coating that reduces heat transfer efficiency in Mill Valley. On motor windings, it accumulates and contributes to overheating in Mill Valley, CA. Post construction cleaning removes this abrasive contamination before it has been circulated through the components that are most vulnerable to it in Mill Valley.
Post construction duct cleaning is most effective and most impactful when it is performed before the HVAC system is put into service in Mill Valley. Once the system has been run without cleaning, the construction debris has been distributed throughout the system and partially through the components in Mill Valley, CA. Cleaning after the first runs removes the remaining contamination but cannot recover the component surfaces that have already been coated in Mill Valley. Cleaning before first use prevents the contamination from being distributed in the first place in Mill Valley, CA.
A newly constructed home has a duct system that has never been in clean operating condition in Mill Valley, CA. In many new construction projects, the HVAC system is operated for temporary climate control during construction, actively distributing construction contamination throughout the system in Mill Valley. New construction cleaning covers the complete system from air handler to every supply register and return grille in Mill Valley, CA.
Cabinet removal and installation generates wood dust. Tile cutting generates fine concrete and tile dust. The supply and return vents in the renovated room and adjacent rooms connected to the same duct runs are the primary accumulation points in Mill Valley. American Air Duct cleans the full system to address contamination in both the renovation area and connected duct runs in Mill Valley, CA.
A whole-home renovation exposes the entire duct system to construction contamination throughout the work period in Mill Valley, CA. Contamination is distributed throughout every duct run in higher concentrations than single-room renovation work produces in Mill Valley. Requires the same complete system approach as new construction cleaning in Mill Valley, CA.
Home additions connect new duct work to the existing system in Mill Valley. The new duct sections contain installation debris. The connection to the existing system allows construction contamination from the addition work to enter the existing duct network in Mill Valley, CA. Post construction cleaning covers both the new sections and the existing system they connect to in Mill Valley.
Commercial construction and tenant fit-out projects generate the same duct contamination types as residential work but at larger scale in Mill Valley, CA. American Air Duct provides commercial post construction duct cleaning scaled for the specific building size and project scope in Mill Valley.
Before first use — not after the first run distributes everything to every room in Mill Valley.

Identification of every duct run and system component to be cleaned in Mill Valley. Assessment of any physical debris that requires manual removal before vacuum connection in Mill Valley, CA.
Before connecting the truck-mounted vacuum, American Air Duct performs gross debris removal from accessible duct sections in Mill Valley. Physical construction debris including fasteners, insulation pieces, and larger debris items are manually removed from duct openings in Mill Valley, CA. Gross debris removal before vacuum connection prevents large debris from entering the vacuum system and prevents the vacuum from pushing large debris further into the duct network in Mill Valley.
With gross debris removed, American Air Duct connects the truck-mounted vacuum to the duct system and establishes sustained negative pressure throughout the complete system in Mill Valley, CA. The high-capacity equipment used for post construction cleaning creates the sustained negative pressure needed to capture the higher debris volume that construction contamination represents in Mill Valley.
With negative pressure established, our technicians systematically clean every supply duct run from the trunk line to each register opening and every return duct run from each grille to the air handling unit in Mill Valley. Rotary brush agitation and compressed air tools dislodge construction debris from duct surfaces while the negative pressure captures it in Mill Valley, CA. Every duct run in the system is cleaned in Mill Valley.
After the duct system is cleaned, accessible air handling unit components are cleaned including the blower assembly, coil section, and cabinet interior in Mill Valley, CA. Post-cleaning camera documentation confirms the system has been cleaned in Mill Valley. Airflow from supply registers verified before the system is considered ready for use in Mill Valley, CA.
