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

Identification of every duct run and system component to be cleaned in San Bruno. Assessment of any physical debris that requires manual removal before vacuum connection in San Bruno, CA.
Before connecting the truck-mounted vacuum, American Air Duct performs gross debris removal from accessible duct sections in San Bruno. Physical construction debris including fasteners, insulation pieces, and larger debris items are manually removed from duct openings in San Bruno, 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 San Bruno.
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 San Bruno, 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 San Bruno.
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 San Bruno. Rotary brush agitation and compressed air tools dislodge construction debris from duct surfaces while the negative pressure captures it in San Bruno, CA. Every duct run in the system is cleaned in San Bruno.
After the duct system is cleaned, accessible air handling unit components are cleaned including the blower assembly, coil section, and cabinet interior in San Bruno, CA. Post-cleaning camera documentation confirms the system has been cleaned in San Bruno. Airflow from supply registers verified before the system is considered ready for use in San Bruno, CA.
