You have found evidence of rodents in the duct system in Colma. Droppings at a register opening. Nesting material visible in a duct when you removed a grille. A persistent rodent odor from the vents when the HVAC runs in Colma, CA. You are right that this is more serious than a standard cleaning situation in Colma. Rodent contamination in a duct system creates health risks that standard cleaning approaches are not designed to address in Colma, CA. The contamination includes biological waste that carries specific pathogens. The HVAC system has been distributing those pathogens to every room in the home with every cycle in Colma.
The most serious specific health risk from rodent droppings in a duct system is hantavirus pulmonary syndrome in Colma, CA. The virus becomes airborne when droppings are disturbed and dried rodent waste becomes aerosolized in Colma. A HVAC system with rodent contaminated ducts that runs without the ducts being decontaminated is aerosolizing dried rodent waste and distributing it to every room in the home in Colma, CA. Hantavirus pulmonary syndrome has a fatality rate of approximately 38 percent among confirmed cases in Colma. The risk is real and specific and it warrants treatment that accounts for it in Colma, CA.
American Air Duct performs rodent contaminated duct cleaning throughout Colma with the correct safety protocols, correct equipment, and the complete decontamination scope that rodent contamination requires in Colma, CA. Stop running the HVAC. Call American Air Duct now for same-day scheduling in Colma.
Rodent contaminated duct cleaning is not standard duct cleaning in Colma. It requires specific safety protocols that protect both the technicians performing the work and the occupants of the home in Colma, CA. It requires HEPA filtration equipment that captures the fine particles of dried rodent waste that standard duct cleaning equipment passes through in Colma. It requires antimicrobial decontamination treatment applied after thorough physical removal of all waste and nesting material in Colma, CA. And it requires assessment of the entry points rodents used to access the duct system so those points can be sealed against future intrusion in Colma.
Standard duct cleaning agitates duct surfaces and captures the dislodged particles using vacuum equipment in Colma. For standard contamination types, this approach is appropriate in Colma, CA. For rodent contamination, the agitation step creates a specific risk because dried rodent waste aerosolized during agitation can carry hantavirus and other pathogens in Colma. The correct approach uses specific containment protocols, technician respiratory protection, and HEPA filtration equipment before any agitation of contaminated surfaces occurs in Colma, CA. American Air Duct uses the CDC-recommended wet-down protocol for rodent waste before any mechanical agitation to reduce aerosolization risk in Colma.
Running the HVAC system with rodent contaminated ducts distributes dried rodent waste particles and the pathogens they may carry to every room in the home with every cycle in Colma. Stop running the HVAC immediately if you have confirmed or strongly suspected rodent contamination in the duct system in Colma, CA. Call American Air Duct for same-day scheduling in Colma.
Hantavirus pulmonary syndrome is caused by hantaviruses carried primarily by deer mice in Colma, CA. The virus is shed in droppings, urine, and saliva. Human infection occurs primarily through inhalation of aerosolized viral particles from disturbed dried rodent waste in Colma. A duct system with rodent droppings that runs the HVAC aerosolizes dried waste and distributes it throughout the home in Colma, CA. Hantavirus pulmonary syndrome has a significant fatality rate among confirmed cases in Colma.
Rodent droppings can carry salmonella and other bacterial pathogens in Colma. Other bacterial pathogens associated with rodent waste include leptospira bacteria that cause leptospirosis in Colma, CA. Antimicrobial decontamination treatment following thorough physical removal addresses bacterial contamination on the cleaned duct surfaces in Colma.
Rodent dander, urine proteins, and droppings are significant allergens for sensitized individuals in Colma, CA. The HVAC has been distributing rodent allergen proteins throughout the home with every cycle in Colma. Occupants with rodent allergies experience persistent allergic symptoms when the duct system carries rodent allergen contamination in Colma, CA.
Rodent activity in duct systems attracts secondary pests in Colma. Insects and mites that parasitize rodents can infest the duct system and surrounding areas after the rodents have departed or been exterminated in Colma, CA. Complete removal of all rodent waste and nesting material eliminates the food and habitat source for secondary pest infestation in Colma.
Rodent droppings at register openings or on duct surfaces when a register is removed are direct confirmation of rodent activity in Colma, CA. Mouse droppings are approximately the size and shape of a grain of rice in Colma. Both mouse and rat droppings indicate active or recent rodent presence in the duct system in Colma, CA.
Nesting material including insulation fibers, paper, fabric, and plant material at register openings indicates active or recent rodent nesting in the duct system in Colma. The visible nesting material is the portion accessible at the register opening — the bulk is further in the duct system in Colma, CA.
Gnaw marks on flexible ductwork, on duct insulation in attics or crawl spaces, or on plastic duct components indicate rodent activity in or near the duct system in Colma, CA. Rodents chew to create or enlarge entry points and gather nesting material in Colma.
A musky rodent odor from supply registers during HVAC operation indicates active rodent presence or significant rodent waste accumulation in the duct system in Colma. A decomposition odor indicates a deceased rodent in the duct system in Colma, CA.
Droppings, gnaw marks, or nesting material near the air handler cabinet indicate that rodents have accessed or are attempting to access the HVAC system at the air handler in Colma, CA. Air handlers are a common rodent entry point because they provide access to the complete duct network from a single location in Colma.
Without appropriate respiratory protection for the technicians and containment of the work area, the agitation step in standard cleaning creates exposure risk for everyone in and near the home in Colma, CA. American Air Duct uses the CDC-recommended wet-down protocol for rodent waste before any mechanical agitation to reduce aerosolization risk in Colma.
The filtration in standard duct cleaning equipment may not capture the finest particles of dried rodent waste including the viral and bacterial particles associated with hantavirus and other pathogens in Colma. HEPA filtration captures particles down to 0.3 microns with 99.97 percent efficiency in Colma, CA. HEPA-equipped vacuum equipment is the appropriate standard for rodent contamination work because it captures the particle sizes associated with the relevant health risks in Colma.
Rodent duct decontamination without identifying and sealing the entry points rodents used to access the duct system is a temporary solution in Colma. The same entry points that allowed the initial contamination remain available for re-entry in Colma, CA. American Air Duct assesses the duct system for entry points during the decontamination service and provides specific recommendations for sealing those points in Colma. Sealing the entry points is what makes the decontamination a lasting solution in Colma, CA.

HEPA-equipped vacuum equipment is connected to the duct system in Colma.
Rodent droppings and nesting material are treated with an EPA-registered disinfectant spray before any physical disturbance in Colma, CA. The wet-down step reduces aerosolization of dried waste particles during the physical removal process in Colma. After the disinfectant contact time has been met, physical removal of all treated waste and nesting material proceeds in Colma, CA. All removed material is sealed in appropriate disposal containers in Colma.
After gross waste removal, HEPA-equipped vacuum equipment is used to clean all contaminated duct surfaces throughout the affected sections in Colma. The HEPA filtration captures the fine particles of residual dried waste including the particle sizes associated with hantavirus and other pathogens in Colma, CA.
