You have found evidence of rodents in the duct system in Larkspur. 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 Larkspur, CA. You are right that this is more serious than a standard cleaning situation in Larkspur. Rodent contamination in a duct system creates health risks that standard cleaning approaches are not designed to address in Larkspur, 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 Larkspur.
The most serious specific health risk from rodent droppings in a duct system is hantavirus pulmonary syndrome in Larkspur, CA. The virus becomes airborne when droppings are disturbed and dried rodent waste becomes aerosolized in Larkspur. 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 Larkspur, CA. Hantavirus pulmonary syndrome has a fatality rate of approximately 38 percent among confirmed cases in Larkspur. The risk is real and specific and it warrants treatment that accounts for it in Larkspur, CA.

Stop running the HVAC. Call American Air Duct now for same-day scheduling in Larkspur.
Rodent contaminated duct cleaning is not standard duct cleaning in Larkspur. It requires specific safety protocols that protect both the technicians performing the work and the occupants of the home in Larkspur, CA. It requires HEPA filtration equipment that captures the fine particles of dried rodent waste that standard duct cleaning equipment passes through in Larkspur. It requires antimicrobial decontamination treatment applied after thorough physical removal of all waste and nesting material in Larkspur, 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 Larkspur.
Standard duct cleaning agitates duct surfaces and captures the dislodged particles using vacuum equipment in Larkspur. For standard contamination types, this approach is appropriate in Larkspur, 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 Larkspur. The correct approach uses specific containment protocols, technician respiratory protection, and HEPA filtration equipment before any agitation of contaminated surfaces occurs in Larkspur, CA. American Air Duct uses the CDC-recommended wet-down protocol for rodent waste before any mechanical agitation to reduce aerosolization risk in Larkspur.
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 Larkspur. Stop running the HVAC immediately if you have confirmed or strongly suspected rodent contamination in the duct system in Larkspur, CA. Call American Air Duct for same-day scheduling in Larkspur.
Hantavirus pulmonary syndrome is caused by hantaviruses carried primarily by deer mice in Larkspur, 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 Larkspur. A duct system with rodent droppings that runs the HVAC aerosolizes dried waste and distributes it throughout the home in Larkspur, CA. Hantavirus pulmonary syndrome has a significant fatality rate among confirmed cases in Larkspur.
Rodent droppings can carry salmonella and other bacterial pathogens in Larkspur. Other bacterial pathogens associated with rodent waste include leptospira bacteria that cause leptospirosis in Larkspur, CA. Antimicrobial decontamination treatment following thorough physical removal addresses bacterial contamination on the cleaned duct surfaces in Larkspur.
Rodent dander, urine proteins, and droppings are significant allergens for sensitized individuals in Larkspur, CA. The HVAC has been distributing rodent allergen proteins throughout the home with every cycle in Larkspur. Occupants with rodent allergies experience persistent allergic symptoms when the duct system carries rodent allergen contamination in Larkspur, CA.
Rodent activity in duct systems attracts secondary pests in Larkspur. Insects and mites that parasitize rodents can infest the duct system and surrounding areas after the rodents have departed or been exterminated in Larkspur, CA. Complete removal of all rodent waste and nesting material eliminates the food and habitat source for secondary pest infestation in Larkspur.
Rodent droppings at register openings or on duct surfaces when a register is removed are direct confirmation of rodent activity in Larkspur, CA. Mouse droppings are approximately the size and shape of a grain of rice in Larkspur. Both mouse and rat droppings indicate active or recent rodent presence in the duct system in Larkspur, 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 Larkspur. The visible nesting material is the portion accessible at the register opening — the bulk is further in the duct system in Larkspur, 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 Larkspur, CA. Rodents chew to create or enlarge entry points and gather nesting material in Larkspur.
A musky rodent odor from supply registers during HVAC operation indicates active rodent presence or significant rodent waste accumulation in the duct system in Larkspur. A decomposition odor indicates a deceased rodent in the duct system in Larkspur, 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 Larkspur, CA. Air handlers are a common rodent entry point because they provide access to the complete duct network from a single location in Larkspur.
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 Larkspur, CA. American Air Duct uses the CDC-recommended wet-down protocol for rodent waste before any mechanical agitation to reduce aerosolization risk in Larkspur.
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 Larkspur. HEPA filtration captures particles down to 0.3 microns with 99.97 percent efficiency in Larkspur, 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 Larkspur.
Rodent duct decontamination without identifying and sealing the entry points rodents used to access the duct system is a temporary solution in Larkspur. The same entry points that allowed the initial contamination remain available for re-entry in Larkspur, CA. American Air Duct assesses the duct system for entry points during the decontamination service and provides specific recommendations for sealing those points in Larkspur. Sealing the entry points is what makes the decontamination a lasting solution in Larkspur, CA.
