Connecticut’s unique climate from humid summers to freezing winters creates a challenging environment for indoor air quality. In late 2024, record wildfire activity across New England significantly increased particulate matter (PM) infiltration in local HVAC systems. At Air Guarden, we’ve seen firsthand how this makes routine maintenance more critical than ever for both your health and fire prevention.
While many companies simply blow compressed air through your vents, our professional Air Duct Cleaning follows the industry-leading NADCA ACR-2021 standard. We use a “Source Removal” methodology that involves:
Negative Pressure: We create a vacuum environment using HEPA-filtered systems that pull up to 13,000 CFM (Cubic Feet per Minute), ensuring no dust escapes into your living rooms.
Mechanical Agitation: Using motorized brushes or specialized “air whips,” we physically dislodge years of accumulated debris from the interior duct walls.
Containment: Every particle of dust, pet dander, and soot is pulled directly into our filtration system, leaving your HVAC system’s “lungs” completely clear.



In Connecticut homes, dust, pet dander, and seasonal pollen naturally accumulate in unconditioned spaces like basements and attics. If left uncleaned, this buildup can lead to microbial growth. To ensure your family breathes clean air, When we do air duct cleaning we follow the NADCA ACR-2021 standard, focusing on a methodology called ‘Source Removal.
If you’ve noticed musty odors or if there was recent water damage, simple cleaning isn’t enough. We offer specialized sanitization to protect your indoor air quality.
EPA-Registered Solutions: We only use treatments that are specifically registered by the EPA for HVAC use, which is a critical safety requirement.
Botanical Options (Benefect Decon 30): For families in Connecticut with pets and children, we prioritize botanical disinfectants derived from thyme oil.
Total Coverage via Fogging: We apply these agents using a “fogging” technique that coats 100% of the internal duct surfaces, killing mold spores and bacteria on contact without requiring a rinse.
Negative Air Pressure: Creating a high-volume environment (up to 13,000 CFM) using HEPA-filtered vacuum systems.
Mechanical Agitation: Using motorized brushes or ‘air whips’ to dislodge debris from interior duct walls.
Extraction: Pulling all contaminants directly into our containment system, ensuring they never enter your living space


When mold or persistent odors are present, we apply antimicrobial treatments. It is a violation of federal law to apply chemicals to ductwork that are not specifically EPA registered for HVAC use.
We prioritize your safety by offering:
Botanical Options (Benefect Decon 30): Derived from thyme oil, these are non toxic, safe for children and pets, and require no rinsing.
Hospital Grade Options: Used for severe mold remediation cases to provide residual protection for up to six months.
