Indoor air quality directly impacts the health, safety, and comfort of everyone who enters your building. Over time, ducts collect dust, dander, chemicals, and other contaminants that can worsen allergies, aggravate respiratory conditions, and create long-term health risks.

Duct Diagnostics provides expert duct cleaning services for a wide range of commercial facilities. We are trusted by hospitals, schools and colleges, museums and galleries, aquariums, military facilities, churches, laboratories, clean rooms, and office buildings across Connecticut. Each of these environments requires a different level of care, and our highly trained team understands how to deliver precise, effective results every time.

Our technicians are OSHA-10 certified and follow strict environmental controls to ensure debris never escapes into the air during the cleaning process. As a registered SBE, we are also recognized for meeting the highest standards of safety and compliance. When businesses and institutions need reliable duct cleaning, they turn to us for cleaner air and healthier spaces.
