Duct Diagnostics

Duct Diagnostics is an air duct cleaning company serving homes and businesses across Connecticut since 1998. Its technicians are NADCA-certified and clean residential and commercial HVAC systems using source removal, with mechanical agitation, extraction and HEPA-filtered suction. The company also offers dryer vent cleaning and Aeroseal duct sealing, which seals leaks from the inside of the ductwork.

Duct Diagnostics provides free estimates and a detailed inspection before any work begins, so pricing is set after they have seen the system. Customers in Milford, New Haven, Hartford and Fairfield County are among those it lists as service areas. The company's office is on Bridgeport Avenue in Milford.
