History of T&D Duct Cleaning

With over 20 years of HVAC experience and a strong desire to serve the community, Tim Unverzagt and Dave Schneider founded T&D Duct Cleaning in 2002. The idea had been with Dave since family members started having severe allergy attacks in the mid 1990's. After doing research into how to reduce the cumulative effects airborne allergens, he tried various active air filters with mixed results. Then he read an article on Air Duct Cleaning by Louise H. Bethea, M.D., P.A. Board Certified Allergist/Immunologist. That's when Tim and Dave formed T&D Duct Cleaning and started cleaning air duct systems in the Baltimore/Metro area.
