The Energy Conservatory (TEC)

TEC continues to set the standard for specialized air flow and pressure measuring devices used to monitor and analyze the complex interactions which determine building performance. Innovative design and careful engineering have given TEC a reputation for designing the most reliable, accurate and respected line of performance testing products on the market today. TEC was in the forefront of research that led to the understanding that duct leakage is a big problem–not just for energy waste, but also because pressure imbalances caused by the duct system can result in back-drafting and indoor air quality problems. This realization led to the development of the Minneapolis Duct Blaster® system, the most widely used duct leakage testing system in the world.
