About dL flow tech

In 1982 dL Flow Tech Inc. began with one person, founder Dennis LaVopa. We initially focused on providing quality TAB (Testing Adjusting Balancing) to contractors in the lower Hudson Valley. As time passed, dL Flow Tech grew not only in size but in experience, credibility, and reputation in the competitive HVAC industry. We expanded our business across the Tri-State region by building and maintaining strong relationships with quality contractors and engineers. We also increased the services offered from air and hydronic TAB, to sound measurement, retro commissioning, fire damper testing, duct leakage testing, pipe thickness testing and blower door testing. It has always been the focus of dL Flow Tech to not only maintain technical certifications but to always maintain relationships with clients who appreciate our work ethic. Always stressing the importance of quality, and client service, we have earned a reputation for trustworthy service for over three decades.

While celebrating the past 41 years of service, we look forward to the changes and challenges in the future. Technology advances have led to improvements in safety and comfort within occupied environments. At the same time, the need for tighter environmental controls in public spaces, residences, and especially in mission critical areas such as health-care facilities, keeps increasing. As the industry changes and continues to move forward, we have not forgotten the basic business principles that brought us to where we are today. Credibility, honesty, and attentiveness to our customer’s needs will always be our driving force. dL Flow Tech Co. continues to strive for excellence by maintaining its reputation for hard work and dependability.
