That led to the birth of National Comfort Institute. It also led to the establishment of what is known today as the High-Performance HVAC Industry.

His influence remains in managing the only organization that trains and certifies HVAC technicians and contractors in the science and art of High-Performance Contracting™.

But it doesn’t stop there. He also works with distributors, manufacturers, public utility organizations, and HVAC trade associations. His efforts focuson furthering the need for testing, diagnosing, and resolving airflow issues throughout the HVAC system.
