Why You Should Attend

Today, many homeowners experience problems that HVAC equipment cannot solve. A contractor who understands the “House as a System” approach, has a “leg up” on the competition. Participants in this class leave with a better understanding of how problems can be diagnosed and what they can do to repair them. This class covers a great deal of technical information, but attendees will also learn basic lead generating and lead converting techniques.

This three-day intensive technical class focuses on the problems and opportunities created by duct leakage, poor design and installation. In addition, this class covers other duct system challenges: e.g. high static pressure, low air flow, poor insulation, poor terminal selection, closed door pressure imbalances. The participant will have an understanding of airflow, how to design/size and install a duct system, how too properly use a ductulater for sizing and back engineering and why it is important to have a proper size duct.

All attendees will receive a Comfort Institute Duct Performance Certification by completing and receiving a passing grade on our certification exam. All attendees will also have the option to take the Retrotec DTC exam for an additional $75.
