    About the Instructors

    Russell Prach

    Russell Prach, son of Ellis, has grown up in this industry. Shadowing his father, Russell has acquired Ellis’ expertise on heat exchanger services, and is eager to pass it along. Russell’s passion and enthusiasm for this trade is contagious; you will see his enthusiasm transpire in his teaching methods as he captures the attention of each and every student or attendee.

    Thanks to Russell's passion, both contractors, and home inspectors alike, leave the class inspired and excited to use their newfound knowledge in the field.

    Christopher Prach

    Meet the youngest instructor on our team, Christopher Prach. Although new to the training, Christopher grew up in this industry under Ellis, so heat exchanger training and servicing are both very familiar to him.

    The knowledge he brings from his extensive field experience, accompanied by the expertise passed down from his father, Christopher makes a great addition to the instructing team. When Christopher is not on tour, aside from being a father, he oversees the field operations in our service company.
