Подробнее о видео

In this HVAC School video, instructor Bert continues his training for the Kalos team on preparing heat pumps for heating season. Picking up where Bryan Orr left off in part 1, Bert reviews auxiliary heat, heat strip wire and breaker sizing, and interlock relays.

He then dives deeper into testing heat pumps when it's cold outside - checking charge, what to look for in terms of frost and ice buildup, abnormal signs, and more. Bert shares manufacturer charging charts, rules of thumb for pressures, and how to accurately check charge using a charging jacket. Additional topics include:

Normal coil frost vs ice-bound coils
Defrost cycle
Cooling and heating cycles
Reversing valve function
Checking the charge in heat mode
Accurately reading discharge temperatures
Approach method
Temperature split

As always, Bert peppers the lesson with real-world stories and examples from the field to drive home key points. The video strikes a perfect balance between technical knowledge and practical application. Whether you're a seasoned pro or just getting started in HVAC, you'll learn valuable skills from one of the industry's most engaging teachers.
