Outdoor Temperature limiting your ability to commission a heat pump? Many technicians rely on heating-mode operation to charge a heat pump—but that only provides a rough estimate. The final refrigerant charge must always be verified in cooling mode to achieve true peak performance. This session dispels common myths, explains why cooling-mode charging is non-negotiable, and shows how it ensures system efficiency, reliability, and occupant comfort.
We’ll reference manufacturer guidelines and ACCA standards to demonstrate that verifying the charge in cooling mode is the industry-standard approach. Gustimating the line length and charge still requires verification.
Attendees will leave with practical options and the confidence to accurately commission heat pumps every time.
