Mastering Heat Loss & Heat Gain Calculations

Selecting the right heat pump starts with accurate heat loss and heat gain calculations — a critical step in ensuring energy efficiency, comfort, and system longevity.

This interactive in-person training will equip HVAC professionals, raters, and contractors with the essential skills to properly size equipment for diverse building conditions. We’ll provide hands-on practice, guiding participants through real-world load calculations using HVAC ST software that is based on Manual J calculations. Attendees will input data, analyze results, and refine calculations to ensure proficiency in accurate heat loss and heat gain assessments.

While the class will use the HVAC ST tool, the information learned through this process will inform the accuracy of heat loss & heat gain calculations regardless of the software individual contractors may use in their businesses.

Participants will explore best practices, common pitfalls, and real-world scenarios to avoid costly oversizing/undersizing mistakes. Whether you’re new to load calculations or looking to refine your approach, this course provides the technical knowledge and practical application needed to make informed, data-driven decisions.
