HVAC Sizing: Mastering Heat Loss & Heat Gain Calculations

| In Person Training in Portland, OR; No Cost |


Heat pump sizing done right: practical training for HVAC pros.

Overview

Length: 4 Hours

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 the free BetterBuiltNW HVAC Sizing Tool and 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 these specific tools, 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.
