Designing an HVAC system with a variable capacity heat pump is no longer a future-forward concept — it’s what top contractors have been doing for years to win more jobs and delight homeowners. But let’s be honest: navigating Manual S, supplemental heat, duct capacity concerns, and utility costs for every project can feel like a minefield. In this session, we’ll cut through the confusion with clear, real-world guidance you can apply to your next project. We’ll cover: • How to apply “advanced” Manual S procedures the right way for variable speed systems • When (and when not) to use strip heat, dual-fuel, or no supplemental at all (and how that relates to duct capacity issues) • Hidden operating cost traps in different regions — and how to avoid them • How targeted envelope or duct improvements can reduce HVAC headaches — and what to prioritize first
We’ll also walk through real-world case studies and show how high-performance heat pump design can be simple, scalable, and profitable — when done right.
Learning Objectives:
By attending this session, attendees will:
Identify the most important construction details and assumptions to focus their verification efforts when performing a Manual J in their climate
Learn how Manual S can be applied correctly for variable capacity heat pumps and how targeted envelope or duct improvements can reduce HVAC headaches — and what to prioritize first
Build confidence in their ability to size and design a heat pump system correctly for their unique climate
