2026-03-24 09:00 - 10:30 (America/Los_Angeles)
Zone control is a popular strategy for addressing different climate zones in a home. Many customers and contractors newer to heat pumps are drawn to multi-split systems that utilize a single outdoor unit to run multiple air handlers, but there can be unintended comfort sacrifices if not done carefully. In this webinar we will focus on various approaches to zone control for efficient and comfortable outcomes. We will compare traditional zoning with zone control, multi-split systems, multiple one-to-one systems, and combinations of these solutions.
Agenda:

Introduction and safety message
Electrify Efficiently
Zone control strategies
Avoiding comfort sacrifices with zone control
Different approaches for zone control to achieve efficient, comfortable outcomes

The objective of this course is that at the conclusion, participants will be able to:

Summarize operational differences between single-stage, two-stage and inverter heat pumps
Name one downside of installing a single multi-split outdoor unit instead of multiple outdoor units
Explain why many mini split brands do not work well with traditional zone control
Describe one scenario where installing a multi-split unit makes sense
