Course Description: (Online / 2:00pm – 4:00pm Pacific Time)

Variable capacity heat pumps aren’t the future anymore. Top contractors have been installing them for years. But the challenges are real: the comfort complaint in February, the humidity problem in July, the electric bill the homeowner didn’t expect. Almost all trace back to a decision made during the design process. This session walks through the mistakes that cause them, and how to catch each one before the equipment is installed, covering the Manual J loads, Total External Static Pressure, and Manual S “advanced” procedures to variable capacity equipment.

Instructor: Eric Fitz – Co-Founder, Amply Energy (maker of ACCA-approved heat pump design software) – and ACCA Manual J Technical Committee Member

Learning Outcomes/Objectives:

• Identify the Manual J input assumptions that most affect the load
• Learn two-minute field checks to verify key Manual J inputs
• Measure total external static pressure to determine whether an existing duct system can support a new heat pump
• Locate design airflow and true capacity in manufacturer extended performance tables
• Apply Manual S advanced procedures to variable capacity equipment
• Evaluate equipment selection trade-offs to choose the right size for the home (e.g., auxiliary heat, low-load cycling, design airflow, and operating cost)

Target Audience:

• HVAC Contractors (Owner Operators)
• HVAC System Designers / Comfort Advisors
• HVAC/R Contractors (Installers / Technicians)
• Home Performance and Electrification Contractors
• Consulting Engineers / Designers
• HVAC/R Instructors
