Manual J is evolving—and so is the future of HVAC.

In this episode of the HVAC ADHD™ Vodcast, Jeremy Begley sits down with Wes Davis of the Air Conditioning Contractors of America (ACCA) to discuss one of the most significant updates to HVAC design standards in years.

From Manual J revisions and field survey requirements to APIs, commissioning, and Quality Installation (QI), this conversation explores how better data is reshaping the way HVAC professionals design, install, and verify high-performance systems.

We dive deep into:

• The upcoming Manual J revisions and what contractors need to know
• Why field surveys and accurate data collection matter more than ever
• LIDAR technology, APIs, and the future of HVAC software
• Garbage in, garbage out: why design starts with quality inputs
• ACCA's Quality Installation (QI) initiative and verified performance
• Commissioning, airflow, static pressure, and system verification
• Heat pumps, load calculations, and proper HVAC design
• Why better standards create better contractors—and better customer outcomes

This episode also explores one of the biggest ideas shaping modern HVAC:

👉 The future belongs to contractors who measure, verify, and design with data.
👉 Guesswork is giving way to performance-based HVAC.

Whether you're an HVAC contractor, system designer, energy auditor, building performance professional, commissioning specialist, educator, or technician, this episode delivers practical insights into the standards and technologies that will define the next generation of HVAC.
