### Beyond the Box: HVAC Starts with the House

Tuesday, November 11 | 12:00 - 1:00 PM ET

An ACCA Codes and Coffee webinar

---

You can’t HVACR your way out of a bad house. Too often, contractors are called in to fix comfort, humidity, or efficiency problems that aren’t caused by the equipment at all — they’re baked into the building itself.   

Our panel of building performance experts will cut through the myths, answer questions, and share actionable solutions. 

We’ll be covering:   

- Do furnaces “dry out” houses? 
- Can leaky ducts waste more energy than oversized systems?
- What makes air sealing so important to a building’s efficiency? 
- Can MAD air destroy comfort? 
- When does a blower door test make sense?  
- What should you do with homes that are fundamentally flawed?   

Join ACCA’s David Bixby, manager of codes and standards, Wes Davis, director of technical services, Ed Janowiak, manager of HVACR design education, and the confirmed panel of experts shown below. Bring your questions, toughest building problems, and favorite mug — this Codes & Coffee is about to get real.
