Advanced Zonal Diagnostics
Most weatherization crews can find air leakage. This course teaches you what to do with it.
You'll move beyond blower door basics to make informed, field-based decisions about which leakage pathways should be sealed, which can be sealed, and which ones you should leave alone.

WHY TAKE ADVANCED ZONAL DIAGNOSTICS TRAINING
Benefits of Advanced Zonal Diagnostics Certification
This course gives experienced weatherization professionals the diagnostic framework to work smarter in the field — spending time on air sealing that actually moves the needle, and knowing when to stop.
Stop Guessing, Start Deciding
Learn to interpret zonal pressure readings with precision — using the Rule of 50 and Half-Pressure Rule to distinguish fully connected, partially connected, and isolated zones, and act on what you find.
Prioritize Work That Actually Performs
Apply a structured decision-making framework to separate high-impact opportunities from wasted effort. Know when to seal immediately, when to investigate further, and when to leave a zone alone.
Document and Defend Your Decisions
Leave with the skills to record diagnostic findings clearly, write defensible notes for auditors and QCIs, and support scope of work decisions with real data — not just field intuition.
"I've been doing blower door work for six years and thought I had a handle on zonal diagnostics. This course changed how I read pressure data entirely. I came back to the field thinking differently about every zone I walk into."
- Marcus Thompson

"The case scenarios were worth the whole day on their own. We worked through situations I've actually been in the field and didn't know how to call. Now I have a framework I can explain to my crew and to our QCI."
