Our virtual Under Pressure: House Pressure & Chimney Systems class provides hands-on training designed to help chimney professionals better understand pressure diagnostics, draft measurements, and whole-house performance as it relates to chimney and venting systems.
This interactive virtual course focuses on practical application of diagnostic testing using a manometer. Participants will learn how to gather and interpret pressure readings, identify common house pressure problems, and better understand the relationship between the home, appliance, and chimney system.

Understanding house pressure is essential for diagnosing draft and venting problems. In Under Pressure: House Pressure & Chimney Systems, you'll learn how the house functions as a system, what causes pressure imbalances, and how those conditions affect chimney performance and safety. Through practical instruction in this one-day class, you'll gain confidence using a digital manometer, performing pressure testing, interpreting results, and identifying effective solutions to common house pressure issues you can apply in the field.
The National Chimney Sweep Guild offers virtual Under Pressure: House Pressure & Chimney Systems classes throughout the spring and summer. Class will begin at 8:00 am CT and end at 4:00 pm CT with a 45-minute lunch break and a few 10-minute breaks throughout the day. A class handout and other course materials will be emailed prior to the class. A basic manometer will be needed for certain parts of the day.

This is an interactive virtual training course. Participants should expect to actively engage throughout the session and complete diagnostic exercises using their own manometer. The class is designed to provide practical, real-world applications rather than lecture-only instruction.
Attendees are encouraged to ask questions, share field experiences, and participate in discussion throughout the program.
