Webinar: Blower Door Testing & Its Impact on HVAC Sizing

Are you ensuring your HVAC systems are designed for maximum efficiency and code compliance? Proper airtightness is a critical factor in determining HVAC system performance, energy consumption, and overall indoor air quality. Blower door testing is a key diagnostic tool used to measure air leakage in buildings, helping professionals design and verify energy-efficient homes and commercial buildings.

Join us for this in-depth webinar, where we will break down the importance of blower door testing, its role in HVAC system design, and how it impacts code compliance and long-term building performance.

Three Key Lessons Learned from the Field:

1.    Right-sizing HVAC is crucial – Many homes and buildings suffer from oversized HVAC systems due to outdated assumptions about air leakage. A tighter home means lower heating and cooling loads, leading to more efficient, properly sized equipment.

2.    Ventilation must be carefully designed – Airtight buildings require balanced mechanical ventilation systems (HRVs/ERVs) to maintain healthy indoor air quality and prevent moisture-related issues such as mold and condensation.

3.    Small leaks can cause big problems – Even minor leaks around attic hatches, recessed lighting, and electrical penetrations can significantly impact energy efficiency and thermal comfort. Addressing these leaks can make a major difference in both blower door test results and HVAC performance.
