What Is a Blower Door Test?
- Energy efficiency – Homes with air leaks lose energy, resulting in increased utility costs.
- Indoor air quality – Leaky buildings can let in unwanted allergens and harmful pollutants.
- HVAC performance – Air leakage forces HVAC systems to work harder.
- Comfort levels – Temperature inconsistencies and drafts stem from excessive air leakage.
How Does a Blower Door Test Work?
During a blower door test, a powerful fan placed in an exterior doorway creates a pressure imbalance between the interior and exterior of the home. Air infiltration through unsealed gaps, cracks, and leaks is precisely measured with a pressure gauge. When a home has too many air leaks, improving insulation and sealing gaps may be essential.
