What Is a Blower Door Test?
- Energy efficiency – Leaky houses consume more energy, making utility bills more expensive.
- 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 – Homes with excessive air leakage often experience drafts and inconsistent temperatures.
How Does a Blower Door Test Work?
A mounted fan on an exterior door is used in a blower door test to manipulate air pressure inside and outside a home. A specialized pressure gauge calculates the airflow entering through unsealed cracks, leaks, and gaps. Homes with excessive air leaks may require insulation enhancements and proper air sealing.
