What Is a Blower Door Test?
- Energy efficiency – Poorly sealed homes waste energy, driving up monthly utility expenses.
- Indoor air quality – Uncontrolled drafts can bring in airborne irritants, including allergens and pollutants.
- HVAC performance – Air leakage forces HVAC systems to work harder.
- Comfort levels – Uncontrolled air leaks create drafts and temperature variations indoors.
How Does a Blower Door Test Work?
A blower door test utilizes a mounted fan on an exterior door to create a pressure variation between the inside and outside of a house. A specialized pressure gauge calculates the airflow entering through unsealed cracks, leaks, and gaps. Excessive air loss in a home could mean that air sealing and insulation improvements are necessary.
