What Is a Blower Door Test?
- Energy efficiency – Homes with poor insulation waste energy, leading to costly utility bills.
- Indoor air quality – Homes with air leaks may experience an influx of allergens and outdoor pollutants.
- HVAC performance – Air leakage forces HVAC systems to work harder.
- Comfort levels – Leaky homes suffer from drafts and unstable indoor temperatures.
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. By using a pressure gauge, we can measure how much air flows in through unsealed cracks, leaks, and gaps. A home with too much air leakage may benefit from additional insulation and better air sealing.
