A clear 2025 guide to blower door and duct leakage testing for Nashville and Middle Tennessee. What the tests are, why they matter, how to prepare, how to pass, typical costs, and what happens next.

Can a Blower Door Test Improve Indoor Air Quality?

Sealing uncontrolled air leaks helps keep pollutants, allergens and moisture from entering your living space. Once leaks are sealed, you can focus on controlled ventilation, which improves indoor air quality.

What equipment do you use in a blower door test?

I bring a calibrated blower door fan, an adjustable door frame with a nylon panel and digital pressure gauges. The equipment measures airflow and pressure differences to calculate how leaky your home is.

Do you work directly with home builders and inspectors?

Yes. Many of my clients are builders or contractors who need testing for code compliance. I coordinate with project managers, schedule tests at key milestones and deliver reports that inspectors and code officials accept.

How do I interpret a blower door test score?

Blower door test scores are expressed in air changes per hour at 50 Pascals (ACH50). A lower number means your home is tighter and more energy efficient. For example, 3 ACH50 is typical for new homes; higher scores indicate more leakage and opportunities to seal gaps and improve comfort and efficiency.
