What Is a Blower Door Test?
- Energy efficiency – Energy loss from leaky homes causes utility bills to rise.
- Indoor air quality – Unchecked air leaks can introduce outdoor pollutants and allergens indoors.
- HVAC performance – Air leakage forces HVAC systems to work harder.
- Comfort levels – Drafty conditions and fluctuating temperatures occur due to excess air leakage.
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 pressure gauge is designed to measure the airflow entering a building through leaks, gaps, and unsealed cracks. Too much air escaping from a home may indicate the need for better insulation and air sealing.

Texas Energy Code Requirements for Blower Door Testing
The 2018 IECC mandates that Texas homes meet these specific air tightness requirements.
- 3-5 (Air Changes Per Hour at 50 Pascals) depending on location.
- Homes exceeding this air leakage limit may require additional air sealing measures.
A duct leakage test must be carried out if any part of the HVAC system, like ductwork or an air handler, is installed outside the conditioned area.
