Our experienced technicians provide detailed reports and recommendations based on blower door test results, guiding you through the process of improving your building's energy performance and indoor air quality.
What Is a blower door test?
Blower door testing is a diagnostic procedure used to measure a building’s airtightness and identify air leakage points. During the test, a powerful fan is mounted on an exterior door or window, and the building is depressurized to simulate windy conditions. By measuring the airflow through the fan and monitoring pressure differentials, we can pinpoint areas where air infiltration or exfiltration occurs, such as gaps, cracks, and openings in the building envelope.

Whether you’re constructing a new building, renovating an existing home, or simply looking to improve energy performance, our blower door testing services provide valuable insights and actionable solutions.
why get a blower door test?
Indoor Air Quality
Air leaks can allow pollutants, allergens, and outdoor contaminants to enter the home, affecting indoor air quality. Blower door testing helps create healthier living environments by reducing infiltration of pollutants.
Building Performance
Blower door testing is a crucial step in achieving green building certifications, such as LEED, ENERGY STAR, or Passive House, by demonstrating compliance with airtightness standards and energy efficiency requirements.
Energy Efficiency
Identifying and sealing air leaks can significantly reduce energy consumption by minimizing heat loss or gain, leading to lower utility bills and improved comfort.
Diagnostic Tool
A blower door test serves as a diagnostic tool to identify building envelope deficiencies, allowing for targeted air sealing measures and more effective insulation strategies.

Blower Door Testing is a diagnostic tool used to measure the airtightness of buildings. It helps identify air leaks and drafts by creating a pressure difference between the inside and outside of the building. This test is crucial for improving energy efficiency, indoor air quality, and overall comfort.
Blower Door Testing is important because it helps detect hidden air leaks that can significantly impact a building’s energy efficiency. By identifying and sealing these leaks, homeowners can reduce energy bills, enhance indoor comfort, and ensure better performance of heating and cooling systems. It also helps in meeting building codes and standards for energy efficiency.
Blower Door Testing is conducted using a powerful fan mounted on an exterior door frame. The fan blows air out of the building, creating a lower pressure inside compared to the outside. This pressure difference forces air to enter the building through any gaps or cracks. Technicians use smoke pencils, infrared cameras, or other tools to locate these leaks and quantify the building's airtightness.
You should consider Blower Door Testing if you are constructing a new home, renovating an existing one, or experiencing high energy bills, drafts, or inconsistent indoor temperatures. It is also recommended before installing a new HVAC system to ensure it will operate efficiently and after major sealing or insulation projects to verify their effectiveness.
To prepare for a Blower Door Test, ensure all windows, exterior doors, and vents are closed. Turn off any combustion appliances and make sure any fires are extinguished. Remove any obstructions near the door where the fan will be installed. Inform the testing technician of any known issues or specific areas of concern in your home or building.
