- The test measures air leakage and identifies drafts by creating negative pressure in the house and detecting air infiltration through gaps and cracks.
- Infrared thermal imaging cameras are used to visually display and photograph insulation levels and identify cold or hot spots in walls, ceilings, and floors.
- The test helps locate the worst air leaks, allowing for targeted sealing and insulation improvements.
- Minimum ventilation requirements are calculated to ensure proper indoor air quality.

- The first is the evaluation, which involves a walk-through of the building to highlight appliances and systems that use up energy.
- Afterward, auditors conduct an air tightness test. Also known as the blower door test, this process checks for air leakage and seals up cracks.
- Lastly, you’ll get recommendations on how to improve your energy efficiency.
Benefits Of Blower Door Test

- Thermal imaging is a non-invasive method that helps diagnose heat loss in winter and heat intrusion in summer.
- By making the invisible visible, thermal imaging reveals areas with missing insulation and the impact on heat loss or gain.
- It helps identify electrical faults, insulation deficiencies, water and moisture intrusion, energy loss, and potential structural defects.
- Infrared images assist in recommending actions for improvements and estimating the costs of services such as insulation, air sealing, and more.

- The fan comes with a very powerful variable speed feature that sucks air by creating negative pressure in the house’s interior.
- To prevent air from escaping, a dense cloth seal is usually a part of the home blower door equipment. It is mounted around the door frame while the far is inserted into it.
- Infrared Camera: This camera allows auditors to see through walls and detect leaky areas or parts of the house without insulation
- Pressure Monitor: Auditors require this device to get information about the level of air within the home as well as the speed at which air leaks.
