Blower Door Test

• Feel Drafts?
• High Energy Costs?
• Insulation not performing?
• Where are all of the dust, spiders and odors coming from?
• Do you have ice damming?

By measuring the air flow through the fan and its effect on the air pressure in the home or office, the blower door system measures the air tightness of the entire building envelope.

These problem spots are easier to find using the infrared camera to determine the air infiltration points to help with evaluating indoor air quality.
