Blower Door Testing Services

A blower door measures the air tightness of your property. It’s made up of a calibrated fan, a mounting system to install the fan to an exterior door, and a manometer — this is what measures pressure.

Why Blower Door Tests are Necessary

  • To avoid moisture condensation issues
  • To avoid unpleasant drafts caused by the cold outdoor air leaking inside
  • To avoid air leaks that cause excessive energy consumption
  • To know how much mechanical ventilation is needed to have superior indoor air quality

How a Blower Door Test Works

  • The blower door pulls air out of the home, lowering the air pressure inside. Then, the air from the outside flows in through all the unsealed cracks and openings, as this has higher air pressure. Auditors may use a smoke pencil to find any air leaks.
  • This entire test determines the air infiltration rate of a building.
  • There are two types of blower doors: calibrated and uncalibrated. Auditors must use a calibrated door to properly measure the amount of air that the fan pulls out of the home. An uncalibrated door only helps locate air leaks in your home.
  • Uncalibrated blower doors don’t provide any way to determine the overall air tightness of your home or building, so inquire about getting a calibrated blower door. The calibrated door’s data will make it easier for an auditor to quantify the amount of air leakage. This way, we can determine the effectiveness of an air sealing job.

Preparing For a Blower Door Test

  • Expect the auditor to request access to all areas of your home. This includes built-in cabinets, attics, crawl spaces, closets, and unused rooms.
  • The auditor will need to close every exterior door and window, fireplace dampers, doors, and wood stove air inlets.
  • Only interior doors are left open.
  • Expect the auditor to set controls on fossil fuel appliances so that they don’t fire during the test. Afterward, the auditor should return them to their normal settings.
  • Plan thoroughly with your auditor. Point out areas that are drafty, or difficult to condition.
  • If you use wood as a heat source, make sure all fires are out. Not even coals are allowed to burn before the auditor arrives. Clean up ash from open fireplaces.
  • Depending on your home’s size, expect the blower door test to take awhile.
