The blower door test is a tool that helps measure the air-tightness of your home. It allows you to discover the most common points of leakage and fix them. This will allow you to make a more energy efficient home.

The test is often conducted at the end of the construction process. The equipment used in the test includes a fan and pressure tubes. These tubes are connected to a gauge, which interprets the data into measurable results.
The pressure and flow gauge is the hub of the blower door test. This gauge pulls data from the pressure tubes and provides data on the hole to zone.
The gauge also measures the air flow and depressurization in the house. Once the parameters have been set, the energy auditor will begin the test.
Air leakage in the envelope can be tracked with a thermal imaging camera. Leaks can be identified by a white vapor trail.
The test can help you determine whether your building meets design requirements for a certain climate. In addition, it can also determine if you need additional air sealing.
The test is a requirement on all new construction for residential homes. New homes in climate zones 1 and 2 must meet tightness levels of 3. ENERGY STAR new construction guidelines require 4 ACH50 for climate zones 1 and 2.
Blower door testing is a critical diagnostic tool. It can reveal the difference between a drafty home and a comfortable one. You can also use the blower door to check your ductwork for air leaks.
