Blower Door Testing Explained
What is blower door testing?
A blower door test is a way to measure the airtightness of a building. The test involves closing all doors and windows in the building, and then sealing a large frame with a fan in it to the doorway. The fan is turned on, and the pressure inside the building is reduced. This causes outside air to flow into the building through any cracks or openings. The amount of air that flows into the building is measured, and this can be used to calculate the overall airtightness of the building. Blower door testing is an important tool for energy efficiency, as it can help identify areas where air is escaping from the building. In addition, blower door testing can also be used to assess the effectiveness of insulation and identify drafty areas in a home. As a result, blower door testing is a valuable tool for anyone looking to improve the energy efficiency of their home.
The cost of blower door testing can vary depending on the size and age of your home, as well as the number of doors and windows that need to be tested. Issues that are typically discovered during blower door testing include air leaks, drafts, and poor insulation. In most cases, the cost of blower door testing is worth the peace of mind that comes with knowing your home is well-sealed and energy-efficient. However, if you are concerned about the cost of blower door testing, there are a few ways to save money. Many utility companies offer discounts on blower door tests, and some states even require that homes be tested for energy efficiency before they can be sold. As a result, it is always worth checking for discounts and incentives before scheduling a blower door test.
