FAQs About House Blower Door Testing
What is blower door testing?
Blower door testing is a method used to measure the air leakage rate in a building. It involves installing a powerful fan in an exterior door frame to create a controlled pressure difference, which helps identify leaks and assess the overall airtightness of the home.
Why is blower door testing important?
This testing is crucial for identifying and addressing air leaks that can lead to energy loss, higher utility bills, and reduced indoor comfort. It helps ensure that a home is energy-efficient, reduces the risk of mold and moisture problems, and improves overall indoor air quality.
How is a blower door test conducted?
During a blower door test, a fan is mounted in an exterior door frame and used to either pressurize or depressurize the home. A pressure gauge measures the airflow required to maintain a specific pressure difference, and the data helps pinpoint areas of air leakage.
What should I do to prepare for a blower door test?
To prepare, make sure all doors and windows are closed and locked, and remove any obstructions from around the testing area. It's also helpful to ensure that the home's heating or cooling systems are turned off to avoid interference with the test results.
How often should blower door testing be done?
Blower door testing is typically recommended when building a new home, during major renovations, or if you suspect air leaks in an older home. It can also be beneficial to perform testing periodically to ensure ongoing energy efficiency and address any new issues that may arise.
