Hi everyone, I’m considering a blower door test for my home, but I have a few questions. How accurate is the test in detecting air leaks, and are there any common issues people face during the test? Any advice would be great!

Hi there! The blower door testing is quite accurate in detecting air leaks; it measures the rate of air infiltration by depressurizing your home and identifying areas where air escapes. Common issues people face include improperly sealed windows or doors, which can affect the test's accuracy. Also, make sure to close all vents and dampers before the test to avoid skewed results. The test can pinpoint even minor leaks, allowing you to improve your home’s insulation and energy efficiency. Overall, it’s a highly recommended step if you want to reduce energy bills and create a more comfortable living environment.

For example, older homes might show more leaks due to wear and tear. However, this can be a good thing as it provides a clear roadmap for improvements. If the results show significant air leaks, you might need to take additional steps, like upgrading insulation or sealing gaps. It's a worthwhile investment in the long run for improving comfort and reducing energy bills.
