What is a Blower Door Test Procedure?

A blower door is a powerful fan that mounts into the frame of an exterior door and is used to test how airtight a building is. Some of the reasons you want to know how airtight your building includes:
  • Reduce your energy consumption due to air leakage.
  • Avoid moisture condensation problems.
  • Cut down on uncomfortable drafts caused by cold air leaking in from the outdoors.
  • Determine how much mechanical ventilation might be needed to provide acceptable indoor air quality.

How Does The Test Work?

Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow. The fan depressurizes the building, creating a vacuum. The higher outside air pressure then flows in through all unsealed cracks and openings. We use infrared imaging to determine the location of the leaks. With the data we collect, you can figure out where the air is getting in. Then you are able to properly air seal the building to provide you with better energy efficiency. After you complete air sealing, we can re-test to determine the effectiveness of the air sealing measures.   Remember it is best to let a blower door test company, such as us, handle these tests. You know that you will get accurate reports with us. Schedule an appointment with our professional contractors today.

When is a Blower Door Test Required?

Since the adoption of the 2015 IECC Residential Energy Codes, blower door air leakage testing is now a requirement for most construction projects in the Denver Metro area. This includes new construction and renovations where the addition is 30% or larger than the original home. The benefits of using our company for your testing services:
  • Test new builds or remodels.
  • Receive a compliance letter the same day.
  • Have access to multiple professionals with testing equipment.
  • Get scheduled within 2 business days.

ACH Requirements:

These are the ACH requirements that you need to be aware of:
  • Single-family homes - 3 air changes per hour or less, or 3 ACH.
  • Townhomes with attached common walls - 4 ACH in Denver County.
  • ADU’s - 4 ACH in Denver County.
  • Additions: Required for additions that are more than 30% of the original square footage or the home, not including the basement.  A Pre-test is performed to determine the air leakage of the original home. This ACH number is the benchmark for the final test post-construction. The final test must be less than or equal to the pre-test.  Performing a pre and post-test is much easier to pass since there is no specific ACH required to pass. If a pre-test is not conducted, then 5 ACH or less is required. We highly recommend that you perform a pre and post-test to increase your chances of passing this test.

I'm prepping for the tasks I know I can handle, but will almost certainly want to consult with or... Read More
