Blower Door Testing

Blower Door testing quantifies airflow through leaks in your home, detects energy loss, and pinpoints air intrusion

Our analysts use this important diagnostic tool to grade the performance of an existing home about to undergo energy efficiency improvements as well as ensure a tight energy efficient envelope in new construction. We advise new home builders to conduct a blower door test after the home is insulated, but before the drywall is hung. Newly enforced building codes have stringent requirements on air infiltration. This test will be able to quantify the results of your home before it is too late—or too costly—to repair the problems.

In a procedure called Blower Door Directed Air Sealing, Diversified Energy helps to locate and fix leaks in an existing house. Even homes that have been built fairly recently have major issues regarding their inability to be cooled or heated appropriately. The owners report hot or cold spots, in addition to excessive energy bills. Our first step in diagnosing the issues with these homes is the blower door test. For a more detailed and thorough audit, a homeowner may also incorporate duct blaster testing along with an infrared inspection. Of course, the DE 360 Energy Audit offers the most detailed reporting of your home’s energy deficiencies.

What Is A Blower Door?

A basic blower door consists 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. Diversified Energy only uses the most accurate blower doors that use digital measurements of air leakage for the highest levels of accuracy.

There are two types of blower doors: calibrated and un-calibrated. It is imperative that energy efficiency auditors use a calibrated door. Calibrated blower doors have several gauges or a digital interface that measure the amount of air pulled out of the house by the fan. Uncalibrated blower doors can only locate leaks in homes. They provide no method for determining the overall tightness of a building. If an auditor shows up at your home with an un-calibrated blower door, send them away and call Diversified Energy for a proper blower door test.

What Is A Blower Door Test?

A blower door test is a proven diagnostic test to check how air-tight a structure is. It is designed to measure the amount of air infiltration from air leaks in walls, attics, and mechanical penetrations. A blower door test does not evaluate how well a structure is insulated, but it does quantify the amount of air leakage, and allows our technicians to identify where the air leakage is coming from. Poorly sealed houses have higher utility bills, reduced overall comfort levels, potential mold issues caused by moisture, and reduced indoor air quality.

Your Diversified Energy Blower Door Test Includes:

  • Initial visual inspection of your home
  • Preparation of your home for the actual testing
  • Setup of blower door
  • Conducting multiple testing cycles for the most accurate measurements
  • Running the blower door during additional inspection to identify areas of air infiltration
  • Breakdown of equipment and disposal of any blower door related test materials [vent tape]
  • Provision of testing results and list of air infiltration points

You are welcome to observe and ask questions of our BPI certified technicians as they perform your Blower door test. We will provide you with final testing results regarding your home’s blower door testing performance, and recommendations of what you need fixed/repaired. If the repairs necessary are part of Diversified Energy’s scope of services, we can provide an estimate for the project as well.

How Much Blower Door Test Cost?

The cost of a Diversified Energy blower door test is based on two main criteria.

  • The conditioned [cooled/heated] square footage of your home
  • The number of installed HVAC units

The insights you will gain into the performance of your home, and the steps you can take to improve the energy efficiency and indoor air quality of your home are priceless. Our blower door test have been used as the guide for our clients to make improvements that save them hundreds or thousands of dollars per year on their cooling and heating bills, and improved the indoor air quality of their home.

    Chad from Diversified Energy spent a few hours retrofitting our home and we are already using less energy than before. Customer service was great and they explained the whole process. Highly recommend to others.

    SAVE MONEY HERE! After receiving another frustrating Cleco bill, I was connected with Diversified Energy and was able to schedule them right away. Chad was extremely informative in ways to save energy. After running some airflow test he determined I was heating not only my house but the entire neighborhood!!! He properly sealed my attic door, the space around my AC vents, changed some LED lights and also Encouraged me to finish a remodeling project in my bathroom that was causing it to lose air and heat to the home. Through these air leaks I was basically heating another 1100 sqft every month. Yes that is really bad! I’m confident that my bill will go down and I appreciate the professionalism. I highly recommend this company and ask for Chad.
