Insulation Explanation

What Happens During a Blower Door Test?

During a blower door test, a technician will install a calibrated fan on one of your doors or windows to test the indoor environment like to determine your air change rate. When the fan is switched on, it creates a pressure difference between the inside and outside of your home. Usually, the fan sucks air out of the home, creating negative pressure inside the home. That means that the air outside is going to come in, and it will come in through unsealed cracks, windows, and other openings giving us an idea of how many air changes per hour. The higher the number of air changes per hour, the more problems you’re having with air leaking from your home.

How Is Air Leakage Measured?

A technician inside your home can usually pinpoint the exact areas of air leakage. But the best way to measure the air leakage is through the blower itself. A calibrated blower can be adjusted, allowing a skilled professional to measure the exact amount of air leaking into your home.

If that’s confusing, try to think of it as a bucket of water.

You can measure a leaky bucket by pouring water into it. If you pour water faster than the bucket leaks, the bucket will continue to fill. But if you fill the bucket at the same rate as the leakage, the water level won’t rise. If you know the rate at which you’re pouring water into the bucket, you’ve determined the rate that it’s leaking. 

A blower door test does the same thing. The technician can adjust the speed of the blower fan until it achieves equilibrium with the leakage of your house. These measurements are given in units called CFM, or cubic feet of air per minute. This number can then be converted to a standard metric called ACH50, or air changes per hour at the standard pressure of 50 pascals.

In other words, your home’s ACH50 score can be used to compare the air leakage in your home versus others. A 3 ACH50 score would be desirable for newer homes, though older homes may be a bit above this.

What to Expect From a Blower Door Test

If you schedule a blower door test, there are some things you may wish to know beforehand.

Be Prepared to Give the Technician Full Access to Your Home

During the test, your technician will need full access to all areas of your home, including your attic, crawl spaces, and even your closets.

Know Your Leaks Beforehand

You will likely do a walk-through of your home prior to the test. If you are already aware of any leaks, point them out to your technician.

Remove Any Ash From Your Fireplace

Make sure all your fires are completely out, even if you heat them with coal or wood. Before the technician arrives, clean up the ash from your fireplace to avoid having it blow everywhere during the test.

How Long Will the Test Take?

Typically, a blower test will take about an hour, though it may take longer for larger homes, or older homes that may have more air leaks to identify.

What Are the Next Steps?

If your home contains air leaks, one of our professionals can recommend some solutions to ensure your home is properly sealed. This may include chemical sealants, or physical measures such as flashing or weather stripping around windows, doors, and vents. Your technician can provide recommendations that are right for you and your home.
