A blower door test will identify ALL air leaks and give you peace of mind that your home is operating efficiently.

What is Blower Door Testing?

A blower door test is the lowering of air pressure inside the house by pulling air out determining the infiltration rate of a building.

A powerful fan of variable speeds is placed in the frame of an exterior door surrounded by flexible panels to fit.

Both a pressure gauge to measure the difference between the pressure inside to the pressure outside and an airflow manometer with a hose to measure airflow.

Why is Blower Door Testing important?

A blower door test will determine the current air leakage in the home. When used in conjunction with an IR camera or smoke pencil can help identify small cracks and openings in the home’s shell that need to be sealed, lowering the cost of an energy bill.

When should I get Blower Door Testing?

Consider scheduling a test if you are thinking of buying a home, building a new home or noticing a draft in your home.

What should I Expect During a Blower Door Test?

Our experts need total access to your home. This includes closets, built-in cabinets, attics, crawl spaces and other unused rooms.

Our experts will be setting controls on all atmospheric fossil fuel appliances; this ensures they do not fire during the test and will be returned to their original position after.

The test will take up to an hour or more.
