Blower Door Testing

Air Quality Quiz

Have you experienced any of the following?

  • Frequent illness

  • Musty odor

  • High humidity

  • Moisture buildup

  • High utility bills

  • Hot and/or cold spots in your home

If you answered yes, you need a blower door test! All of those problems can be caused by air infiltration issues.

Do you know if  your house is excessive leaky or overly sealed? Without a blower door test, it can be impossible to determine where your home falls in the range of acceptable air infiltration.

Always sick? It may be your air.

  • Your home may be too tight. Or the wrong kind of air is seeping in.
  • Excessive moisture creates a damp environment for bacteria to thrive.
  • Damp under circulated air can harbor bacteria and toxins.

We want to improve your air quality and your health. By performing a blower door test, we can confirm if your house is overly sealed and recommend the best ventilation system.

High utility bills? Does your AC never shut off?

You may have:

  • Many small leaks that add up to a large problem
  • A sizable but hidden opening in your attic
  • Old or missing weatherstripping
  • Windows or door with gaps or trouble sealing

If you recently moved into your home, a blower door can reveal issues not found in the initial home inspection. Even small leaks can be a problem. Many small infiltration points can be the equivalent of one very big hole.

Do you know where your air has been?

Customers who receive a blower door test find leaks from:

  • Dusty and damp crawlspaces
  • Hot, humid attics
  • Toxin laden garages

We can help! Our skilled technicians can perform a air infiltration analysis with a blower door test to determine if your home is too tight or too leaky.

What are the benefits of a Blower Door Test?

  • A blower door test measures the amount of air infiltrating into the house.
  • A blower door test can reveal leaks hiding in places you rarely go, like attics and crawlspaces.

What is a Blower Door device?

  • A large fan is set up in your front door, the doorway is then sealed.
  • The fan blows air to the outside until the house is pressurized to 50 pascals.
  • A measurement is then taken to determine how leaky your house is. This measurement is your ACH50.


New code requirements:

  • Effective July 2017, every new home constructed in the state of Florida must pass a Blower Door inspection.

If your home was constructed prior to 2017, it likely did not have to undergo this extra level of inspection.
