How clean is the air you breathe at home? The answer may surprise you. At Donovan, we perform blower door testing to help you determine the quality of the air in your home and whether it falls in the range of acceptable air infiltration.

Always sick? It may be the air you’re breathing at home

If any of the people living in your home always seem to be sick, it could be the result of the wrong kind of air seeping into your house. For example, excessive moisture creates a damp environment for bacteria to thrive, and that damp, under-circulated air can harbor bacteria and toxins that have been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, lungs, and throat.

A Blower Door Test Tells Where Your Air Has Been

At Donovan, we are committed to improving your air quality and your health. With a blower door test, our Donovan team can confirm if your house is overly sealed or if unclean air is seeping in from dusty and damp crawl spaces, hot, humid attics, or toxin-laden garages. 

Since July 2017, every new home constructed in Florida must pass a blower door inspection. If your home was constructed prior to 2017, it probably skipped this extra level of inspection, and it would be a good idea to have the test performed on your own. 

What is a blower door device?

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

Here’s how the blower door device works: 

  • A large fan is set up in your front door and the doorway is then sealed.

  • The fan blows air outside until the house is pressurized to 50 pascals.

  • A measurement is then taken to determine how leaky your house is. This measurement is referred to as your ACH50.



What are the benefits of a blower door test?

  • A blower door test measures the amount of air infiltrating your house.

  • The test can reveal leaks in places you rarely go, like the attic and crawl spaces.
