Why have a blower door test done?

To Save Money!

The main reason would be to save money! 

How energy efficient is your home?

Does it seem like your heating and cooling costs are too high? Many of us find that it is very expensive to keep our house a comfortable temperature. 

Air infiltration can account for 40% or more of a home’s cooling or  heating cost according to the US Department of Energy. Air can escape  your home through the top plate, duct registers, lighting fixtures,  exhaust vent fans, attic hatches, soffit openings, empty wall spaces and  insulation gaps. 

A blower door test can determine the "tightness" of a home. Is your home insulated correctly? A blower door test can answer that question for you!


Simply Put

A blower door test measures the air tightness of buildings. It can also test the air tightness of the ductwork in your home. 

While performing this test, a compentent technician can find air leakage spots and recommend the correct course of action to eliminate as many of these air leasks as possible.

How does it work?

 To conduct a blower door test, a blower door fan is  placed in an entry doorway to suck out air from the interior of the house. This will depressurize the house.

What will that do?

  This process will cause outside air to be drawn into the house through leakage points. Now, using specialized equipment such as a manometer, the one of our trained professional technicians can calculate the buildings air leakage rate.

Florida Requirement

Homes in Florida must have 7 air changes per hour (7 ACH50) or less in order to pass the Blower Door test. 

Mechanical ventilation is required if a home has less than 3 ACH50 or 3 air changes per hour for the Blower Door test.
