About Us
What We Do
Ellijay Blower Door offers code-required building envelope tightness testing, also known as a blower door test, to residential builders and homeowners throughout North Georgia. We also offer duct tightness (or duct blaster) testing.
What is a Blower Door Test?
A blower door test (also known as a door fan test, building envelope tightness test, or air tightness test) tells you how airtight a house is.
We use specialized equipment to depressurize your home to -50 Pa, then measure the amount of airflow that is coming into the home through plumbing and lighting fixtures, around windows and doors, and through the walls and ceilings.
The amount of airflow into the home is divided by the volume of the conditioned space within the home to arrive at an ACH50 calculation. ACH stands for air changes per hour. State and local building codes require new homes to measure below 5.0 ACH50.
What is a Duct Blast Test?
A duct blast test (also known as a duct tightness test) determines how airtight a home's HVAC duct system is. It is similar to a blower door test, but instead of depressurizing the home, we pressurize the duct system.
Duct blast tests are usually conducted at 25 Pa. The amount of air leakage is divided into the square footage of the home to determine a leakage ratio. IECC and GA building codes require post-construction total duct leakage in new homes to test below 6%.
