Blower Door Testing & Duct Leakage Testing

Blower Door Testing & Duct Leakage Testing gives you an idea of the energy efficiency of your home.

A Blower Door Test measures the air changes per hour in a home. It’s normal for air to change and that’s a good thing to keep fresh air. Excessive air changes however, require the new air to be reheated or cooled causing significant energy loss.

A Duct Leakage Tests measures the home for leaks in the homes ductwork. It is estimated that 30% of the air which we pay to heat or cool is lost to leaks in the ductwork system. This lost air may end up in the walls, an unfinished basement, attic or crawl space. The duct blaster machine puts a number on the amount of duct leakage and helps us find and repair leaks. 


The state of Pennsylvania has adopted the 2015 IECC, International Energy Conservation code for single family buildings and the 2018 International Energy Conservation code for multi-family buildings. The change will have some significant implications for home builders and HVAC contractors operating in the state.

The codes state that each house or unit built must undergo a mandatory Blower Door Test. If you are installing an HVAC unit out of the buildings envelope such as in a basement or crawl space you will be required to perform a Duct Leakage Test as well.
