What is a Blower Door Test?
The blower door test is an air leakage test for your home. It measures how leaky or tight the home is. A calibrated instrument with a fan on it is attached to the front door of the home. Air is sucked out of the house until a pressure is reached that is equivalent to having a 25 mile per hour wind blowing on all 4 walls and the roof at one time. An airflow number is captured at the test pressure. Q: How is ductwork tested? A: This test is very similar to blower door test. We measure the leakage to the outside of the home. This ensures energy is not lost to the outside air. This is important as 10% of fuel used in a typical home can be lost through the ductwork. Q: How is fresh air provided? A: We use heat recovery ventilators or pressure compensating exhaust fans by Panasonic. Q: What about mold and mildew? A: Our Warm WallT system includes exterior insulation that eliminates any possibility of condensation in the wall cavity, so mold and mildew can not occur. Q: What is EPACT? A: EPAC
