What Does a Blower Door Test Entail?
A blower door test is a rather ingenious way in which to pinpoint the source of air and moisture leaks in the home. A calibrated fan is installed in the doorway of your home, while other doors, windows, and access points are sealed off. The fan then pulls air out of your home, and the negative pressure therein will cause air from outside to be pulled in. Because the doors and windows are closed, the only way for this air to enter the home is through weak points in your home envelope. This allows us to assess just how airtight your home actually is, as well as to pinpoint problem areas which could be improved upon, helping you to live with greater indoor air quality and to cool your home with greater efficiency.
Benefits of Blower Door Testing
Some gaps in your home envelope are fairly obvious. They may allow light in, or you may feel a draft when walking by a particular window. Others may be in far less accessible areas, though. By using the information gathered during the blower door test, we’ll be able to seal up your home in a more effective manner, while ensuring that your home has the ventilation necessary for great air quality and comfort.
