Air infiltration is a major factor in your home's heating and cooling costs. In the winter, cold air seeps into your house, replacing warm air that escapes through leaks in your home. In the summer, the opposite occurs. Air leakage is the result of pressure differences between the inside and the outside of your house, and can be caused by temperature differences, wind, living habits and exhaust appliance use such as bathroom fans, range hoods and dryer vents.

Air sealing specialist in the past few years have developed more sophisticated ways to determine how much leakage is in a house, where that leakage is and how tightening a house will affect house pressures.

The blower door is a tool that measures air leakage in your house. It consists of a fan that fits into a doorframe. The instruments on the blower door measure how much air the fan must blow to make the house reach a certain air pressure. Air will then rush through all leaks in the house, which a technician can help you locate and seal. The blower door can also be used to measure leakage in the heating and cooling ducts.
