You spend a lot of time in your home and we think you should always be comfortable in it, no matter the time of year! The blower door is a machine we use in our energy check-ups and other building performance testing. The blower door helps to pinpoint air leakage in your building’s envelope (your walls, floors, attic, ) and your duct system.
The blower door is comprised of a calibrated fan that detects air movement, a mounting system to attach the fan to, and seal off, an exterior door, and a manometer that measures pressure in the building with respect to outside. While the blower door is running, we can use other tools such as Infrared Thermal Imaging and smoke puffers to pinpoint areas of wasted energy and heat flow.
Conducting the blower door test helps us quantify airflow through a building. This is similar to finding the hole in an inflatable pool raft. The blower door test helps us determine how big a hole might be in your building; ranging from… the size of a golf ball or smaller on a Passive House to the size of a football field! From there, we can measure heating and cooling wasted through that hole, and help figure out how to cost-effectively make you more comfortable.
Our experts can provide your home or building project with a comprehensive home energy and health assessment, or energy audit. In about three or four hours, we can identify ways to improve your home's performance, assess the quality of insulation, air leakage, duct leakage, the heating and cooling system, water heater, lighting, appliances, doors, and windows.
Our Energy Checkup starts at $500 for an average single-family home. Please Contact us for an exact quote for your home or building project.
