A Blower Door Test helps identify air leaks in your home or building by using a special fan and door frame that is temporarily installed in an exterior door. After preparing the HVAC, plumbing, and fireplace components, the Blower Door fan is operated in order to de-pressurize the indoor space and identify the main sources of air leakage. The test typically takes about an hour to complete, including set up and tear down, and is the best diagnostic tool to use in identifying and quantifying air leaks. Amazingly, the average home in the United States has enough air leaks to be equivalent to leaving a medium-sized window open 24-hours a day, every single day! Our experts can test, diagnose, and implement a plan to reduce air leakage and improve energy efficiency and comfort.
