Blower Door Testing
Blower door testing is required for a HERS rating, as well as for homes being completed under the 2009, 2012 and 2015 IECC codes. Equipment is used to depressurize the home to measure the leakage under specific pressure conditions. Our helpful staff can identify problem areas and even help prepare you ahead of time by consulting on air sealing strategies.
Duct Leakage Testing
Duct leakage testing is required for a HERS rating, as well as for homes being completed under the 2009, 2012 and 2015 IECC codes unless all ducts are kept within conditioned space. Equipment is used to pressurize the ductwork to measure air leakage. We also frequently send our experts out to your site during construction to pressurize the ducts to identify any areas of leakage before you cover up the ductwork.
Insulation and Thermal Bypass Inspections
Used as an essential tool for ENERGY STAR® certification, the inspection of insulation and thermal bypass are becoming a regular request of high performance builders. Allow our trained staff to identify areas of weakness for you and give you an extra set of eyes verifying your insulator's work. Having our extra set of eyes on it is quicker and cheaper than the rework involved with a bad insulation job.
Third-Party Airflow Testing
Our experts can test supply air flows, ventilation and exhaust air flows, pressure differentials and draft pressures. Services are performed on both new construction, as well as existing, and can help prevent or identify the source of problems within your building.
