Blower Door Test

A blower door is a diagnostic tool designed to measure the airtightness of a building, locating air leakage sites. A blower door consists of a calibrated fan for measuring an airflow rate, and a pressure-sensing device to measure the air pressure created by the fan flow. The combination of pressure and fan-flow measurements is used to determine the building airtightness which is useful when trying to increase energy conservation, decrease indoor air pollution, or control building pressures.

Duct Leakage Test

Duct air tightness measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, pinpoint specific areas in the duct system that require the most attention, and certify compliance with duct leakage standards (such as Energy Star® for Homes).

Infrared Testing

An infrared thermograph is used to detect small differences in surface temperatures so that problems such as missing insulation, water damage, electrical problems, and air infiltrations may be identified.

Combustion Zone Testing

Some areas in the home with combustion appliances, also known as the Combustion Appliance Zone (CAZ), may behave very differently after installing insulation or air sealing a home.  This test helps to verify that the CAZ is not being depressurized, which may cause Carbon Monoxide  spillage, flame roll out, or other dangerous events from happening.  Combustion Zone Testing is recommended when a combustion closet is located within the thermal boundary of the home.
