Blower Door

A blower door test measures air leakage out of and into your home. A leaky house is draftier, uncomfortable and uses more energy. Leaky homes impact indoor air quality and the ability to keep your home at a comfortable temperature. By depressurizing your house using a blower door, we can measure air leakage in the house’s shell and identify leakage spots. (Check out YouTube below)


Duct Blaster

A duct blaster is similar to a blower door in that it measures leakage in your duct system. Ducts leak---and leaky ducts can waste up to 30% (or more) of your heating and cooling costs and cause pressure changes in your home contributing to unconditioned air infiltration/exfiltration. (See Below)


Infrared Camera

Tells the “truth” behind the walls.

When used with a blower door, an infrared camera can identify where insulation is missing or installed improperly. Thermography can measure temperature differences on surfaces and locate problem areas from air infiltration and moisture penetration (e.g., walls and ceilings).
