Precision diagnostics for homes and new construction.
Blower Door Testing
A blower door test measures how airtight your home is. We mount a calibrated fan in your doorway, depressurize the house, and measure exactly how much air is leaking in or out. The result — your ACH50 score — tells you and your contractor exactly how leaky your building envelope is.
Duct Leakage Testing
Leaky ducts are one of the biggest hidden energy wasters in any home. Our duct blaster test pressurizes your duct system and measures how much conditioned air escapes before it reaches your living spaces. Required for new construction under IECC 2021 in most Midwest states.
