Blower Door Test = Determining Where To Properly Seal Your Home To Save Energy

During a blower door test, the fan pulls air out of the house, lowering the pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings.

It's important to understand how a home uses and loses energy. Give us a call to schedule a FREE whole home energy evaluation.
