Why a Blower Door Test?

Whether too tight, or not tight enough, your home’s air tightness has a big effect on how your home operates. Insufficient air tightness can lead to outside air invading your home, creating uncomfortable drafts, while not enough airflow can lead to excess moisture and condensation, which can cause mold and mildew. Blower door tests performed on your home can help determine what measures need to be taken in order to ensure adequate ventilation to avoid these foreseen problems.

So How Do They Work?

A blower door is a powerful diagnostic tool used to determine a home’s air tightness. By using a large fan that mounts into the frame of an exterior door, the fan pulls air into the home from outside the building envelope, putting the house under negative pressure. Acting like a 30 mph wind would on your home, the higher outside air pressure flows through all unsealed openings in the home. Our service team then investigates the home using a thermographic camera to detect locations of air leakage and intrusion.
