What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Glen Riddle Lima, PA finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Glen Riddle Lima, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Glen Riddle Lima, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Reaching this target in your blower door test in Glen Riddle Lima, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Glen Riddle Lima, PA

To get ready for blower door test in Glen Riddle Lima, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Glen Riddle Lima, PA energy efficiency codes.
