What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Hatboro, PA helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Hatboro, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Hatboro, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. By meeting this standard in your blower door test in Hatboro, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Hatboro, PA

We start the process of blower door test in Hatboro, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Hatboro, PA.
