Blower Door Test in Lenni, PA

Improve insulation performance and meet energy code requirements through thorough blower door test in Lenni, PA. Our certified team helps homeowners, builders, and contractors locate air leaks, enhance indoor comfort, and meet all PA energy efficiency requirements.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Lenni, 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 carry out blower door test in Lenni, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

In Lenni, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Meeting this benchmark in your blower door test in Lenni, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Lenni, PA

We start the process of blower door test in Lenni, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Lenni, PA building codes.
