Verify your home’s airtightness and meet energy-efficiency standards with a professional blower door test in Kulpsville, 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 checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Kulpsville, PA assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Kulpsville, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

Homes in Kulpsville, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Achieving this goal during your blower door test in Kulpsville, PA promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Kulpsville, PA

When preparing for blower door test in Kulpsville, PA, we first switch off the home’s heating, cooling, and exhaust systems. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Kulpsville, PA.
