What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. 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 Mendenhall, PA detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Mendenhall, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in PA.

What Is A Passing Blower Door Test Score?

Residential buildings in Mendenhall, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Satisfying this requirement in your blower door test in Mendenhall, PA helps optimize energy use and ensures you meet local building standards.

It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through PA’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
Apply insulation of the correct R-value and make sure it fits snugly in all areas of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>

Preparing for a Blower Door Test in Mendenhall, PA

To get ready for blower door test in Mendenhall, 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. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Mendenhall, PA energy standards.
