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 frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in New Berlinville, 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?

While performing blower door test in New Berlinville, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In New Berlinville, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Achieving this goal during your blower door test in New Berlinville, PA promotes energy savings and demonstrates adherence to local building rules.

  • Seal all penetrations in exterior walls using caulk or spray foam.
  • Ensure doors and windows are properly installed, caulked, and weather-sealed.
  • Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.

Preparing for a Blower Door Test in New Berlinville, PA

To get ready for blower door test in New Berlinville, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected 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 leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in New Berlinville, PA.
