What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Lederach, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Lederach, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Lederach, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching the target during your blower door test in Lederach, PA guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

Across PA, the IECC (International Energy Conservation Code) is adopted by the state and local jurisdictions, requiring blower door test on residential constructions and renovations. We often collaborate with home builders, contractors, and homeowners who require blower door test in Lederach, PA to meet energy efficiency standards and close permits.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
Fit insulation with the correct R-value and make sure it’s installed without voids across the entire building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Local code departments usually provide a checklist to assist with compliance — see the Philadelphia example here.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
Typically, over 90% of the time we record a passing score in two hours and handle all permit-related documentation.

Preparing for a Blower Door Test in Lederach, PA

Before conducting blower door test in Lederach, PA, we make sure all heating, cooling, and ventilation fans are switched off. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Lederach, PA.

Blower Door Test for Contractors in Lederach, PA

For contractors overseeing blower door test in Lederach, PA, most properly insulated homes can manage small on-site repairs during testing.
