Blower Door Test in Zieglerville, PA

Evaluate your home’s air leakage and achieve energy compliance with precise blower door test in Zieglerville, 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 is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Zieglerville, PA enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Zieglerville, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

In Zieglerville, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Achieving compliance in your blower door test in Zieglerville, PA helps improve energy efficiency and meet all local code mandates.

Why Do I Need A Blower Door Test?

The State of PA and local municipalities have implemented the IECC code, which mandates blower door test on new and remodeled residential homes. We often collaborate with home builders, contractors, and homeowners who require blower door test in Zieglerville, PA to meet energy efficiency standards and close permits. A duct leakage test is sometimes required if any HVAC components or duct lines are found beyond the building’s thermal envelope. Learn more about energy code compliance.

By performing blower door test in Zieglerville, PA, homeowners can identify where conditioned air escapes. Depressurization makes leaks visible, uncovering ways to enhance comfort and efficiency. Completing a blower door test takes just a few hours, yet its long-lasting impact enhances comfort and performance in every PAseason.

How To Pass A Blower Door Test:

  • Anticipate potential air leaks before testing begins.
  • Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
  • Place insulation with the accurate R-value and check for proper installation and full coverage in 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 all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
  • Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
  • Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>
  • In most situations—over 90% of the time—we get a passing score within two hours and finalize all required paperwork.

Preparing for a Blower Door Test in Zieglerville, PA

Preparation for blower door test in Zieglerville, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust 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 all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Zieglerville, PA.
