Blower Door Testing for Lehigh Valley Homes & New Construction

Straightforward, science-based testing that reveals how airtight your home really is — the foundation of comfort, efficiency, and performance.

Measure before you improve — it’s the science behind comfort.

Why It Matters

Every home leaks air — the question is how much. A blower door test measures that leakage precisely, showing where your home wastes energy and loses comfort.

A tighter home stays warm in winter, cool in summer, and balanced year-round. Whether you’re chasing comfort or meeting Pennsylvania’s 2018 IECC code (≤ 3 ACH50), testing is the first step toward measurable improvement.

How the Test Works

We mount a precision fan in your exterior doorway and pressurize or depressurize the house. Sensitive gauges measure airflow, while infrared imaging pinpoints leaks in real time.

Tests take about one hour. Everything is handled in-house by our BPI-certified technicians — no subcontractors, no shortcuts.

Who We Test For

  • Existing Homes — Ideal for homeowners who want to find and fix hidden air leaks before spending money on insulation or HVAC upgrades. Our testing identifies duct leaks, attic bypasses, and other unseen energy losses that drive up bills and discomfort.
  • New Construction & Builders — Required under the 2018 IECC code for most new homes in Pennsylvania (≤ 3 ACH50). We provide full documentation and certification so you can pass inspection the first time.
