Understanding how a blower door test works can help you see just how valuable it is for improving your home’s energy performance. This diagnostic test is designed to measure the airtightness of your building by identifying where and how much air is leaking through cracks, gaps, or poorly sealed areas. At Thermal Plan, we use advanced equipment to deliver precise results, helping you make smarter insulation and sealing decisions.
Here’s a quick breakdown of the process:
Setup of the Blower Door Fan
A powerful fan is mounted in an exterior doorway and sealed with a temporary frame to control airflow.
Air Pressure is Measured
The fan pulls air out of the home to lower the pressure inside, allowing outside air to flow in through any unsealed openings.
Leak Detection Begins
Using tools like smoke pencils and infrared cameras, we locate exactly where air is entering or escaping the building.
Data Collection & Analysis
We measure the air changes per hour (ACH) and provide a full report on your home’s air tightness.
Recommendations for Improvement
Based on the results, we offer clear solutions—such as air sealing, insulation upgrades, or retrofits—to boost energy efficiency and comfort.
Your home might look sealed from the outside, but hidden air leaks could be silently draining energy and driving up your utility bills. With Thermal Plan’s professional blower door testing, we take the guesswork out of insulation by identifying exactly where air is slipping in—or out. Using precision equipment, we uncover weak points in your home’s envelope so you can target improvements that truly matter. Whether you’re prepping for new insulation, building a high-efficiency home, or trying to cut energy costs, our blower door test gives you the insights to insulate smarter and live more comfortably.
