Blower Door Testing
Blower door testing is a vital component of energy code compliance and home performance evaluation. This test uses a powerful calibrated fan mounted in an exterior door frame to measure how much air leaks out of your building envelope.
Why It Matters
Air leaks not only waste energy but also cause discomfort, moisture issues, and higher utility bills. Our blower door testing process identifies these inefficiencies so that you or your contractor can take corrective action before final inspections.
The 2021 code is now in effect in Virginia as of 1/18/2025.
This is especially important for new builds and major renovations.
What to Expect
Our technician will install a temporary fan system in an exterior doorway. The fan pulls air out of the house, reducing the internal pressure while all other openings are sealed. Instruments measure airflow needed to maintain a certain pressure, revealing the amount of air leakage. A report is generated showing the Air Changes per Hour (ACH) and whether the home passes or fails.
Benefits of Blower Door Testing
Duct Testing
In addition to blower door testing, we offer duct testing to assess the performance of your HVAC system. Leaky ductwork can cause your system to work harder, wasting energy and increasing costs.
What Is Duct Testing?
This procedure checks the airtightness of your home’s ductwork system using specialized equipment. A duct blaster is connected to the air handler or a return vent to pressurize the duct system. Pressure readings are used to determine how much air is leaking.
Duct testing is often required by local building codes and energy programs, especially in newly constructed homes.
