How It really works:
Seal the program by covering all vents.
Connect a calibrated fan to pressurize the duct process.
Measure the level of air dropped at a selected strain (25 Pascals).

Create a report for your personal information or allowing.
These assessments are required by Florida Strength code and make sure that your ducts meet up with legal effectiveness thresholds.
