How to fill out duct leakage test

How to fill out duct leakage test:

1. Prepare all necessary tools and equipment for the test, including a duct leakage tester, tubing, and a pressure gauge.
2. Start by sealing off all the outlets and returns in the HVAC system.
3. Connect the duct leakage tester to the supply side of the duct system.
4. Set the pressure gauge to the desired test pressure, typically 25 Pascal.
5. Gradually increase the pressure until the desired test pressure is reached. Allow the system to stabilize at this pressure for a few minutes.
6. Record the pressure reading on the pressure gauge and note down any visible leakage from the duct system.
7. Repeat the process for the return side of the duct system, connecting the duct leakage tester to the return side and following the same steps.
8. Once both the supply and return sides have been tested, calculate the total duct leakage by adding the leakage values from both sides.
9. Fill out the duct leakage test form, recording the test pressure, measured leakage, and any relevant details or observations.
10. Sign and date the form, and ensure that it is properly filed and documented for future reference.

Who is required to file duct leakage test?

Contractors, building owners, or HVAC system installers may be required to file a duct leakage test depending on local building codes or regulations.

How to fill out duct leakage test?

To fill out a duct leakage test, the tester must measure the air pressure within the ductwork and use a flow hood to determine the amount of leakage.

What is the purpose of duct leakage test?

The purpose of a duct leakage test is to ensure that the HVAC system is properly sealed and functioning efficiently, as excessive leakage can lead to energy waste and poor indoor air quality.

What information must be reported on duct leakage test?

The duct leakage test report should include the test procedure used, the measured leakage rate, the location of leaks, and any recommendations for sealing or repairing the ductwork.

When is the deadline to file duct leakage test in 2023?

The deadline to file a duct leakage test in 2023 will vary depending on local regulations or building code requirements.

What is the penalty for the late filing of duct leakage test?

The penalty for late filing of a duct leakage test may include fines, citations, or potential delays in project approvals or permits.
