People Also Ask about

How do you measure duct leakage?

For the rough-in test, leakage measurement is made across the system, with the manufacturer's air handler enclosure if it is installed. The test is conducted at 0.1 inches w.g. (25 Pa) with all registers taped or sealed.

What is a good duct leakage test?

The test attempts to measure the CFM25 value for leakage in the duct system to outside of the conditioned space. Standard: The measured duct leakage must not exceed 0.06 CFM25 x floor area (in square feet) served by the system.

How to check for duct leakage?

As a homeowner, you can check your exposed ductwork for leaks by doing a visual inspection. Look at the exposed air ducts for holes or gaps at ductwork connecting points. For larger leaks in exposed ductwork, you may be able to feel hot or cold air escaping. Connection points are the most common trouble spots.

How to calculate total duct leakage?

A percentage of volume flow is also a simple calculation for the testing contractor. For example, suppose you have a duct system where the duct system is handling 14,000 cfm. If the allowable leakage is specified as 2%, then the allowable leakage is 0.02 x 14,000, or 280 cfm.

What are the results of a duct leak test?

Typically, with existing homes, the results from our tests must show less than 10% duct leakage. International Energy Conservation Code (IECC) requires less than 3% – 4% duct leakage for new home construction, depending on the climate zone.

How to tell if ductwork is leaky?

As a homeowner, you can check your exposed ductwork for leaks by doing a visual inspection. Look at the exposed air ducts for holes or gaps at ductwork connecting points. For larger leaks in exposed ductwork, you may be able to feel hot or cold air escaping. Connection points are the most common trouble spots.
