Duct Leakage Testing Procedure

According to IECC (International Energy Conservation Code) when a new HVAC system has been installed in a home or business you will need a duct leakage test done. Keep in mind this is obligatory to pass inspection on any home or commercial building. Only after a duck leakage test is performed and passed will the owner receive a Certificate of Occupancy.

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set

How do you know that your home has poorly performing ducts?

• You have high summer and winter utility bills
• You have rooms that are difficult to heat and cool
• You have stuffy rooms that never seem to feel comfortable
• Your ducts are located in an attic, crawlspace, or the garage
• You find tangled or kinked flexible ducts in your system

One might need duct leak testing done in NJ to receive a certificate of occupancy according to new standards for 2020. If you don’t know about this requirement when purchasing a home, try and buy a home with a functioning central air system.

NJ Air Quality has the certification to perform the test for IECC compliance.
