McGill AirFlow. Here are some of the ways to find air duct leaks. 1. Duct Leak Testing Professional HVAC contractors can easily test whether your air ducts are leaking, and how much they are leaking. HVAC ducts are supposed to be a closed system. So, if you close off registers, run the HVAC system, and test air pressure, you can see whether there are any leaks. You can carry out the building leakage tests using a gauge, fan and door panel and capture the readings on paper to later enter into FanTestic so the software can calculate compliance for you and generate a report in MS Word or put your test readings into MS Excel. This is called a Manual Test in this
