HVAC Smoke Testing with Superior® Smoke
Smoke testing effectively and inexpensively reveals leaks and other faults in heating and air conditioning duct work. The Superior method of generating smoke by chemical reaction eliminates costly equipment and time consuming operations in pinpointing HVAC leaks.
Detecting HVAC Leaks
Smoke testing has eliminated the need for tedious and time consuming soaping techniques. When smoke testing HVAC systems, smoke is traditionally introduced through the system intake. The highly visible Superior® Smoke readily blends with air allowing for the technician to quickly identify leaks in the system. Usually there are openings large enough to admit a pail or similar non-flammable container with a smoke candle in the system. We suggest introducing smoke twice the volume of the area being tested.
