Heating, Ventilation, and Air Conditioning (HVAC) systems are essential for maintaining indoor comfort in both residential and commercial buildings. For manufacturers, ensuring these systems are free from leaks is critical for product reliability, safety, and performance. HVAC systems have many smaller components 
that can experience leaks over time from pressure and vibrations. These leaks can vary from automotive air conditioning leaks due to vibrations to leaks from faulty seals hoses or valves due to wear and tear.
Individual HVAC components undergo leak and flow tests during the manufacturing process on the production line to ensure the leak and flow rates are within the specified rating. The final HVAC system or assembly can be tested using a sniffer or tracer gas leak detection method.
Most HVAC manufacturers prefer our F620 for individual HVAC components leak detection testing and the He-490S for final HVAC assembly leak testing.
