Every heating, ventilation, and air conditioning (HVAC) system should be free from leaks to be efficient and safe. However, leaks can be introduced into HVAC systems during manufacturing and assembly, and aging HVAC systems can develop leaks over time. Because many refrigerant leaks are small, they ...

Helium leak testing: from airbags to air-conditioning units and fuel rails, from anything implanted in the body to hermetically sealed enclosures for integrated circuits, there are some instances where the acceptable leak rate is so small it’s practically zero. Since air leak test methods such as ...
