In years past, service technicians relied on hearing hissing sounds or detecting chemical smells to find leaks. These methods aren’t reliable, though. In fact, a small leak can make no noise or produce a minimal scent, and the exact location of a refrigerant leak is difficult to pinpoint without the right tool.

That’s where a refrigerant leak detector comes in. This device analyzes the air for refrigerant gasses, identifying the presence of any in the system and pinpointing the source of the leak. Regular use of a refrigerant leak detector also prevents minor issues from escalating into major repairs, saving time and money.

A good refrigerant leak detector is durable and easy to use. Look for one that is well-built and has a clear display, making it easy to read in poorly lit conditions. The sensitivity of the refrigerant leak detector is an important factor as well. A highly sensitive device like the Fieldpiece DR58 or Elitech ILD-200 can identify tiny leaks, preventing them from escalating into costly problems.

How to Choose the Right Refrigerant Leak Detector for Your HVAC System

Finally, a refrigerant leak detector should have a long lifespan, ideally up to ten years or more with proper maintenance. Watch for signs that it is deteriorating or needing to be replaced, such as inaccuracies and difficulty using the device. When you do need to replace your leak detector, choose a new model that offers the same functionality and features to ensure continued efficiency.
