Since A2L refrigerants are designated as mildly flammable, safety features like refrigerant detection systems (RDSs) are being incorporated into new residential/light commercial ducted split systems that contain more than 4 pounds of A2L refrigerant. Here’s what HVAC technicians need to know about installing those RDS in the field.

RDSs are generally required in A2L systems that contain more than 4 pounds of refrigerant and can either be field or factory-installed, depending on the manufacturer.

Soap bubbles have long been thought of as the standard method for leak detection, but times, and technology, are changing.

While servicing equipment, technicians should be on the lookout for sources of potential future leaks, as well as follow good service practices to prevent creating leaks.

Know what type of detector you are using, know how to use it, and ensure it’s capable of detecting leaks by calibrating it on a regular basis.

According to the Centers for Disease Control (CDC), accidental CO poisoning is the cause of approximately 50,000 emergency room visits and more than 400 deaths each year in the U.S.

Before you can fix a leak, you need to find it. That’s where leak detectors come in.

Refrigerant leaks in HVACR equipment – particularly commercial refrigeration systems -- are a significant problem.

Technological developments are consistently improving the tools technicians have to use.
