Can you share a bit more about the importance of training?
Joe: Training is paramount in getting ahead of the curve. From a business perspective, owners and managers must consider regulatory compliance, refrigerant costs, and supply chain availability, all of which can impact operations and profitability. Technicians and frontline staff need the right training and confidence to handle A2L refrigerants effectively and educate homeowners. Ensuring the entire team is prepared will help create a seamless experience for everyone.
Keep in mind: To legally and safely handle A2L refrigerants, technicians need to hold an EPA 608 Certification. While current EPA standards include A2L refrigerants, the EPA test and study guides only provide a basic understanding. Technicians should take a professional A2L training course to fully understand these refrigerants and set themselves up for long-term success. Although there are no current national requirements for a specific A2L certification, obtaining one is highly recommended.

1. Manifold Gauges
   • Analog Gauges: Ensure the gauges have the correct refrigerant listed on the dial for quick reference to saturation temperatures.
   • Digital Gauges: Check the menu on your digital manifold for R-32 or R-454b. If these refrigerants are not listed, you will need to purchase a set compatible with A2L refrigerants.
2. Tool Equipment
   • Ensure that recovery machines, vacuum pumps, recovery tanks, leak detectors, wireless probes, and other equipment are certified by the manufacturer for use with A2L refrigerants.
3. Hoses and Adapters
   • Current hoses have right-hand threads, while new refrigerant tanks for A2L refrigerants have left-hand threads. Technicians will need to purchase adapters or new charging hoses with left-hand threads on the bottle side.

Check with the manufacturer directly if there is uncertainty about tool compatibility or visit manufacturer websites such as www.trutechtools.com.
