Training for the A2L Refrigerant Transition from ESCO Institute!
Although R-410A will remain available in limited quantities for maintaining legacy systems, HVACR professionals must now become proficient with R-32 and R-454B and the equipment that relies on these refrigerants to operate effectively and efficiently. It is therefore crucial to start learning about these technologies and refrigerants if you have not already started to do so.
To support this transition, ESCO Institute is committed to keeping you informed about the latest in refrigerant changes and the resources available to help keep you in lock step with the industry.
