The 246 Low GWP Refrigerants is an intermediate course, totaling 3 instructional hours. Students will take the module in a systematic progression that moves through foundational knowledge, into advanced, specific technologies, focusing on modern refrigerants and the systems that utilize them. Students are enrolled as online asynchronous. This access allows students to login at their convenience 24/7/365. This program is NATE recognized for 3 hours of continuing education hours (CEHs) which are applicable to NATE re-certification.

“As the HVACR industry continues to move forward and innovate, the refrigerants that were once so commonplace are now being phased out. Replacing them are more energy efficient, environmentally friendlier refrigerants, known as Low GWP refrigerants. Many of these new refrigerants are classified by ASHRAE as A2L, or slightly flammable. The industry is also seeing expanded use of some hydrocarbon (A3) refrigerants, such as propane and isobutane. Students and technicians will require additional training for the safe handling and transportation of these refrigerants.” – ESCO
