A2L Refrigerant Tools
The HVACR industry is changing to lower GWP refrigerants. Due to this change technicians are finding themselves faced with the new challenge of dealing with refrigerants classified as mildly flammable (ASHRAE Safety Classification A2L). While these refrigerants are only one step in flammability above the A1 safety classification that most technicians are used to dealing with, there are new best practices and regulations technicians need to observe when dealing with the new class of refrigerants. To help technicians navigate these changes, TruTech Tools has put together this resource page dedicated to A2L refrigerants.
