Getting the Right Tools:
Most refrigeration tools work just fine with all refrigerants (vacuum gauges, lineset benders, flaring and swaging tools, etc.), however, the following tools may have a compatibility issue:
- Refrigerant Recovery Machines
- Vacuum Pumps
- Manifolds
- Refrigerant Leak Detectors
Contractors should take inventory of the tools they already have and consider upgrading to an A2L compatible tool where necessary. HVAC Distributors stocks a variety of compatible tools that will help you stay up to date. Learn more about getting the right tools for A2L Refrigerant here.
