Refrigerant recovery is the process of safely removing the gas from an HVAC system before it is serviced or replaced. This must be done using a specialized recovery machine and tank to prevent the gas from venting into the atmosphere. It is a legal requirement enforced by the EPA and must be performed by an EPA 608 Certified technician. Whether you are upgrading to a new R454B System or fixing a leak, this step is mandatory. We provide information on these regulations in our R454B Transition guide. Proper recovery allows the refrigerant to be recycled or destroyed safely, protecting the environment.
