The problem with this now is that as of January 1st, 2018 you can no longer purchase R-410A unless you are section 608 certified with the Environmental Protection Agency. Purchasing has been locked down to only certified technicians. This new rule is known as the ‘ Refrigerant Sales Restriction ‘. These restrictions already existed on HCFC and CFC refrigerants but they were now moved over to HFC refrigerants as well. This included R-410A. What this means is that you are no longer legally able to purchase R-410A unless you are 608 certified with the EPA. Now, there are a few slight exceptions to this such as:
