Is it legal to intentionally vent HFC refrigerant like R-410A while servicing equipment?

No. The venting ban covers HFCs as well as ozone-depleting refrigerants.

  1. Yes, because HFCs do not harm ozone
  2. No, the venting ban covers HFC substitutes too ✔
  3. Yes, if it is under one pound

Why: Section 608 prohibits intentionally venting ozone-depleting refrigerants and their substitutes, such as HFCs, while maintaining, servicing, repairing or disposing of equipment. Recover it instead.

Huh, didn't know that: EPA says installing an R-410A mini-split, even just connecting pre-charged lines, requires Section 608 certification.

Why did the HVAC tech go to therapy? He had too many vents to clear!
