The Airflow: October 13, 2026
Free refrigerant training, a new look at reclaimed supply, and a local-code check worth making before your next outdoor unit install.
🔦 Fun Fact
Your EPA Section 608 credential does not expire. Universal certification also requires a proctored Core test; an open-book Core result cannot count toward it.
😆 Laugh of the Day
Why did the thermostat get invited to every meeting?
It knew how to keep things comfortable.
🧰 Free CO2 and Propane Training Opens for the New Season
NASRC has opened registration for its 2026–27 natural refrigerant training events. The current lineup starts with a December 2–3 workshop in Stockton, California, followed by summits and workshops in 2027. Classroom sessions and hands-on equipment training focus on CO2 and propane. If commercial refrigeration is on your career path, check the location pages before arranging time off.
♻️ EPA Reports More HFC Refrigerant Reclaimed in 2025
EPA’s September 24 dashboard update reports about 10% more HFC refrigerant reclaimed in 2025 than in 2024, with R-410A and HFC-134a driving much of the increase. Reclaimed supply matters for servicing existing systems as virgin HFC supply declines. The dashboard includes downloadable data, useful if you want the figures behind the trend.
📋 Outdoor HVAC GFCI Rules Need a Local Check
ACCA’s September resource center addresses the expired temporary NEC exemption for listed outdoor HVAC equipment. State adoption and amendments differ, so the requirement does not apply identically everywhere. Use the center to review the issue, then confirm your jurisdiction’s current code and equipment requirements before planning an installation. Nuisance-tripping concerns do not authorize bypassing required protection.
Make room for one useful training session, and give the local requirements a fresh look before the next job.
