HVAC Trade Groups Push to Delay September 2026 GFCI Deadline
The Air-Conditioning, Heating, and Refrigeration Institute told the National Electrical Code technical committee in late August that the September 1, 2026 compliance deadline for HVAC GFCI requirements should be delayed. AHRI and ACCA reported that compatibility issues between GFCI products and HVAC equipment remain unresolved. Test data shows HVAC equipment can produce leakage current high enough to trip Class A GFCI devices. This happens even when measured touch current stays below levels that could injure someone.
The timing creates real problems for contractors. If the requirement takes effect as scheduled, you could face callbacks when GFCI breakers trip and shut down equipment during peak cooling season. That means potential liability exposure and angry customers without AC during heat waves. The technical issues suggest the equipment itself may be safe. However, it may be incompatible with current GFCI technology.
Monitor updates from AHRI and your local code officials to see if the deadline gets extended before September 1.
Key Takeaways:
- AHRI requested delay of September 1, 2026 HVAC GFCI compliance deadline
- HVAC equipment leakage current can trip GFCIs despite safe touch current levels
- Compatibility issues between GFCI products and HVAC equipment remain unresolved
