The Washington Refrigerant Deadline Has Passed — Are Your Facilities Compliant?
Washington businesses with refrigeration or HVAC systems holding 200–1,499 lbs of refrigerant (GWP >150) must register by March 15, 2026, with annual reporting due March 15, 2027. Missing these deadlines increases enforcement exposure, penalties and operational risk.
CoolSys simplifies Washington Refrigerant Management—handling registration, documentation and reporting so your facilities stay compliant, protected and audit-ready.
As of January 1, 2026, expanded federal refrigerant regulations are fully enforceable.
Combined with Washington state requirements under WAC 173-443, more refrigeration and HVAC systems now fall under mandatory leak tracking, registration and reporting obligations.
Washington state regulations under WAC 173-443 now require medium facilities to:
This is no longer future guidance. It is enforceable compliance.

In parallel, federal regulations under the AIM Act and Environmental Protection Agency (EPA) Section 608 expanded as of January 1, 2026:
Washington operators must comply with both state refrigerant management rules and federal 2026 expansion requirements.
