Prefiled 01/09/26. Read first time 01/12/26. Referred to Committee on Labor & Workplace Standards.

AN ACT Relating to directing the department of labor and industries to adopt rules clarifying the scope of work for HVAC/refrigeration specialty electricians for ductless mini-split systems; adding a new section to chapter 19.28 RCW; and creating a new section.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:

NEW SECTION. Sec. 1. The legislature finds that the installation of mini-split heating, ventilation, and air conditioning systems has increased significantly across the state as consumers seek efficient, zonal heating and cooling options. State and local energy codes and electrification policies have further accelerated the adoption of these systems.

The legislature further finds that electricians holding the HVAC/refrigeration specialty certification are trained and qualified to safely perform electrical connections between outdoor and indoor units of mini-split systems when those connections are made in accordance with manufacturer specifications. These connections involve standardized wiring methods, clearly identified terminals, and equipment certified as a system by accredited electrical product testing laboratories.
