The bill aims to expand the scope of work for HVAC/refrigeration specialty electricians in Washington State, specifically allowing them to perform certain electrical tasks related to ductless mini-split HVAC systems. The legislature recognizes the growing popularity of these systems due to their cost-effectiveness and energy efficiency, as well as the current shortage of certified electricians. The new legal language establishes that HVAC/refrigeration electricians can install, repair, replace, or maintain branch circuits connecting outdoor and indoor units of ductless mini-split systems in residential and multifamily homes, as well as other designated construction types.

Additionally, the bill introduces a new section to chapter 19.28 RCW that outlines the specific electrical work HVAC/refrigeration electricians are permitted to perform on ductless mini-split systems. This includes working with single-phase circuits, wiring for condensate pumps, disconnect switches, and conduit systems, provided that the equipment is certified by an accredited electrical product testing laboratory and adheres to the manufacturer's specifications. The bill ensures that the department of labor and industries retains the authority to modify the scope of work for these specialties while maintaining their ability to conduct the specified tasks.
