This 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 legislation recognizes the growing popularity of these systems for efficient heating and cooling, driven by energy codes and consumer demand. It addresses the current shortage of certified electricians by permitting HVAC/refrigeration electricians to install, repair, replace, or maintain branch circuits connecting outdoor and indoor units in residential and multifamily homes, as well as other designated construction types.

The bill introduces a new section to chapter 19.28 RCW, detailing the specific electrical work that HVAC/refrigeration electricians can undertake for ductless mini-split systems. This includes handling single-phase circuits, wiring for condensate pumps, disconnect switches, and conduit systems, provided that the equipment is certified by an accredited testing laboratory and adheres to the manufacturer's specifications. The legislation ensures that while it expands the electricians' scope of work, it does not limit the Department of Labor and Industries' authority to modify these provisions in the future.
