Allowing HVAC/refrigeration electricians to perform certain electrical work on ductless mini-split HVAC systems.

HB 1681 allows HVAC/refrigeration specialty electricians in Washington to install, repair, replace, or maintain the specific electrical circuits connecting outdoor and indoor units of ductless mini-split HVAC systems in residential and certain multifamily homes. It permits work on single-phase circuits under 250 volts/20 amps, including wiring for condensate pumps and related components, provided the equipment is certified and follows manufacturer specifications. The bill directly affects these specialty electricians (expanding their scope) and benefits homeowners and builders by increasing available labor, reducing costs, and addressing a statewide shortage of certified electricians. Key requirements include adherence to manufacturer wiring instructions and department-designated construction types, without altering the Department of Labor & Industries' oversight authority.
