About 509 Ductless, LLC
509 Ductless, LLC operates from Selah, Washington, serving residents throughout the Yakima Valley including nearby Union Gap and Tieton. Founded by Javier, the company holds an A+ rating with the Better Business Bureau and has accumulated 87 customer reviews averaging 4.9 stars. The company specializes in both ductless mini-split systems and traditional forced-air heating and cooling, offering installation, maintenance, and repair services for residential and light commercial properties. Their service department, 509 Mechanical Services, handles diagnostics and routine maintenance across all system types.
What distinguishes 509 Ductless from regional competitors is their dual expertise in ductless and traditional HVAC technologies under one roof. The company installs ductless systems featuring Hot-Start technology, which delivers immediate warm air without the energy waste of cycling on and off. Their 509 Mechanical Services division provides dedicated service calls for troubleshooting and preventative maintenance, giving customers a clear point of contact for ongoing system care. This combination of installation and service capabilities means homeowners avoid the common frustration of hiring separate companies for new equipment and eventual repairs.
Customer reviews frequently name specific technicians who delivered exceptional service. Javier's team installed a multi-head mini-split system for Jeremy S., saving his sister thousands compared to another contractor's bid. For Shelli and Mike H., technicians Randy and David solved a challenging installation in a confined space that another company had declared impossible. Reviewer Ashleigh Evangelista praised the entire crew, noting that Juvenal conducted friendly inspections, Javier provided thorough estimates, and Daniel and Jacob replaced her furnace and AC while entertaining her toddler and playing with her dog. The consistent thread across reviews is that every technician explained their work, cleaned up completely, and stayed true to quoted prices.
