Gensco Inc.

Gensco Inc. has anchored its reputation as a family-owned wholesale distributor and manufacturer of HVAC equipment and supplies since 1948, earning a perfect 5-star rating from six verified reviews. Headquartered in Fife, WA, with 26 branches spread across Washington, Oregon, Idaho, Montana, and Alaska, Gensco operates a Hillsboro, OR location that directly serves contractors in the Portland metro and surrounding communities. The company functions as a business-to-business partner rather than a retail walk-in operation, supplying equipment, parts, and technical support to residential and commercial contractors who depend on reliable inventory access and knowledgeable counter staff.

The 2025 AD Giving Back Award and the Business Leader of the Year Award recognize Gensco as an industry leader whose mission centers on delivering quality products the first time, every time. Award-winning tech services and dedicated training facilities equip contractor customers with continued education and technical support, while dedicated commercial quoting and marketing solutions give those customers a competitive edge. Premier brand partnerships and a collaborative business model set Gensco apart from standard distributors, supporting both field technicians and the homeowners who ultimately rely on those contractors for installs, service, and repairs.

Customer reviews name Bob and the Portland Gensco counter team as standouts, with reviewer Aaron Stoddard specifically thanking Bob for help during a recent service call. Aviator Heating & Cooling described the Hillsboro branch as a go-to supply house staffed by friendly professionals, while Pyramid Heating & Cooling called the Portland counter team the best across their decade-long working relationship. Thomas Alsop credited the team with reviving a Donut Wednesdays tradition, a small cultural touch that reviewers say reflects the welcoming atmosphere Gensco maintains for contractor customers.
