Gensco Inc.

Gensco Inc. has supplied the Pacific Northwest HVAC industry since 1948, making it one of the region's oldest continuously operating wholesale distributors. Based in Kirkland, Washington, this family-owned company operates 26 branches across Washington, Oregon, Idaho, Montana, and Alaska. With 21 customer reviews yielding a 3.5-star average, Gensco primarily serves licensed contractors rather than homeowners, though walk-in customers report mixed experiences depending on whether they have an account established.

What distinguishes Gensco from typical supply houses is their dual role as both distributor and manufacturer, with Columbia Manufacturing as a key internal brand. Their website emphasizes an award-winning tech services team and training facilities, alongside dedicated commercial quoting and marketing support for contractor partners. The company carries industry-leading brand partners and promises first-time quality service on every order, backed by daily deliveries throughout their five-state territory.

Reviewers name several Kirkland counter staff who deliver exceptional service. Steve earned specific praise for quickly sourcing a hard-to-find 3X4x5 HVAC wye fitting that Ferguson did not carry, completing the transaction in minutes. Another reviewer credits the entire Kirkland team, naming Denzel, Rob, Marco, and Steve for getting orders right the first time. However, one contractor reported a 12-minute hold and difficulty establishing a new account, suggesting the account setup process may present barriers for some seeking parts.
