Trusted Plumbing & HVAC Wholesale Supplier in Seattle
Founded in 1945 by Howard Keller, our company began in a modest 600-square-foot warehouse and has grown into a multi-story corporate headquarters with over 70 branch operations across nine western states. As a family-owned and managed business, we remain committed to personalized service despite our national ranking as the 20th largest plumbing supply wholesaler. Our divisions serve residential, commercial, and industrial markets with products ranging from plumbing and HVAC to pool and spa equipment. We pioneered the separation of wholesale activities between plumbing contractors and retailers, ensuring comprehensive support for new construction and post-construction projects.Our in-house Training Center provides hands-on education for customers and employees on HVAC, ductless, and hydronic systems. With a corporate slogan of 'we don't want orders, we want customers,' we emphasize long-term relationships over transactional interactions. Our Keller Kitchen and Bath Showcases feature top-quality products at competitive prices. Representing Kohler since 1951, we continue expanding our product diversification while maintaining our Pacific Northwest roots. Our truck fleet ensures prompt delivery of orders directly to job sites, supporting both local and international market segments.
