RSD - Refrigeration Supplies Distributor

RSD - Refrigeration Supplies Distributor operates as the largest independently owned refrigeration parts and HVAC equipment wholesaler in the western United States, with 80 locations spanning 10 states. Based in Seattle at 612 S Nevada St, this distributor serves contractors across the Pacific Northwest including Tacoma, Bellevue, and Everett, supplying commercial and residential HVAC professionals with equipment, parts, and technical support. The company maintains a 5.0-star rating from 10 verified reviews, reflecting consistent satisfaction among contractor customers who rely on their inventory of compressors, refrigerants, controls, and specialized components for service calls and installations.

What distinguishes RSD from standard parts suppliers is their comprehensive approach to contractor support. They offer the Refrigerant Suite, a centralized platform for all refrigerant-related compliance information essential for technicians navigating evolving environmental regulations. Their Total Control division provides building automation systems, professional services, and DDC Training through Total Control University, helping contractors expand into building management systems. RSD also stocks fiberglass cooling towers ranging from 5 to 500 tons, and their mobile app RSD Notes allows technicians to access organized part specifications and supplier contacts directly from job sites.

Customer reviews highlight specific technicians who deliver exceptional service. Dominic receives recognition for top-tier customer support, while manager "A" at one branch resolved a parts error by providing the correct component without requiring the customer to return the incorrect item, a decision that earned loyalty and a commitment to increased purchasing. Carlos Rivas notes RSD consistently sources hard-to-find parts in a timely fashion, a critical capability for contractors managing urgent service calls where parts availability directly impacts resolution time.
