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 across 10 states. Based in Sacramento, California, the company has built its reputation over decades serving HVAC contractors and refrigeration professionals who depend on specialized parts and equipment. The Sacramento branch maintains standard hours Monday through Friday from 7 AM to 5 PM, serving both local contractors and those traveling from surrounding areas. With 15 verified reviews maintaining a 4.7-star rating, the business demonstrates consistent customer satisfaction among the trade professionals who source components for residential and commercial projects.

What distinguishes RSD from standard supply houses is their comprehensive inventory depth and specialized divisions. The company offers the Refrigerant Suite as a central clearinghouse for all refrigerant-related information, particularly valuable as industry regulations evolve around A2L refrigerants. Their Total Control division partners directly with HVAC contractors to provide building automation systems, professional services, and training. RSD also stocks fiberglass cooling towers ranging from 5 to 500 tons, and maintains an in-house mobile app called RSD Notes that helps contractors organize parts and specifications while working in the field. The business provides DDC Training through Total Control University, offering online registration for contractor education.

Customer reviews consistently highlight specific staff members by name, with Sean Perez frequently mentioned as having extensive product knowledge accumulated over years of service. One reviewer described the staff's understanding of product applications as "uncanny," noting their ability to match parts to specific repair scenarios. Amber Taylor specifically praised the front-counter experience, describing efficient transactions where contractors get in and out quickly. Kevin Vanhuss, a contractor himself, recommended RSD as essential for any HVAC professional who wants to avoid disservicing their customers by sourcing inferior parts. The consensus among reviewers emphasizes that RSD stocks difficult-to-find components and can special-order items not regularly carried, making them a critical resource for contractors facing time-sensitive repairs.
