Greenberg Supply Co Inc

Greenberg Supply Co Inc operates from 809 East 5th Street in Wilmington, Delaware, serving the Mid-Atlantic region as a wholesale distributor for professional HVAC contractors, maintenance departments, and property managers. Founded in 1960, the company has accumulated 129 customer reviews yielding a 4.5-star rating, reflecting decades of steady service to the trade. Their client base spans residential, commercial, and industrial sectors across Delaware, southeastern Pennsylvania, and southern New Jersey.

The company distinguishes itself as a wholesale-only distributor, focusing on equipment, parts, and supplies rather than end-user installation. Their inventory encompasses heating, cooling, and water heating systems along with technical support resources for professional technicians. This trade-only model means Greenberg Supply serves contractors who then perform residential and commercial installations, positioning them as a supplier-of-supplies within the regional HVAC supply chain.

Named technicians appear sparingly in reviews, but Robert Tillinghast awarded five stars praising the staff and service quality. Conversely, Michael Williams described a frustrating call where he felt dismissed while seeking a heater part to keep his family warm. Kim Tarriero recounted being sold an incorrect part, making a round trip from South Jersey only to face a refusal on return despite the error originating from the distributor.
