H.C. Oswald Supply Company Inc

H.C. Oswald Supply Company Inc operates as a heating equipment supplier serving the Bronx and surrounding New York metropolitan area. With 205 reviews generating a 4.9-star rating, the company has built a reputation for stocking cast iron radiators, boilers, HVAC components, and specialized heating supplies. Their retail operation welcomes homeowners and contractors seeking parts and equipment, with a physical location in the Bronx and online purchasing capabilities. The business maintains standard weekday hours from 8 AM to 5 PM, closed on weekends.

The supplier differentiates itself through aggressive inventory positioning and rapid fulfillment. Unlike traditional plumbing supply houses with extended lead times, Oswald Supply maintains stocked radiators and commonly needed heating components on-site, enabling two-day delivery on most orders. Their pricing structures frequently undercut local competitors by significant margins, with one reviewer noting costs approximately one-third of nearby plumbing supply establishments. The company offers products across multiple categories including boilers/heating supplies, HVAC equipment, radiators, mini splits, oven parts, and trash chute doors/parts, serving both residential replacement projects and larger renovation needs.

Customer testimonials highlight specific positive experiences with technical support staff. Robert, referenced by name in multiple reviews, has assisted customers by contacting original boiler manufacturers to identify correct part numbers and ensuring no additional installation items were needed. One customer described receiving next-day gasket delivery processed within hours of ordering, while another noted a wet pack combustion chamber liner arrived in three days with helpful phone guidance from technical support. The shipping speed and staff willingness to troubleshoot installation questions appear as recurring themes across customer feedback.
