Johnstone Supply

Johnstone Supply operates from 1212 Dalton Ave in Cincinnati, serving the broader Ohio Valley region with heating equipment and contractor supplies. The business holds a 4.3-star rating across 26 verified reviews, reflecting decades of service to both residential homeowners and professional HVAC contractors. Their retail operation includes an on-site inventory of specialty heating components, a professional training academy, and account-based ordering for qualifying commercial customers.

What distinguishes Johnstone Supply from standard supply houses is their investment in contractor education through Johnstone Solutions University, offering accredited training programs that count toward apprenticeship hours. The company positions itself as a business partner rather than a simple parts supplier, guiding clients toward operational efficiency and profitability. Their tagline emphasizing tech-in-the-truck efficiency reflects a focus on mobile service optimization for field technicians.

Reviewers consistently flag the rapid turnaround and in-stock inventory as differentiators. Judy Mondillo noted quick installation turnaround with clear communication from sale through completion, while Lee Hodges praised their reliable part availability. Stephen Mergner specifically credited the training programs and commercial expertise. A lone negative review from Bradley Schenck cited refusal of retail sales to non-account holders, suggesting the business prioritizes contractor relationships over walk-in retail traffic.
