About Johnstone Supply
Johnstone Supply operates as a heating equipment supplier in Long Beach, California, earning a 4.3-star rating across 36 customer reviews. The branch serves contractors and trades professionals seeking wholesale heating components, with a physical location at 562-595-4822 and standard commercial hours spanning Monday through Friday from 7 AM to 5 PM, plus Saturday morning availability until 11 AM. Customers consistently note the operation functions as a trade-only wholesale facility rather than a retail outlet catering directly to residential homeowners.
What distinguishes this Long Beach supplier is its emphasis on professional trade relationships and the personalized attention that several reviewers highlight. Multiple customers specifically credit Carlos, a team member who has walked clients through complex issues and gone beyond standard support expectations. The operation maintains ready inventory of heating components, with one reviewer noting they consistently stock required parts, a critical factor for contractors managing time-sensitive installations. While the wholesale model means direct residential sales are not available, the team demonstrates willingness to connect customers with appropriate retail partners.
Customer narratives reveal both strengths and service gaps worth noting. Carlos receives consistent recognition for going above and beyond, with one reviewer describing a scenario where he walked a customer through a problem resolution completely. Conversely, three separate reviewers flag responsiveness issues ranging from rude interactions to failed quote follow-ups, suggesting inconsistency in customer-facing processes. One military facilities reviewer emphasizes the importance of accurate parts for critical applications, while another highlights the team's referral approach when they cannot directly fulfill a customer's needs.
What Customers Say
Six of eight reviewers award 4-5 stars, praising parts availability and knowledgeable staff, while negative reviews cite rude salespeople and abandoned quote requests. Three reviewers specifically mention Carlos by name for exceptional support.
