About Johnstone Supply
Johnstone Supply operates as a heating equipment supplier in Melbourne, Florida, holding a 4.2-star average across 44 customer reviews. The location serves contractors and trades professionals throughout Brevard County, stocking residential and commercial HVAC equipment for installation and replacement projects. Operating hours run Monday through Friday from 7:30 AM to 5:00 PM, with weekend availability currently closed.
The supplier maintains an extensive inventory spanning multiple equipment categories, including split systems, mini-split systems, single packaged units, gas furnaces, oil furnaces, air handlers, evaporator coils, and variable capacity systems. Commercial offerings cover single packaged units and field-installed accessories, while residential lines include air handlers, extended warranties, and multi-zone configurations. A reviewer specifically notes the location carries items that competitors cannot source, suggesting depth in specialized inventory.
Customer feedback highlights mixed experiences with staff interactions. Multiple five-star reviewers commend Chris at the front desk for knowledge and helpfulness, with one noting the person deserves recruitment. Additional positive reviews cite great prices, reliable service, and always having necessary parts in stock. However, two one-star reviews raise concerns: one customer encountered what they described as unhelpful counter staff, while another noted the location does not sell to the general public, limiting access to ductboard and similar materials for homeowner repairs.
What Customers Say
5 of 8 reviewers award five stars, praising staff knowledge, competitive pricing, and product availability. The single one-star reviews cite unfriendly counter service and an instance where the business would not sell materials to a homeowner, indicating this operates as a contractor-only supply house rather than a retail outlet for general public purchases.
