Claim This BusinessAbout Johnstone Supply
Johnstone Supply operates as a heating equipment distributor serving licensed HVAC contractors in Port Richey, Florida, and the surrounding Gulf Coast region. The location maintains a 4.4-star average rating compiled from 46 customer reviews, reflecting generally positive interactions with professional tradespeople who frequent the counter. The warehouse stocks residential and commercial HVAC equipment including single packaged units, split systems, mini-split systems, evaporator coils, gas furnaces, oil furnaces, and air handlers, catering specifically to installation and service professionals rather than do-it-yourself homeowners.
What distinguishes Johnstone Supply from general retail outlets is its wholesale-only distribution model. The store carries manufacturerextended warranties on equipment purchases, providing contractors with added protection for their installation projects. Their catalog features multi-zone and variable capacity systems for modern high-efficiency homes, along with field-installed accessories that enable custom system configurations. Online contractor tools allow account holders to check stock availability, request cross-references, and manage procurement outside standard counter hours.
One reviewer highlighted a specific instance of exceptional responsiveness: Vince at the Port Richey location opened the store on a Saturday morning with minimal notice to help a contractor facing an emergency cooling situation, going beyond standard operating hours to resolve the customer's need. Another reviewer described being admitted just before closing time to purchase a needed component that saved their day. Staff knowledgeability on Parts availability appears repeatedly across satisfied reviews, with long-term commercial accounts praising the team's familiarity with complex installation requirements.
