Overview

Johnstone Supply is a cooperative wholesale distributor serving heating, ventilation, air-conditioning and refrigeration professionals. Its locally operated stores provide equipment, replacement parts, tools, controls and supplies from a broad range of manufacturers. Contractors use branches, digital ordering and technical support to source products for installation, maintenance and repair work. Johnstone's model combines a national distribution network and shared purchasing capabilities with independent local ownership, distinguishing it from both an HVAC contractor and a centrally owned consumer retail chain.
