Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Lafayette, Louisiana, serving the local HVAC contractor community from their location on Johnston Street. The distributorship maintains standard business hours Monday through Friday from 7 AM to 4 PM, closed on weekends. As a commercial supplier rather than a residential service contractor, they provide equipment, parts, and tools to professional HVAC technicians and installation businesses throughout the Acadiana region.

What distinguishes Johnstone Supply is their contractor-only distribution model, requiring an account for purchasing access. Their product catalog spans multiple HVAC categories including single packaged units, split systems, mini-split systems with multi-zone and variable capacity options, air handlers, evaporator coils, and both gas and oil furnaces. The company offers extended warranty programs on equipment and maintains a cross-reference search tool for identifying equivalent parts across manufacturers.

Because this is a B2B supplier rather than a residential service company, they do not accept homeowner calls for equipment purchases or troubleshooting. Contractors in the Lafayette area can establish accounts to access their full inventory, request pricing on commercial equipment, and utilize specialized contractor tools available through their online portal.
