Johnstone Supply

Johnstone Supply operates as an HVAC equipment distributor in Santa Clarita, California, holding a 3.9-star rating drawn from 20 customer reviews. This location, situated in the Valencia area, functions as a contractor-only supply hub, meaning the business exclusively serves licensed HVAC professionals rather than homeowners undertaking DIY projects. The supply center maintains standard commercial hours across weekdays, with reduced Saturday availability, and can be reached at (661) 775-8981.

What distinguishes this distributor from typical supply houses is their contractor-only sales model, which keeps operations efficient and prevents the delays often associated with retail counter traffic. Their inventory spans multiple HVAC categories including split systems, mini-split systems, gas and oil furnaces, air handlers, evaporator coils, and packaged units. The branch offers local delivery service and maintains robust sourcing capabilities for parts not currently in stock, a critical advantage for contractors managing time-sensitive installations.

Customer feedback highlights the Valencia branch team, with specific recognition going to Louie and Ryan for their product knowledge and responsiveness. One reviewer described Louie as providing A1 service and sharing technical knowledge generously. Another contractor noted that Ryan and his team consistently have equipment ready when ordered online and have assisted with warranty parts procurement. The counter staff overall receives praise for their friendly demeanor and technical expertise, with multiple long-term contractors indicating they routinely return for their supply needs.
