Johnstone Supply operates as a heating equipment supplier in Anderson, South Carolina, serving contractors across the region with an extensive catalog of HVAC components and systems. The location holds a 3.9-star rating compiled from 15 customer reviews, reflecting a mixed but actively engaged client base. Store hours run Monday through Friday from 8 AM to 5 PM, with Saturday and Sunday closed. The business functions as a commercial distributor requiring contractor accounts for purchases, a model that distinguishes it from retail HVAC shops serving end homeowners directly.
The product lineup at this Johnstone Supply location spans multiple categories pulled from their website: single packaged units, split systems, mini-split systems, evaporator coils, gas and oil furnaces, air handlers, field-installed accessories, multi-zone and single-zone systems, and variable capacity systems. Extended warranties are available on select residential unitary equipment. The Anderson branch carries management expertise transferred from other regional stores, and reviewers specifically note the location maintains inventory beyond standard stock levels, including the ability to special order uncommon components for contractor projects.

Mary Pfeiffer noted the team went out of their way to special order and keep items in stock. Mason Owens reported finding exactly what he needed with polite, helpful service.
