Claim This BusinessAbout Johnstone Supply
Johnstone Supply operates as a heating equipment supplier in Golden Valley, Minnesota, serving contractors and trades professionals from its location at the edge of the Twin Cities metro area. The business holds a 4.3-star rating compiled across 52 customer reviews, reflecting a generally solid reputation among its client base of installation and service professionals. As a distributor focused on the professional trade, the company stocks manufacturer inventory including furnaces, split systems, mini-split configurations, and associated installation components for residential and light commercial applications. The Golden Valley store maintains standard weekday hours with reduced Saturday availability, making it accessible for contractors who need to replenish inventory between scheduled jobs or respond to unexpected project requirements.
The supplier differentiates itself through contractor-only distribution, meaning it serves licensed professionals rather than retail homeowners directly, a model that streamlines purchasing for those in the trade. Website listings show the business carries extended warranty options on equipment, which can provide added protection for contractor-backed installations. The product catalog spans multiple system types including single-packaged units, split systems, variable capacity systems, and multi-zone configurations, covering both traditional forced-air setups and newer inverter-driven technology. For installers handling diverse project types, this breadth allows a single supplier relationship for varied applications rather than fragmenting purchases across multiple distributors.
Customer feedback highlights specific team members who have earned recognition for responsive service. Multiple reviewers describe a staff member named Mark who answers phone calls and will open the location after regular hours when contractors face time-sensitive situations. Another review describes the team as providing quick responses and well-stocked inventory that supports same-day project needs. One contractor recounts choosing this location over other Johnstone branches specifically because pricing proved more fair, noting the team goes out of their way to visit this store despite alternatives being available. These accounts suggest the Golden Valley location has cultivated a reputation for accommodating professional schedules and maintaining competitive terms.
