Welcome to Johnstone Supply

Our Vision: "To become our customer's preferred wholesaler by exceeding expectations through quality service, added value and caring employees."

Kalamazoo Remodeled Showroom & Dock!

Check out our recently remodeled showroom & dock area in the Kalamazoo branch. In the showroom we raised the ceiling, installed new flooring, new counter, new slatwall and roll around
gondolas. In addition, updates to the offices, all lighting and a new coffee and popcorn area were completed. Bathrooms were also updated. We then added a pickup dock that allows you to load at vehicle level while staying out of the rain. Come see the many amazing improvements to make it even better to do business with Johnstone Supply!

New Branch in Benton Harbor!

To better serve existing and new customers we opened our 6th branch on October 12, 2015 in Benton Harbor. The new location is located at 2106 M-139 right next to LeValley Chevrolet. Easy access off of I-94 at exit 28 Scottdale Road.

Meanwhile the building is undergoing a large addition to the warehouse portion so a complete inventory of larger equipment type items and installation products will not be available until November 25.

Stop in and say hi to branch manager Dave Brosco and the rest of the Benton Harbor team!

Our company was recently selected to be the Fujitsu VRF AirStage distributor. We are the only distributor with this designation in Michigan!

The extremely efficient Fujitsu VRF system allows from 6 to 24 tons with up to 45 heads on one system. Depending on the configuration you can cool in one part of the building while heating in another. In order to sell this advanced product you will need to attend our Fujitsu R.A.I.T training class.
Please inquire if interested!
