New Nest Products


Nest recently added some new colors to the thermostat. Now you can get copper, black, white and stainless steel. A new outdoor camera is also available that works 24/7 rain or shine. It features a built in mic/speaker for 2 way communication to your connected device. The Nest Protect smoke alarm verbally calls out carbon monoxide or smoke alarms and exactly where they are occurring.  All part of a total home connected system that also works with thousands of other connected devices.

Become a Nest Pro Contractor and start selling more while building smart home systems for your customers. Customers of Nest Pro contractors enjoy a longer 5 year warranty. Nest Pro contractors also sell more jobs using widely recognized Nest products that are in demand. Contact anyone at Johnstone Supply for more information or to purchase Nest devices.

Welcome South Bend and Elkhart Branches!

indianaEffective January 1, 2017 the existing South Bend and Elkhart, IN Johnstone branches joined the Muskegon group. This brought the group total to 8 stores in Western Michigan and Northern Indiana. Former South Bend owner Andy Peck will continue to work with the stores in 2017 to ensure a smooth transition but will then change his focus onto other future endeavors. You can expect to see the same team members you have come to know as well as their high level of customer service. The entire Muskegon team welcomes South Bend and Elkhart employees to our team!

In addition to all that Johnstone Supply offers, the South Bend group brings to Muskegon added knowledge, product and expertise in refrigeration and commercial products. Muskegon in turn brings updated computer technology, rf bar-coding and several added product lines to South Bend. Customers can also expect to see enhanced deliveries and services once the transition is complete.

Let us know if you have any questions.
