Claim This BusinessJohnstone Supply operates as a heating equipment supplier in Lawrenceville, Georgia, serving contractors and homeowners across the Atlanta metropolitan area including Suwanee, Duluth, and Buford. The store maintains weekday hours from 7:30 AM to 5 PM, Monday through Friday, with a rating of 3.0 stars compiled from four customer reviews. As a distributor specializing in residential and commercial HVAC equipment, the business stocks major brands across multiple categories from gas furnaces to mini-split systems.
What distinguishes this supplier is its contractor-first approach featuring Express Locker Pickup, which allows professional installers to retrieve parts outside standard hours without waiting in-store. The product catalog spans single packaged units, split systems, manufactured housing equipment, air handlers, evaporator coils, and field-installed accessories. Extended warranties are available on select residential unitary systems, and the location offers training calendar events for contractor continuing education.
Customer experiences vary significantly. Arif Ghani praised the company for good pricing and named Mr. Jesus as particularly helpful during their transaction. However, two reviewers reported significant frustrations: Alex Mears spent 30 minutes on hold before being transferred to the Alpharetta location, while Jared Still noted the phones went unanswered entirely, describing staff as very rude.
Three of four reviews rate the business at 1 star, citing poor phone communication and rude staff. The single 5-star review from Arif Ghani specifically names Mr. Jesus as helpful and notes good pricing. Overall sentiment leans negative, with the minority positive review highlighting exceptional customer service from a named employee.
