Johnstone Supply

Johnstone Supply has operated as a heating equipment supplier in Norcross, Georgia since 1983, serving the greater Gwinnett County area including Duluth, Lilburn, and Peachtree Corners. The business maintains a 4.2-star rating across 45 verified customer reviews, with operating hours Monday through Friday from 7:30 AM to 5:00 PM. As a supplier-focused operation, the company stocks replacement components and systems for residential and light commercial heating applications, maintaining inventory for immediate contractor pickup or project fulfillment.

Unlike retail-focused HVAC companies, Johnstone Supply emphasizes wholesale distribution to licensed contractors, particularly those serving the suburban Atlanta heating market. The business provides will-call pickup and same-day inventory access for registered trade professionals. This trade-only model means the company prioritizes contractor accounts over retail walk-in traffic, which some residential customers have found limiting when seeking direct purchase or consultation.

Customer experiences vary significantly at this location. Steven Hill, a small repair business owner, describes the team as helpful and friendly, noting staff directed him to appropriate resources when inventory was unavailable. However, multiple reviewers report frustration with customer service interactions, particularly around warranty claims and refund requests. One customer described a multi-week dispute over a defective motor that allegedly damaged additional system components, with unresolved satisfaction at the time of posting.
